Precious metal armoured thermocouple mainly consists of precious metal casing, insulating materials, dipole wire materials.   The characteristics of precious metal armoured thermocouples can be summarised as follows: Corrosion resistance good stability of the thermal potential, long-term use of the thermal potential drift is small; The upper limit of the use temperature is high; Armoured thermocouple end is hermetically sealed, no residual gas inside High insulation resistance, precious metal armoured thermocouple at room temperature can reach more than 50MΩ; Product specifications, protection tube materials can be processed according to user requirements Easy to bend, good flexibility, simple installation Resistant to pressure and vibration; Short thermal response time; long service life

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).    

     Beryllium copper is a copper alloy with beryllium as the main alloying element, also known as beryllium bronze. It is an advanced elastomeric material with the best performance among copper alloys, and its strength can be close to that of medium-strength steel.      Beryllium bronze is a supersaturated solid solution copper-based alloy, is the mechanical properties, physical properties, chemical properties and corrosion resistance of a good combination of non-ferrous alloys, after solid solution and aging treatment, with a high strength limit, elasticity limit, yield limit and fatigue limit as high as the special steel, but also has a high degree of electrical conductivity, thermal conductivity, widely used in the manufacture of various types of moulds and moulds, replacing the production of steel, high-precision, complex shape moulds, welding electrode materials, pressing and pressing materials. Widely used in the manufacture of various types of mould inserts, alternative steel production of high-precision, complex shape of the mould, welding electrode materials, die-casting machines, injection moulding machine punches, wear-resistant and corrosion-resistant work.      Beryllium copper tape is used in micro-motor brushes, mobile phones, batteries and other products, is an important industrial material indispensable to the construction of the national economy.  

Tankii office will be closed from 29th Sept. to 6th Oct. 2023 due to Mid Autumn Festival and National Holiday.   The Origin of Mid-Autumn Festival： "Zhong Qiu Jie", which is also known as the Mid-Autumn Festival, is celebrated on the 15th day of the 8th month of the lunar calendar. It is a time for family members and loved ones to congregate and enjoy the full moon - an auspicious symbol of abundance, harmony and luck. Adults will usually indulge in fragrant mooncakes of many varieties with a good cup of piping hot Chinese tea, while the little ones run around with their brightly-lit lanterns.   We would like to share an ancient poem with everyone:    Tune: Prelude to Water Melody --Su Shi (Song dynasty)   How long will the full moon appear? Wine cup in hand, I ask the sky. I do not know what time of the year. It would be tonight in the palace on high.   Riding the wind, there I would fly, Yet I'm afraid the crystalline palace would be Too high and cold for me.   I rise and dance, with my shadow I play. The moon goes round the mansions red Through gauze-draped window soft to shed. Her light upon the sleepless bed.   Why then when people part, is the moon full and bright? Men have sorrow and joy; they part or meet again; The moon is bright or dim and she may wax or wane. There has been nothing perfect since the olden days. So let us wish that man Will live long as he can! Though miles apart, we'll share the beauty she displays.
