Abstract

The invention discloses an aluminum alloy formula for wheel hub casting, and the aluminum alloy formula for the wheel hub casting is characterized by comprising the ingredients of, in percentage by weight, 3.2-3.8% of silicon, 0.05-0.06% of magnesium, 0.1-0.15% of titanium, 0.08-0.1% of zinc, 0.15-0.30% of strontium and the balance aluminum and a few impurities, and the weight percentage of the sum of all the impurities is less than or equal to 0.2%. By means of the aluminum alloy formula for the wheel hub casting, the defects of an existing aluminum alloy process are overcome, the machined wheel hub is high in intensity and good in corrosion resistance, thermal conductivity and plasticity, and the casting quality is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of casting, in particular to a wheel hub casting aluminum alloy formula. Background technique [0002] Due to its excellent casting performance, good corrosion resistance, high strength-to-weight ratio, low casting manufacturing cost, and near-final molding, cast aluminum alloys are widely used in aviation, aerospace, automobiles, machinery manufacturing, shipbuilding and chemical industries. Has been widely used. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . At present, the commonly used cast aluminum alloys in the market are hard aluminum alloys, which belong to the series of aluminum, copper, and magnesium. They generally con...
