The density of aluminum shell processing is only 2.7g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83g/cm3, 8.93g/cm3, respectively). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including in air, water (or brine), petrochemicals, and many chemical systems.
The machinability of the aluminum case processing is excellent. In various wrought and cast aluminum alloys, and in the various states in which these alloys are produced, the machining characteristics vary considerably, which requires special machine tools or techniques.
Aluminum housing machining is often chosen due to its excellent electrical conductivity. On an equal weight basis, aluminum has nearly twice the electrical conductivity of copper.
The thermal conductivity of aluminum alloys is about 50-60% of that of copper, which is beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.
The complexity of the cavity lies in what the material is used for. It is also determined according to the accessories that can be compatible with it. As for the mechanical strength involved, there are also considerations in this regard. It is nothing more than an increase in the material wall thickness and an extra side of the reinforcing rib.
The formation of shrinkage cavities is due to the destruction of the directional sequential solidification of the aluminum alloy liquid, and the solid phase surrounds a small part of the liquid phase, so that the surrounding area cannot get enough aluminum to supplement the alloy liquid.
Aluminum also has an extremely low thermal emissivity. Excellent thermal properties such as these make aluminum an excellent vacuum material. The surface properties of aluminium allow the aluminium vacuum chamber to be fully baked at 150oC.
