Steel composite brake disc product technology

Steel composite brake drum: Invention patent number: ZL201210061027.2

Steel composite brake disc product technology

Lighter and Stronger

The FLANGE comprises of high strength and high resilience material, offering a 15-25% weight savings while maintaining the strengh properties

Eliminating neck crack

The NECK is a single form process made from high yield strengh material,eliminating neck cracking


The petal structure connection allows for rapid two-way cooling airflow,radial and axial airflow reducing excessive heat build-up

Heat transmission

The reduced connection surface between NECK and FLANGE allows for considerable heat transmission reduction.This reduces heat transmission to the Bearings,Lubricant,Wheel Rims and TYres.
