Are beryllium copper and beryllium bronze the same material?

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).    
Latest company new about Mid Autumn Festival  & National Day Double Holiday Notice

Mid Autumn Festival & National Day Double Holiday Notice

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.  
Latest company new about Macroeconomic Optimism and Policy Support to Continue To Drive Up Copper Prices

Macroeconomic Optimism and Policy Support to Continue To Drive Up Copper Prices

The pressure on the US banking industry has eased and the White House and House Republicans have reached an agreement on the debt ceiling issue. As such, Goldman Sachs lowered its forecast for the probability of a US recession in the next 12 months to 25%, boosting market confidence. Anticipations of a soft landing strengthened. The weekly employment data shows that the US job market is gradually cooling down. As of June 9, according to the CME FedWatch Tool, the probability of the Fed keeping interest rates untouched in June is 71.3%, and the probability of raising interest rates by 25 basis points is 28.7%. The US dollar index is expected to fall and the pressure on copper prices weakened. Eurozone economies cooled down across the board. The GDP of the eurozone in the first quarter continued to decline by 0.1 percentage point from the fourth quarter of 2022, shrinking for two consecutive quarters. That indicates the eurozone has fallen into a technical recession. According to the import and export data released by China, the overseas economic situation is not promising. The export environment has deteriorated, and export orders have decreased significantly. Inflation continued to fall in May, and the downward pressure on inflation is still relatively strong. Affected by the decline in prices of commodities and raw materials, PPI continued to fall in May. The domestic economic recovery slowed down. Exports fell by 7.5% in May, and export orders dropped significantly. After entering the second quarter of the year, the recovery of domestic consumption has slowed down, and export has weakened. In order to boost domestic demand, many places have introduced real estate optimisation policies, and many banks have adjusted deposit rates to provide liquidity for the market. Affected by the positive macro news, copper prices continued to rise. Fundamentally, domestic consumption is relatively resilient. Active dip buying increased new orders while consumption weakened again after SHFE copper prices rose. According to SMM survey, the operating rates at copper rod plants using copper cathode dropped 6.2 percentage points last week as new orders decreased noticeably. A barrage of positive policies will continue to bolster copper prices. Notably, after copper prices rise, new orders will be suppressed. And the support from fundamentals for copper prices will be weak. The most active SHFE copper contract prices are expected to move between 66,000-67,500/mt this week, and LME copper will trade between $8,200-8,550/mt. In China's domestic spot market, SHFE copper inventories fell by 10,000 mt last week, tightening supply. This will further boost sellers’ confidence to raise their quotes. This week, spot premiums will fall to 150-200 yuan/mt before the delivery of the SHFE June contract, and sellers will raise spot premiums to above 400 yuan/mt after delivery.
