Muntz Metal (C28000 or C280) was founded and patented in 1832 by English businessman George F. Muntz. One of the most diserable features of Muntz metal is it's distinctive color. This particular metal is primarily used in architectural applications. Muntz metal is a highly plastic metal at red heat, making it an ideal choice for pressing, stamping and hot forging. Other advantages that C280 lends are: high ductility, high electrical and thermal conductivity, high impact strength, good creep resistance, ease of welding, and low volatility under high vacuum.

Typical Applications:

Architectural applications
Decorative Hardware
Condenser plates
Heat Exchanger Tube
Valve Stems
Brazing Rod
