WONDER beryllium bronze copper alloy is a kind of elastic material with high performance, high strength, elasticity, hardness, fatigue strength, small elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high electrical conductivity, non-magnetic, impact does not produce sparks, etc. Excellent physical, chemical and mechanical properties, it is widely used as an important elastic element, wear-resistant parts and explosion-proof tools. Beryllium bronze contains 1.7 to 2.5% beryllium and a small amount of nickel, chromium, titanium and other elements. After quenching and aging treatment, the strength limit can reach 1250 to 1500 MPa, which is close to the level of medium strength steel. It has good plasticity in the quenched state and can be processed into various semi-finished products.
Using metallography, scanning electron microscopy and electron probe analysis to analyze the cracking phenomenon of the beryllium bronze rod during the forging process. The results show that the cracking of the beryllium bronze rod is caused by the presence of more copper, calcium oxides and sulfides in the forging billet raw materials. Raw material of forging billet is the key element to control the forging quality of beryllium bronze rod.
Beryllium bronze (also known as beryllium copper alloy) is a typical precipitation-strengthened high conductivity, high elasticity copper alloy. The editor of Dongguan Aluminum Bronze Factory stated that in addition to its advantages of high elasticity, strength, hardness, wear resistance and fatigue resistance, it also has excellent electrical conductivity, thermal conductivity, corrosion resistance, high and low temperature resistance, and no magnetism. , It does not produce sparks during impact, and is one of the important materials with good comprehensive performance in the industry. It is widely used as various elastic elements, commutation switches, electrical contactors, wear-resistant parts, and when used in mines and petroleum plants. Non-sparking tools, etc.
Beryllium bronze has good forging performance, and it is easy to produce workpieces of good size, good quality and sufficient aging strengthening through hot processing. The forging process has a strong adaptability to the manufacture of workpieces with large changes in shape and size, so it has become one of the indispensable important methods for processing beryllium bronze. However, because the beryllium copper alloy often cracks in the center and surface during the actual forging production process, it is difficult to continue processing or lead to a significant decrease in the yield rate.
WONDER is committed to creating high-quality and low-cost materials for the public. Global supply of beryllium bronze C17200, chromium zirconium copper C18150, beryllium nickel copper C17510, beryllium cobalt copper C17500, aluminum bronze, beryllium cobalt nickel and other materials.
