Brass Pipe Lead Content

Brass pipe lead content indicates the brass pipe containing lead content. To enhance the machinability of brass, lead is often added in concentrations of around 2%. Since lead has a lower melting point than the other constituents of the brass, it tends to migrate towards the grain boundaries in the form of globules as it cools from casting. The pattern the globules form on the surface of the brass increases the available lead surface area which in turn affects  the degree of leaching.
