60/40 Brass Sheet – CuZn40

Founded and patented by English businessman George F. Muntz in 1832, Brass Sheet (C28000 Brass Sheet or C280 Brass Sheet) 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 Pressure.

Application Areas:

• Architectural Panels
• Large Architectural Trim
• Structural Sheets
• Door Frames
• Decorative Hardware
• Condenser Plate
• Heat Exchanger Tube
• Valve Stems
