Abstract

PURPOSE:To arbitrarily regulate the coefft. of thermal expansion of a magnetic Al composite material while maintaining the desired magnetic characteristics, by blending powder of a ferromagnetic body with Al (alloy) powder and powder of a metal for regulating the coefft. of thermal expansion so as to satisfy prescribed equalities and by molding the resulting mixture. CONSTITUTION:The blending rate of powder of a ferromagnetic body is set according to the desired magnetic performance. Vf vol.% of the powder is blended with Va vol.% Al (alloy) powder and Vz vol.% powder of a metal for regulating the coefft. of thermal expansion so as to satisfy equalities Af.Vf+Aa.Va+Az.Vz=A-0.2-A+0.2 and Vf+Va+Vz=100 [where A is the desired coefft. of thermal expansion of a produced Al composite material, Af is the coefft. of thermal expansion of the ferromagnetic body, Aa is the coefft. of thermal expansion of the Al (alloy) and Az is the coefft. of thermal expansion of the metal for regulating the coefft. of thermal expansion]. The resulting mixture is press-molded.
