C62300 Aluminum Bronze Alloy

C62300 aluminum bronze is a wrought alloy. It is notable for its high wear and corrosion resistance, and it also has high strength, resists acid, and is non-sparking.

C62300 is often used for fasteners and in industrial applications. Common applications include:

  • Bronze Bearing Races
  • Bronze Bearings
  • Bronze Bushings
  • Bronze Cams
  • Bronze Nuts & Bolts
  • Bronze Pump Rods
  • Bronze Valve Stems
  • Bronze Worm Gears

Diversified Bronze has solid and cored C62300 aluminum bronze bars in 144" lengths. Other lengths and non-standard sizes are available.

Technical details

C62300 is made up of 82.2-89.5% copper, 8.5-11.0% aluminum, and 2.0-4.0% iron. The best welding techniques include:

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