Product Description
C28000 Muntz MetalFounded and patented by English businessman George F. Muntz in 1832, Muntz Metal (C28000 or C280) is primarily used in architectural applications owing to its distinctive color. It is highly plastic metal at red heat that makes it ideal for pressing, stamping and hot forging. The metal alloy is also appreciated for high electrical and thermal conductivity, high ductility, high impact strength, good creep resistance, ease of welding, and low volatility under high vacuum.
