ABSTRACT:
Thin automobile components, such as a transmission case made of an aluminum alloy, are provided which are less likely to create vibration-derived noise. An aluminum alloy member, with an insert provided therein, possessing improved damping capacity, comprising: an austempered graphite cast iron member inserted into an aluminum alloy with the thickness of a section constituting a product being not more than 6 mm. A process for producing an aluminum alloy member, with an insert provided therein, wherein cooling is performed so as for the temperature of a graphite cast iron material to reach 400.degree. C. or below within 10 sec after pouring of an aluminum alloy. The graphite cast iron material comprises by weight 2.5 to 4.0% of carbon, 2.0 to 3.5% of silicon, 0.1 to 0.8% of manganese, and at least one member selected from the group consisting of 0.1 to 2.0% of copper, 0.1 to 2.0% of nickel, and 0.05 to 0.5% of molybdenum with the balance consisting of iron and unavoidable impurities. The aluminum alloy comprises by weight 2.0 to 4.0% of copper, 7 to 12% of silicon, and not more than 0.3% of magnesium with the balance consisting of aluminum and unavoidable impurities.
