Sequoia Brass & Copper sells alloy 280 muntz metal. With a chemical composition of 60% copper, 40% zinc and a trace of iron, muntz metal is an alpha-beta brass. Also known as yellow metal, 280 muntz metal is commonly used in architectural projects because it is harder, stronger, and more rigid than other forms of brass.
Common fabrication processes for 280 muntz metal are blanking, forming and bending, hot forging and pressing. Excellent hot working, it's a stronger and "springier" alloy at the expense of a moderate decrease in corrosion resistance. Applications include springs, components of electrical switches and sockets, tubes, plumbing goods and fasteners.
