BZn15-20锌白铜#结构铜镍合金
BZn15-20锌白铜#结构铜镍合金
BZn15-20 argentan to structure of copper and nickel, alloy its appearance is beautiful silvery white, commonly known as deutsche bank (was Chinese silver), BZn15-20 white copper with high strength and corrosion resistance, good plasticity, under hot and cold are machined well under pressure, but poor machinability, poor weldability, elasticity is better than that. QSn6.5-0.1. Cupronickel BZn15-20 structure used in damp, working parts and instrument parts in corrosive environment, medical equipment, telecom parts, artwork, spring tubes, etc.
BZn15-20锌白铜为结构铜镍,合金其外表具有美丽的银白色,俗称德银(本来是中国银),BZn15-20锌白铜具有高的强度和耐蚀性,可塑性好,在热态及冷态下均能很好地承受压力加工,可切削性不好,焊接性差,弹性优于。QSn6.5-0.1。BZn15-20结构白铜用于潮湿,腐蚀环境中工作的零件及仪表零件,医疗器具,电讯零件,艺术品,弹簧管等。
