Muntz Metal and Naval Brass are copper alloys composed of 60% copper and 40% zinc. They have a rich golden color and are widely used architectural community for elevator cabs, entrances, revolving doors, swing doors, and storefront just to name a few.

All copper based alloys have a tendency to tarnish with age. Tarnishing is caused by oxidation from exposure to air. In order to keep them looking good, it's necessary to clean off tarnish and polish your objects as needed. Many customers choose to lacquer their brass/bronze products to keep them from tarnishing.
