BS EN 1982-2008 GC CC481K
This is a continuously cast copper based alloy containing 10.2-11.5%Sn. It conforms to BS EN 1982-2008 CC481K
CuSn11P-C and can be supplied to BS1400 PB1 CuSn10P.
This alloy combines high mechanical strength with good ductility, corrosion resistance and wear resistance. It also offers a good resistance to shock loading but is out performed in this area by the wrought grades.
PB1 can be soldered and brazed and is traditionally used in heavy load applications run at high speed with adequate lubrication.
