摘要：
A metal composition comprising zinc oxide whiskers dispersed in a metal matrix. The whiskers comprise at least one needle crystal having a basal part whose diameter is from 0.7 to 14 micrometers and a length from the basal part to its tip of from 3 to 200 micrometers. The metal composition is isotropically reinforced with respect to mechanical strength and is significantly improved in free cuttability.
