C31400 Leaded Commercial Bronze

C31400 leaded commercial bronze maintains the corrosion resistance of other bronzes but also has better machinability. It works well in situations where corrosion can happen, but you don't need high strength.

C31400 is used in electrical, construction, and industrial industries. Common applications include:

  • C31400 Leaded Commercial Bronze Cable and Wire Connectors
  • C31400 Leaded Commercial Bronze Doorknobs
  • C31400 Leaded Commercial Bronze Fasteners
  • C31400 Leaded Commercial Bronze Pickling Crates, Racks, & Fixtures
  • C31400 Leaded Commercial Bronze Screw Machine Parts

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

Technical Details

C31400 is made up of 89% copper, 9.25% aluminum, and 1.75% iron. The best welding techniques include:

  • Brazing
  • Butt
  • Soldering
