Bronze definition: with Be ≤ 2.5% beryllium copper binary alloy, in addition to high strength, elasticity, hardness, wear resistance and fatigue resistance, there are good electrical conductivity, thermal conductivity, corrosion resistance, non-magnetic, shock does not produce sparks, and a good process performance. Widely used in the manufacture diaphragm, diaphragm, spring tube, springs and other elastic components. With wear? Low temperature, non-magnetic, high electrical conductivity, impact no sparks and so on. It also has good mobility and the ability to reproduce fine patterns. Because of the many advantages of beryllium copper alloys can make it in the manufacturing sector gained wide application. 
 Bronze grades: 
 1 China: QBe2, QBe1.7 
 (2) United States (ASTM): C17200, C17000 
 3 U.S. (CDA): 172, 170 
 4 Germany (DIN): QBe2, QBe1.7 
 5 Germany (digital system): 2.1247, 2.1245 
 6 Japan: C1720, C1700 
 The use and performance of high-performance bronze bronze hardness (HRC) 38-43 between the density 8.3g/cm3, beryllium-containing 1.9% -2.15%, which is widely used in plastic injection molding inserts within the mold, the mold core , die punch, hot runner cooling system, heat the mouth, the overall cavity blow mold, automobile mold, wear plate and so on.
