Car engine parts come in sturdier, 'green' materials

Manufacturers employ various steel alloys such as tungsten steel for enhanced stability.


  • Upgraded materials: Steel, iron, copper and aluminum are widely utilized. For improved performance, suppliers employ alloy variants of the first metal. Tungsten steel has greater stability and abrasion resistance than cast iron. Used in cylinder liners and pistons, it can endure up to 500 C. A few companies are developing aluminum-silicon alloy engine cylinders that are lightweight and lower energy consumption by 3 to 5 percent.
  • Eco-friendly surface treatment: In line with the ‘green’ trend, more makers add layers of epoxy powder and Dacromet to the coating. Products also undergo deburring and heat treatment, and have zinc plating and matte lacquer finish.
  • OEM shift: To boost sales further, suppliers are enhancing OEM capability by updating production facilities and strengthening QC processes. The categories that cater to this segment include crankshafts, cylinders and liners, pistons and rings and carburetor fields.
  • Wider application: More companies are developing parts for locally made cars such as Chery, JAC and Changan, which posted rapid export growth in recent years. Makers continue to roll out products for Toyota, Honda, Nissan, VW, Peugeot, Volvo and Renault vehicles.
