Beryllium bronze

Description:

铍青铜是一种含0.5-3%铍的以及少量镍、铬、钛等元素的铜合金。在完全热处理和冷加工条件下,铜铍是所有铜合金中最硬和最强的(UTS up to 1250~1500MPa)。它结合了高强度、无磁性和无火花特性,在机械性能上与许多高强度合金钢相似,但与钢相比,它具有更好的耐腐蚀性(与纯铜相似)。

Beryllium bronze is a copper alloy containing 0.5-3% beryllium and a small amount of nickel, chromium, titanium and other elements. Under complete heat treatment and cold working conditions, copper-beryllium is the hardest and strongest among all copper alloys (UTS up to 1250~1500MPa). It combines high-strength, non-magnetic and non-sparking characteristics, and is similar to many high-strength alloy steels in mechanical properties, but compared with steel, it has better corrosion resistance (similar to pure copper).

Specification:

Production process:

Raw material smelting → detection → hot rolling → finishing rolling → cutting → clarity → detection → packaging

Application:

它具有良好的导热性和导电性,受冲击时不产生火花,所以这些高性能合金长期以来一直用于采矿(煤矿)、天然气和石化行业(石油钻机)的无火花工具。铍铜螺丝刀、钳子、扳手、冷凿、刀和锤子可用于这些环境。

由于优良的抗疲劳性能,铜铍被广泛用于弹簧、弹簧丝、称重传感器和其他在循环载荷下必须保持形状的零件。

1、 It has good thermal and electrical conductivity, and does not produce sparks when impacted, so these high-performance alloys have long been used in non-sparking tools in the mining (coal), natural gas and petrochemical industries (oil drilling rigs). Beryllium copper screwdrivers, pliers, wrenches, cold chisels, knives and hammers can be used in these environments.

2、Due to its excellent fatigue resistance, copper beryllium is widely used in springs, spring wires, load cells and other parts that must maintain their shape under cyclic loading.
