Aluminum alloy shell
The aluminum alloy housing has the following features:
1. Corrosion resistance
The density of aluminum profile is only 2.7g/cm3, about 1/3 of that of steel, copper or brass (7.83g/ cm3 and 8.93g/ cm3 respectively). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including air, water (or brine), petrochemicals, and many chemical systems.
Aluminum profiles are often used because of their excellent conductivity. On the basis of equal weight, the conductivity of aluminum is nearly twice that of copper.
3. Thermal conductivity
The thermal conductivity of aluminum alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.
Aluminum profiles are non ferromagnetic, which is an important characteristic for the electrical and electronic industries. Aluminum profiles cannot spontaneously ignite, which is important for applications involving handling or contacting flammable and explosive materials.
The machinability of aluminum profiles is excellent. In a variety of wrought and cast aluminum alloys, as well as in various states after the production of these alloys, the machining characteristics change considerably, which requires special machine tools or technologies.
Specific tensile strength, yield strength, ductility and corresponding work hardening rate control the variation of allowable deformation.
