C62400 Aluminum Bronze Alloy

C62400 aluminum bronze is a wrought alloy. It has good strength and high corrosion resistance, and heat-treating improves these properties.

C62400 is often used as fasteners or in marine and mechanical applications. Other typical applications include:

  • Bronze Bushings
  • Bronze Cams
  • Bronze Drift Pins
  • Bronze Gears
  • Bronze Hydraulic Bushings
  • Bronze Support Bushings
  • Bronze Tie Rods
  • Bronze Valve Balls
  • Bronze Wear Plates
  • Valve Welding Wire

Diversified Bronze has solid and cored C62400 aluminum bronze bars in 144" lengths. Other lengths and non-standard sizes are available.

Technical details

C62400 is made up of 82.8-88.0% copper, 10.0-11.5% aluminum, and 2.0-4.5% iron. The best welding techniques include:

  • Brazing
  • Butt
  • Coated-Metal Arc
  • Gas-Shielded Arc
  • Seam Welding
  • Spot Welding
