In the 1990s, in order to meet the needs of modern war, the lightweight of weapon system has become the trend of weapon equipment development in the world. How to reduce the weight of structural parts designed according to strength index is the key. As an important component, wheel hub is an important part of how to reduce the weight. In the past, the weapon systems used were steel wheels. The steel wheel hub designed according to the strength index has large weight and low fluidity, so aluminum alloy wheel hub has become a better choice.

　　Aluminum alloy wheel hub produced by non casting method and its manufacturing method can reduce the weight of products and improve the mobility. The wheel hub includes aluminum. The weight ratio of elements in the alloy is aluminum 100, copper 1.4-4.8, magnesium 0.4-2.8, zinc 0.3-7, titanium 0.1-0.15, nickel 0.1-1.5.

　　The manufacturing of aluminum alloy wheel hub is controlled within the above composition range. It is melted at 670-720 ℃, filtered by ceramic tube, heated and insulated before forging, forged. In the process of water cooling, the molten metal flows uniformly around the ingot through the casting funnel. When the forging temperature is 420-460 ℃, and the heat preservation is 3-5 hours, the heat treatment is carried out in the vertical quenching furnace.

　　The aluminum alloy wheel hub not only guarantees the performance indexes of the finished wheel, but also greatly reduces the weight of the finished wheel and improves the maneuverability.
