Reasons Affecting The Quality Of Aluminum Housing

The aluminum shell is produced and cast under high temperature conditions. The production speed of aluminum shell is too fast and the cooling intensity is relatively large, which causes some elements in the alloy to be unable to transform into the required elements within the specified time. Because this material has needle-like structure and relatively high hardness, poor plasticity. Moreover, the tensile strength of this manufacturing process is very low, and not only will yellow rust appear under high temperature conditions, but also cracks will appear. The aluminum shell produced in this way will have granular burrs. If this burr is not cleaned, it will have a very poor hand feeling. Such particles are often accompanied by tadpole-like tails, which will be observed under a microscope. And the color of this impurity is gray and contains a lot of iron.
