Abstract
Abstract In construction of a composite material for decorative applications such as eyeglass frames, adjusted addition of whiskers to metal matrix provides the product with light weight, rich anticorrosion, high strength and, rich elasticity. Additional core-to-sheath cladding further improves workability without any influence on the light weight characteristics.
