The lead is not a very common material in the die cast industry, but thanks to his high density, it is a properly solution where the space for the parts is critical and high weight is request. Density is 11,4 gr./cm3.
It is a very moldable material and allows having very complex forms in the pieces.
Normally we use lead alloys with 3%-4% Sb, where we obtain very high productivities.
Another important specification of the lead is that has a very long-live, where normally is not requested any treatment.
In alloy with others elements like: Sn, Sb, Ca etc. Improve his mechanicals properties.
It’s most common use is usually as ballasts in the automotive industry, battery terminals, but has applications in nuclear power plants or as a covering in radiators.
Despite what people might think, is a 100% recycle material and melted in his correct temperature does not produce pollutant emissions.
