CA104 (B 2874)

Aluminium Bronze Alloy

CA104 Aluminium Bronze

CA104 is one of the most commonly used aluminium bronzes and is known for its excellent resistance to corrosion and erosion in seawater as well as other chloride containing environments. It is the wrought version of the 10/5/5 aluminium bronze and is usually compared with BS1400 AB2 when a cast alternative is acceptable. CA104 is also known for its high strength and excellent shock and wear resistance whilst being able to retain its properties at cryogenic temperatures.


CA104 offers a good combination of strength and toughness with excellent corrosion and erosion resistant properties. With high wear and abrasion resistance, the alloy also offers excellent property retention at cryogenic temperatures.

Typical Applications

Commercial applications for this engineering material include:

  • High strength fasteners
  • Heavy-duty bushes & bearings
  • Pump components
  • Thrust washers
  • Worm gears
  • Engine components
  • Valve seats

We stock CA104 in flats, round bar, plate, sheet, hollow bar, square bar and hexagon bar.
