Description

Material CuSn5, mat. No. CW451K is used in the form of tubes for manometer springs or hose tubes as well as for contact springs and connectors. Basically the same application area as CuSn6 (CW452K). CuSn5 shows slightly higher electrical conductivity at slightly lower strength due to the lower tin-content. For the electrolytically tinned strip the coatings (Sn bright, Sn matt, Sn fuzed, SnPb) are listed by the application (better solderability, better corrosion resistance, reduction of the electrical contact resistance, better appearance) in the DIN EN 14436 : 2004-11 (Table 5)
