Characteristics of aluminum profiles

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 in air, water (or brine), petrochemicals, and many chemical systems.

conductivity

Aluminum profile is often selected because of its excellent conductivity. On the basis of equal weight, the conductivity of aluminum is nearly 1 / 2 of that of copper.

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, cylinder heads and radiators of automobiles.

Non ferromagnetism

Aluminum profiles are non ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles are not self ignited, which is important for applications involving handling or contacting flammable and explosive materials.

Processability

The machinability of aluminum profile is excellent. In all kinds of wrought and cast aluminum alloys, as well as in the various states after the production of these alloys, the machining characteristics change greatly, which requires special machine tools or technologies.

Formability

Specific tensile strength, yield strength, ductility and corresponding work hardening rate control the variation of allowable deformation.

Recyclability

Aluminum is highly recyclable, and the properties of recycled aluminum are almost the same as that of primary aluminum.
