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
- Wake 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
