C36500 Leaded Muntz is copper, alloyed with zinc, tin and lead. Muntz metal has strength and corrosion resistance similar to C46400 Naval Brass but the higher lead content results in better machinability. C365 Muntz metal found historical prominence in the shipbuilding industry, primarily as a hull liner. C36500 Leaded Munts was adopted by the pressure vessel industry and is still, for many manufactures, the preferred alloy for tubesheets and condenser/cooler plates. Because of its warm reddish gold hue and corrosion resistance, 365 Muntz also has numerous decorative and architectural applications.
