1. Different Ingredients Nickel chromium alloy wire is mainly composed of nickel (Ni) and chromium (Cr), and may also contain small amounts of other elements. The content of nickel in nickel-chromium alloy is generally about 60%-85%, and the content of chromium is about 10%-25%. For example, the common nickel-chromium alloy Cr20Ni80 has a chromium content of about 20% and nickel content of about 80%. The main component of copper wire is copper (Cu), whose purity can reach more than 99.9%, such as T1 pure copper, copper content as high as 99.95%.   2. Different Physical Properties Color - Nichrome wire is usually silver gray. This is because the metallic luster of nickel and chromium is mixed to give this color. - The copper wire color is purplish red, which is the typical color of copper and has a metallic luster. Density - The linear density of nickel-chromium alloy is relatively large, generally around 8.4g/cm³. For example, 1 cubic meter of nichrome wire has a mass of about 8400 kg. - The copper wire density is about 8.96g/cm³, and the same volume of copper wire is slightly heavier than nickel-chromium alloy wire. Melting Point -Nickel-chromium alloy has a high melting point, around 1400 ° C, which makes it able to work at higher temperatures without melting easily. -The melting point of copper is about 1083.4℃, which is lower than that of nickel-chromium alloy. Electrical Conductivity -Copper wire conducts electricity very well, in standard condition, copper has an electrical conductivity of about 5.96×10 guess S/m. This is because the electronic structure of copper atoms allows it to conduct current well, and it is a commonly used conductive material, which is widely used in fields such as power transmission. Nickel-chromium alloy wire has poor electrical conductivity, and its electrical conductivity is much lower than that of copper, about 1.1×10⁶S/m. This is due to the atomic structure and interaction of nickel and chromium in the alloy, so that the conduction of electrons is hindered to a certain extent. Thermal conductivity -Copper has excellent thermal conductivity, with a thermal conductivity of about 401W/(m·K), which makes copper widely used in places where good thermal conductivity is required, such as heat dissipation devices. The thermal conductivity of nickel-chromium alloy is relatively weak, and the thermal conductivity is generally between 11.3 and 17.4W/(m·K).   3. Different Chemical Properties Corrosion Resistance Nickel-chromium alloys have good corrosion resistance, especially in high temperature oxidation environments. Nickel and chromium form a dense oxide film on the surface of the alloy, preventing further oxidation reactions. For example, in high temperature air, this layer of oxide film can protect the metal inside the alloy from further corrosion. - Copper is easily oxidized in air to form a vercas (basic copper carbonate, formula Cu₂(OH)₂CO₃). Especially in a humid environment, the surface of copper will gradually be corroded, but its corrosion resistance in some non-oxidizing acids is relatively good. Chemical Stability - Nichrome alloy has high chemical stability and can remain stable in the presence of many chemicals. It has a certain tolerance to acids, bases and other chemicals, but it can also react in strong oxidizing acids. - Copper in some strong oxidants (such as nitric acid) under the action of a more violent chemical reaction, the reaction equation is (3Cu + 8HNO₃(dilute)=3Cu(NO₃ +2NO↑ + 4H₂O). 4. Different Uses - nickel-chromium alloy wire - Due to its high resistivity and high temperature resistance, it is mainly used to make electric heating elements, such as heating wires in electric ovens and electric water heaters. In these devices, nichrome wires are able to efficiently convert electrical energy into heat. - It is also used in some occasions where mechanical properties need to be maintained in high temperature environments, such as the support parts of high temperature furnaces. - Copper wire - Copper wire is mainly used for power transmission, because its good electrical conductivity can reduce the loss of electrical energy during transmission. In the power grid system, a large number of copper wires are used to make wires and cables. - It is also used to make connections for electronic components. In electronic products such as computers and mobile phones, copper wires can realize signal transmission and power supply between various electronic components.

The manufacturing method of 0Cr13Al6Mo2 high-resistance electric heating alloy is usually a combination of melting and casting.   In addition to 0Cr13Al6Mo2 high-resistance electrothermal alloy, there are other types of high-resistance electrothermal alloys, such as iron-chromium-aluminum alloy, nickel-chromium alloy, etc. These alloys have their own characteristics and advantages in different fields. When choosing an electric heating alloy, it is necessary to consider comprehensively according to factors such as actual application scenarios, working conditions and performance requirements. At the same time, in order to improve the service life and stability of electric heating alloys, it is also necessary to carry out heat treatment, surface treatment and other technological measures for alloy materials.   As an important material for electric heating elements, 0Cr13Al6Mo2 high-resistance electric heating alloy has been widely used in many fields. In the future, with the continuous development of science and technology and the continuous change of social needs, the research and development and application of high-resistance electric heating alloys will continue to expand and deepen, bringing more convenience and benefits to human production and life.

The great achievements of the aerospace industry are inseparable from the development and breakthroughs in aerospace materials technology. The high altitude, high speed and high manoeuvrability of fighter jets require that the structural materials of the aircraft must ensure sufficient strength as well as stiffness requirements. Engine materials need to meet the demand for high temperature resistance, high temperature alloys, ceramic-based composite materials are the core materials. Conventional steel softens above 300℃, making it unsuitable for high-temperature environments. In the pursuit of higher energy conversion efficiency, higher and higher operating temperatures are required in the field of heat engine power. High-temperature alloys have been developed for stable operation at temperatures above 600℃, and the technology continues to evolve. High-temperature alloys are key materials for aerospace engines, which are divided into iron-based high-temperature alloys, nickel-based by the main elements of the alloy. High-temperature alloys have been used in aero-engines since their inception, and are important materials in the manufacture of aerospace engines. The performance level of the engine depends largely on the performance level of high temperature alloy materials. In modern aero-engines, the amount of high-temperature alloy materials accounts for 40-60 per cent of the total weight of the engine, and is mainly used for the four main hot-end components: combustion chambers, guides, turbine blades and turbine discs, and in addition, it is used for components such as magazines, rings, charge combustion chambers and tail nozzles. (The red part of the diagram shows high temperature alloys) Nickel-based high-temperature alloys generally work at 600 ℃ above the conditions of a certain stress, it not only has good high-temperature oxidation and corrosion resistance, and has a high high-temperature strength, creep strength and endurance strength, as well as good fatigue resistance. Mainly used in the field of aerospace and aviation under high-temperature conditions, structural components, such as aircraft engine blades, turbine discs, combustion chambers and so on. Nickel-based high-temperature alloys can be divided into deformed high-temperature alloys, cast high-temperature alloys and new high-temperature alloys according to the manufacturing process.  With the heat-resistant alloy working temperature is higher and higher, the strengthening elements in the alloy is more and more, the more complex the composition, resulting in some alloys can only be used in the cast state, can not be deformed hot processing. Moreover, the increase of alloying elements makes nickel-based alloys solidify with serious segregation of components, resulting in non-uniformity of organisation and properties. The use of powder metallurgy process to produce high temperature alloys, can solve the above problems. Because of the small powder particles, powder cooling speed, eliminating segregation, improved hot workability, the original casting alloy into hot workable deformation of high-temperature alloys, yield strength and fatigue properties are improved, powder high-temperature alloy for the production of higher-strength alloys has produced a new way.

We wish all customers' business snowballing in the coming year.

Platinum-rhodium thermocouple, which has the advantages of high temperature measurement accuracy, good stability, wide temperature measurement area, long service life and so on, is also called high temperature precious metal thermocouple. It is widely used in the fields of iron and steel, metallurgy, petrochemical, glass fibre, electronics, aviation and aerospace. However, it is difficult to adapt to complex environments and narrow space areas that require bending and short thermal response time due to its reduced strength at high temperatures and its sensitivity to environmental pollution.   Precious metal armoured thermocouple is a new type of temperature measurement material developed on the basis of precious metal thermocouple, which has the advantages of vibration resistance, high pressure resistance, resistance to chemical corrosion of the medium, can be bent, short response time and durability.   Precious metal armoured thermocouple mainly consists of precious metal casing, insulating materials, dipole wire materials. It usually filled with magnesium oxide or other insulating materials between the precious metal casing and the dipole wire, in the case of maintaining high-temperature insulation, the dipole wire is in a gas-tight state, that so as to prevent the thermocouple from corrosion and deterioration due to the air or high-temperature gas. (the structure picture of thermocouple wire is as follows)

Beryllium copper and beryllium bronze are the same material. Beryllium copper is a copper alloy with beryllium as the main alloying element, also called beryllium bronze.     Beryllium copper has beryllium as the main alloying group element of a tin-free bronze. Containing 1.7 ~ 2.5% beryllium and a small amount of nickel, chromium, titanium and other elements, after quenching and aging treatment, the strength limit of up to 1250 ~ 1500MPa, close to the level of medium strength steel. In the quenched state plasticity is very good, can be processed into a variety of semi-finished products.   Beryllium bronze has high hardness, elasticity limit, fatigue limit and wear resistance, also has good corrosion resistance, thermal conductivity and electrical conductivity, does not produce sparks when impacted, widely used as important elastic components, wear-resistant parts and explosion-proof tools. Commonly used grades are QBe2, QBe2.5, QBe1.7, QBe1.9 and so on.     Beryllium bronze is divided into two categories. According to the alloy composition, beryllium content of 0.2% to 0.6% is high conductivity (electrical, thermal) beryllium bronze; beryllium content of 1.6% to 2.0% is high strength beryllium bronze. According to the manufacturing process, it can be divided into cast beryllium bronze and deformed beryllium bronze.        Beryllium bronze has good overall performance. Its mechanical properties, i.e. strength, hardness, wear resistance and fatigue resistance are among the top of copper alloys. Its electrical conductivity, thermal conductivity, non-magnetic, anti-sparking and other properties of other copper materials can not be compared with it. In the solid solution soft state beryllium bronze strength and electrical conductivity are at the lowest value, after work hardening, the strength has improved, but the conductivity is still the lowest value. After aging heat treatment, its strength and conductivity increased significantly.       Beryllium bronze machinability, welding performance, polishing performance and general high copper alloy similar. In order to improve the machining performance of the alloy to adapt to the precision requirements of precision parts, countries have developed a lead 0.2% to 0.6% of high-strength beryllium bronze (C17300), and its performance is equivalent to C17200, but the alloy cutting coefficient by the original 20% to 60% (100% for free-cutting brass).
