Lead Alloys and their Uses

Lead alloys containing antimony in the range 1-17 % have the applications noted below  

Arsenic is added to Pb-Sb alloy for age hardening As helps to improve resistance to bending and creep of electric power cable sheathing alloys most widely used alloy is Pb-0.15% As - 0.1% Sn - 0.1% Bi 

In general Cu is added to lead in amounts of up to 0.08% Alloys with addition of Ba, Ca, Co, Au, Li, Mg, Ni, Pt, Na, Ti and Zn have been tested for corrosion resistance anodes made of Ni and Ti give good performance in sulfuric acid solutions Ni in lead improves the weldability of steel during lead coating
