Characteristics Of Aluminum Profiles

Corrosion resistance

The density of aluminum profiles is only 2.7g Cm3, about 1/3 of the density of steel, copper or brass (respectively, 7.83g Cm3). In most environmental conditions, aluminum can show excellent corrosion resistance, including in air, water (or brine), petroleum chemistry, and many chemical systems.


Aluminum profiles are often chosen because of their excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is nearly twice times that of copper.

Thermal conductivity

The thermal conductivity of aluminum alloys is about the $number of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and the cylinder head and radiator of the car.


Aluminum is ferromagnetic, which is an important feature of the electrical and electronic industries. Aluminum profiles are not spontaneous, which is important for applications involving handling or contact with flammable and explosive materials.

Machine processing

The machinability of aluminum profile is excellent. In all kinds of deformed aluminum alloy and cast aluminum alloy, as well as in the various states after the output of these alloys, the machining characteristics vary considerably, which requires special machine tools or techniques.
