CC495K /CuSn10Pb10

Leaded tinbronze.

Due to the high lead (Pb) content and a decreasing demand, we no longer stock this alloy. CuPb10Sn10 is normally replaced by alloy Rg7, which is an alloy with similar characteristic and performance despite lower lead-content.

Leaded tinbronzes are still available – in limited size-range – and can be offered or supplied upon request.

This goes for CuPb10Sn as well as CuPb15Sn which is the standard outside Scandinavia.
