In the CNC machining of aluminum alloy shell, it is widely used in the electronics industry with its characteristics of convenient processing, high flexibility and high grade. So, what are the advantages of aluminum alloy shells in CNC machining?
The excellent characteristics of aluminum alloy are good appearance, light weight, machinability, good physical and mechanical properties, and good corrosion resistance. As a result, aluminum is considered the most economical and practical material for many applications.
The density of aluminum is only 2.7 g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83 g./cm3 and 8.93 g/cm3, respectively). Excellent corrosion resistance under most environmental conditions.
The surface of aluminum is highly reflective, and radiant energy, visible light, radiant heat, and radio waves are all effectively reflected by aluminum. Anodized and dark anodized surfaces can be reflective or absorbent.
Aluminum has excellent electrical and thermal conductivity. On the same weight basis, aluminum conducts electricity almost twice as much as copper. The thermal conductivity of aluminum alloys is about 50%-60% that of copper, which is beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cookware, as well as cylinder heads and radiators for automobiles. Aluminium is non-ferromagnetic, which is an important property in the electrical and electronics industry. Aluminum does not spontaneously combust, which is important for applications involving handling or exposure to flammable and explosive materials. Aluminum is non-toxic and is commonly used in food and beverage containers. And its natural surface state has a pleasant appearance, which can be oxidized and plated into different colors.
