C89833 Alloy Casting

Copper-Bismuth Sand Cast Alloy C89833

From January 14, 2014, all brass products used in potable water installations must be lead-free. This material has been qualified for use in plumbing fittings and valves. C89833 is a bismuth tin bronze alloy with excellent machinability. It offers the same strength and corrosion resistance as traditional bronzes while reducing hazardous elements like lead. These attributes make it an excellent choice for drinking water safety applications. Copper-bismuth C89833 has a copper content of not less than 86%. 

Benefits of C89833
• Excellent machinability
• Cost-effective manufacturing process
• Strength and corrosion resistance as traditional bronzes
• Reduced levels of toxic metals such as lead
