The circle cast iron with spiny surface is inserted by aluminum, provides a strong adhesion with aluminum and high heat transfer to aluminum.

Expectable Effect

  1. Light weight: Compare with the present brake drum made of cast iron (1.5L class),weight is reduced about 35%.
  2. Improved cooling : Heat transfer is better than the present product.
  3. Improved roundness: Effect is in reduction of brake noise and judder.
