Now in our product range: Forged Aluminum Bronze

Our company is currently stocking a wide range of semi-finished products made from forged aluminum bronze, such as CuAl10Ni5Fe4 (CW307G), as well as other alloys. Our inventory includes round bars, hollow bars, square bars, flat bars, hexagonal bars, and plates/sheets, which find many industrial applications.

Why Choose Forged Aluminum Bronze?

Forged aluminum bronze is known for its exceptional mechanical properties and versatility. Aluminum bronze alloys typically contain approximately 10% aluminum, 5% nickel, and 4% iron to achieve desired properties such as:

  • High strength, load resistance, and wear resistance (friction)
  • Excellent corrosion resistance (even in saltwater)
  • Good machinability for creating high-quality finished products

Common Uses of Our Semi-Finished Products

Our semi-finished products are used in the manufacture of:

  • Marine equipment (propeller shafts, pump and valve components that require excellent corrosion resistance)
  • Industrial machinery (bearings, bushings, and gears, valves)
  • Aerospace components (due to the good strength-to-weight ratio)
  • Electrical connectors (for their good conductivity and high durability)

The Forging Process of Aluminum Bronze

The production of forged aluminum bronze involves these key steps:

  1. Heating: The aluminum bronze alloy is heated to a temperature above its recrystallization point, typically over 927°C, to make it malleable.
  2. Forging: The heated alloy is then subjected to compressive forces using forging presses or hammers. This process refines the grain structure, improving the metal's mechanical properties.
  3. Annealing (optional): To further improve the alloy's ductility and relieve internal stresses, the forged aluminum bronze may undergo an annealing process. Annealing involves heating the alloy to a specific temperature and then slowly cooling it down, resulting in a more uniform microstructure and increased machinability.
