Extended data
Characteristics of aluminum profiles:
1, corrosion resistance
The density of aluminum profile is only 2.7g/cm3, which is about 1/3 of steel, copper or brass (7.83g/cm3 and 8.93g/cm3 respectively). In most environmental conditions, including air, water (or salt water), petrochemical and many chemical systems, aluminum can show excellent corrosion resistance.
2. Conductivity
Aluminum profiles are often chosen because they have good electrical conductivity. On the basis of the same 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, cookers, cylinder heads and radiators of automobiles.
4. Non-ferromagnetic
Aluminum profiles are non-ferromagnetic, which is an important feature of electrical and electronic industries. Aluminum profiles can't spontaneously ignite, which is very important for handling or contacting flammable and explosive materials.
5. Machinability
The machinability of aluminum profiles is very good. In all kinds of wrought aluminum alloys and cast aluminum alloys, and in all kinds of States after these alloys are produced, the machining characteristics change greatly, and special machine tools or technologies are needed.
6. Formability
Specific tensile strength, yield strength, ductility and corresponding work hardening rate determine the variation of allowable deformation.
7. Refolding
Aluminum is highly recyclable, and the characteristics of recycled aluminum are almost the same as those of primary aluminum.
