X大管铝白铜【QAL9-4】抗氧化铜材QAL9-4铝白铜
QAL7 aluminum bronze characteristics and scope of application: use and QAl5 similar performance, due to the aluminum content is a bit high, its strength is higher. Do not contain other elements of aluminum bronze, has high strength, flexibility and wearability, in the atmosphere, fresh water, sea water, and some acid high corrosion resistance, electric welding, gas welding, brazing, well under cold or hot processing under pressure, cant quenching tempering reinforcement.
QAL7铝青铜特性及适用范围:性能用途和QAl5相似,因含铝量稍高,其强度较高。
不含其他元素的铝青铜,有较高的强度、弹性和耐磨性,在大气、淡水、海水和某些酸中耐蚀性高,可电焊、气焊、不易钎焊,能很好地在冷态或热态下承受压力加工,不能淬火回火强化。
