DBA develops XG-150

After 30 years of design and development with race teams worldwide, Disc Brakes Australia (DBA) developed a proprietary cast iron formulation (XG-150) for use in all of its premium performance disc brake rotors.

DBA's grey iron is rich in carbon and alloyed to produce excellent thermal characteristics, which is a key factor in the production of the casting. This is combined with our patented Kangaroo Paw ventilation design.

With a supersaturated solution of carbon in an iron matrix, the excess carbon precipitates out in the form of graphite flakes. The structural distribution of these graphite flakes provide excellent thermal properties, increasing the thermal shock resistance.

Additionally, when combined with DBA's TSP process it allows the material to cope with rapid thermal cycling with core-heat levels reaching approximately 700°C and above.

The DBA developed the TSP™ process, stress relieves the cast iron during the manufacturing process. Unlike any other cast irons, the XG-150 formulation was developed to respond to the TSP process, resulting in a rotor that is ideal for heavy-duty braking and suitable for motorsport applications.
