Bronze CUSN6
Different names for CuSn6 :
- German (DIN): CuSn6
- France (Afnor): CuSn6P
- Europe (EN): CW452K
- ASTM : C51900
CuSn6 and its properties :
CuSn6 has several properties common to all bronzes such as high mechanical and electrical characteristics. CuSn6 has good electrical conductivity, wear resistance and resistance to industrial atmosphere. It is also resistant to seawater and is largely insensitive to stress corrosion cracking.
It has a very good cold deformation and average deformation when hot. It has good machining, welding and brazing capabilities.
The bronze CuSn6P can be used instead of brass in the vacuum technique. See technical data sheet for CuSn6 bronze.
