Friction & Braking

A sintered friction lining is a metal matrix engineered to wear predictably under heat and load. Copper and bronze powders form the thermally conductive matrix that carries heat away from the friction surface, iron powder adds hardness and structural strength, and the ratio between them tunes the friction coefficient and wear rate of the finished pad or facing. Consistency between batches is critical: a shift in particle size or apparent density changes compaction behaviour and, ultimately, braking performance.

Irregular and sponge morphologies dominate friction applications because their interlocking particle structure gives the green strength and compressibility needed to press linings that hold together before sintering. Reduced iron grades between -100 and -325 mesh are the standard backbone, with copper and bronze additions blended to the manufacturer's own formulation. Ronald Britton supplies all three material families, with stock grades marked in each metal's grades table.
