80/20 Red Brass Wire
Red Brass with a nominal composition of 80 % copper and 20 % zinc approaches the mechanical properties of CuZn30 but with corrosion properties only slightly inferior to CuZn15. This alloy has a color between yellow and golden red and finds distinctive uses in decorative trim applications. Its color and tonal qualities prove advantageous for musical instruments. Thermostatic and instrument bellows and flexible hose utilize the combined ductility, strength and corrosion resistance characteristics of this alloy.
Typical Uses :
Architecture: medallions, ornamental components, spandrels Builders Hardware: decorative panels Consumer: clock dials, musical instrument parts, plaques Electrical: battery caps, rotor bars for AC motors Industrial: flexible hose, flexible hose bellows, pump lines, welding wire other tokens.
