Muntz 280 is a copper alloy with a nominal composition of 60% copper and 40% zinc. Also known as muntz metal, it has a bright gold color and is preferred for many commercial applications because it is harder than bronze. Bronze 220 alloy has a nominal composition of 90% copper and 10% zinc. Sometimes called commercial bronze, it has a deeper red appearance than muntz. Our standard is to apply a polyurethane clear coat to both materials to minimize color change. If requested, the factory will omit the clear coat for antique or oil-rubbed finishes to be applied by others.
