Aluminum processing
- Jan 23, 2018 -

Aluminum and aluminum alloy plastic processing, should ensure that products to achieve stable, consistent dimensional accuracy, mechanical properties and good surface quality. Also pay attention to prevent mechanical damage and corrosion, control grain size and texture. These quality requirements mainly rely on the production process and equipment to ensure. Aluminum and its alloys generally have good ductility and are easy to plasticize. The phase composition of hard aluminum is more complex, there are brittle structures such as low melting phase and intermetallic compounds, and its plastic processing has some characteristics: such as homogenization to eliminate the internal stress and intragranular segregation generated when the billet cools; billet Milling the surface to be processed, remove the surface segregation of low-melting-phase. Some aluminum alloys are also coated with aluminum to improve corrosion resistance and workability. Aluminum alloy has overheating sensitivity, must be strictly controlled heating temperature.
