Aluminium typically plays a key role in reducing the weight of a car which also helps to reduce fuel consumption. A modern car contains large amounts of aluminium and use of the metal is on the increase.
A new casting technology makes it possible to cast aluminium bolts with small diameters and high-quality surface properties which enables the metal to be used directly in the manufacture of parts such as suspension components in cars.
By using cast material, the production of aluminium car components becomes less expensive, more eco-friendly and more efficient, while also reducing the amount of production scrap generated.
The casting technology has been developed by the Norwegian aluminium producer Hydro and is carried out under vacuum conditions.
Currently, a car component production line is made up of several production steps, including casting, heat treatment, extrusion and the subsequent forging/shaping process that ensures that the final product...
