Abstract

The invention discloses an aluminum alloy ingot composition for producing a wheel hub. The composition is prepared from, by weight, 3.3-4.1% of zinc, 0.31-0.46% of copper, 2.6-3.2% of magnesium, 6.1-7.3% of iron, 0.6-1.2% of silicon, 0.4-0.9% of manganese, 0.7-1.3% of molybdenum, 0.1-0.7% of platinum, 0.11-0.18% of cadmium, 0.15-0.21% of rhenium, 0.17-0.21% of hafnium, 0.05-0.1% of tantalum, 0.1-0.15% of carbon, 1.1-1.5% of tungsten, 0.35-0.42% of calcium, 0.12-0.16% of nickel, 0.08-0.12% of strontium, 0.03-0.08% of lead and the balance aluminum. According to the composition, under the synergistic effect of all the elements, the stability is high, the deterioration and refinement effect on an aluminum alloy ingot can be achieved, the aluminum alloy ingot with crystal grains which are finerand are more uniformly distributed is obtained accordingly, the aluminum alloy ingot is utilized for producing the aluminum alloy wheel hub, the tensile strength, yield strength and elongation of theobtained aluminum alloy wheel hub are greatly increased, and the aluminum alloy wheel hub has excellent impact toughness and corrosion resistance, good safety and durability.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to an aluminum alloy ingot formula for producing wheel hubs. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. Aluminum alloy is currently the most widely used alloy. [0003] The wheel hub is one of the important parts of the car driving system. The disadvantages of the steel wheel hub are the heavy weight, large inertial resistance, poor heat dissipation, and very easy to rust. The alloy wheel hub can just make up for this problem. It has light weight, small inertial resistance, hi...
