It is a good elastic material in copper alloy, with a series of high strength, elasticity, hardness, fatigue strength, small elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetism, impact and no spark Excellent physical, chemical and mechanical properties.
When casting in an iron mold with high casting temperature, fast casting speed, and low cooling rate, it promotes component segregation. In addition, when gas is precipitated during the solidification process, primary crystals with a lower density can also be used to float with the gas. High-performance beryllium bronze has a hardness between (HRC) 38-43, a density of 8.3 g / cm3, and a beryllium content of 1.9% -2.15%. Cooling systems, thermal nozzles, integral cavities for blow molds, automotive molds, wear plates, etc.
This is related to the cooling rate of the alloy, the density, shape and size of the primary crystal, and the casting process. The smaller the cooling rate, the smaller the density of the primary crystals, the larger the size, and the greater the relative movement speed of the liquid and the solid, the better the moon is for the floating of the primary crystals.
