Why Aluminum-Silicon Products Are Preferred in the Automotive Industry

Aluminum-silicon products have been widely used in the automotive field.
Their special properties make them highly suitable for many car parts.

Main Reasons for Their Use

Lightweight and Strong

  • Aluminum-silicon is made of 90% aluminum and 10% silicon.

  • A low density is achieved, making the material very light.

  • High plasticity and ductility are required for auto accessories.

  • Parts such as rods, sheets, foils, powders, strips, and wires are easily made.

Excellent Processing Ability

  • Aluminum-silicon can be easily stamped and pressed into shapes.

  • Car parts like exhaust pipes, fuel tanks, and fittings are often made from it.

  • The material’s ease of forming is a key advantage.

High Temperature Resistance

  • An iron-aluminum alloy is formed between the steel plate and the coating.

  • Strong resistance to high temperatures is shown.

  • Reflectivity remains high at 450°C.

  • A gray coating appears at 480°C but stays protective.

  • At 650°C, the protective layer remains intact with no shedding.

Outstanding Corrosion Resistance

  • During hot-dip plating, a protective Al₂O₃ layer is formed immediately.

  • This layer passivates the surface and does not dissolve in water.

  • Even if scratched, the surface heals itself.

  • Strong resistance to chemical corrosion is provided.

Environmental Benefits

  • Aluminum-silicon production is green and eco-friendly.

  • National rose certification standards are met.

  • New energy vehicles increasingly demand such environmentally safe materials.
