磷铜钎焊粉（CuP7) 铜基合金粉

品名铜基合金粉铜含量≥cup7粒度-150m产地长沙

铜磷自钎钎料可以在空气中不需要钎剂的条件下直接钎焊各种铜制元件，广泛应用于制冷设备、压缩机和管道的钎焊。为了提高接口的延展性和导电性可以加入少量的银。

self fluxing copper based brazing alloys containing phosphorusthereby facilitating brazing on copper to copper in air without theuse of a flux. for improved ductility and electrical conductivitysilver containing lower phosphorus alloys also available. widelyused in refrigeration, air conditioning and plumbing industry.
