Typical materials: ADC12 and various grades of aluminium

Aluminium is the most abundant metal found on Earth. Aluminium products are weather-proof, corrosion-resistant, and last a very long time. They are strong despite being fairly lightweight.

ADC12 aluminium alloy has high mechanical properties and very good castability. This alloy is mostly used to manufacture automobile parts with complicated shapes like transmission cases, cylinder blocks, and converter housings. It is also used for frames and front panels.

Benefits include:

  • Ease of casting
  • Corrosion-resistance
  • Good mechanical properties
  • Dimensional stability
  • Lightweight

Material composition

  • 2% to 3% Copper
  • 1.3% Iron
  • 9.5% to 11.5% Silicon
  • 3% Zinc
  • 0.5% Manganese

Common MOQ: 500 to 10,000 pcs

Manufacturing methods: Casting, forging, and die casting

  • Once the components have been produced, the manufacturer will machine the components to match your exact specifications
