Title: Partially composite lightweight metal product and preform for producing thesame

Abstract: A porous preform for manufacturing partially composite lightweight metalproducts including at least a sliding surface as composite part is made ofa hard material which comprises a sintered mixture comprising TiO.sub.2particles, short ceramic fibers and whiskers, and SiC particles having anaverage particle size of approximately 20 to 100 .mu.m. The partiallycomposite lightweight metal product produced from the porous preform isprovided with superior wear resistance and high strength and achievesincreasing the coefficient of friction even though it is large in size, soas to keep a composite part of the composite lightweight metal productsuch as a sliding surface of a brake rotor remain even and smooth for along period of time.
