7075 aluminum plate is known as high strength and high hardness of the aluminum plate, in addition to the application in the aerospace field, actually can also be used in the automobile industry, car industry has used 6061 aluminum plate as a hub, if demand is high, also can use 7075 aluminum as raw materials, the next 7075 aluminum manufacturers to introduce to everyone, 7075 aluminum wheel production technology.

The 7075 aluminum plate hub mainly adopts two technologies of casting and forging:

Casting: Low pressure casting is a common method to produce 7075 aluminum plate wheel hub, which is also more economical.Low pressure casting molten metal is cast and solidified in a mold.Low pressure casting is to use a very strong vacuum to suck the metal into the mold, maintain constant temperature and remove impurities. There is no porosity in the casting and it has uniform density distribution and high strength requirements.

Forging: Forging is a more advanced method of making 7075 aluminum plate wheels by pressing an aluminum ingot into the hub at a pressure of 62.3Mn in a thermal state.For example, the aluminum wheel hub 7075 is three times as strong as the average aluminum wheel, but the former is 20% lighter than the latter.Beautiful shape and complex structure of the hub, it is impossible to forge one can be formed.Roll forging (also known as forging) is forging, rough forging rolling hub.While the strength of the hub is constant, the thickness of the material can be reduced.The 7075 aluminum plate hub produced by this process not only has uniform density, smooth surface, thin ring wall, light weight, but also can withstand greater pressure.However, as the product requires more sophisticated production equipment and the production rate is only 50%-60%, the manufacturing cost is slightly higher and the price is not low.

The above is about the production technology introduction of 7075 aluminum plate wheel hub. If you need 7075 aluminum plate, please contact us.
