The invention relates to a manufacture method for aluminum alloy hub alloy that contains Al 100, Cu 3.9-4.8, Mg 0.4-0.8, Zn 0.3, Ti 0.15 and nickel 0.1. The method includes the following steps: smelting in 670-720 degree centigrade; filtering by ceramic tube, heating and preserving before forging, forging, making the metal liquid flow to the round of the ingot casting equally by funnel; forging temperature is 420-460 degree centigrade and temperature preserving time is 3-5 hours, forging and fdie forging, taking heat treatment in standing hardening furnace. The invention could be used as aluminum alloy hub.
Description
technical field [0001] The invention relates to an aluminum alloy hub material for a machine wheel and a manufacturing method thereof. Background technique [0002] In the 1990s, in order to meet the needs of modern warfare, the lightweight of weapon systems has become the development trend of weapons and equipment in all countries in the world. How to reduce the weight of the structural parts designed according to the strength index is the key. As an important component, how to reduce weight is the most important thing. The weapon system used in the past is made of steel. The steel wheel designed according to the strength index is heavy in structure and low in maneuverability. It cannot be better. adapt to the needs of modern warfare. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the weapon system used in the past is made of steel, and the steel wheel designed according to the strength index has a heavy structure an...
