Corrosion Resistance
The density of aluminium profile shutter is only 2.7g/cm3, which is about 1/3 of that of steel, copper or brass (7.83g/cm3, 8.93g/cm3, respectively). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including in air, water (or brine), Petroleum Chemistry and many chemical systems.
Conductivity
Aluminum profile for shutter is often selected because of their excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminium is nearly twice that of copper.
Thermal Conductivity
The thermal conductivity of aluminium alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, as well as the cylinder head and radiator of automobiles.
Non Ferromagnetism
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 contact with flammable and explosive materials.
Machinability
The machinability of aluminium profile shutter is excellent. In all kinds of deformed and cast aluminium alloys, as well as in all kinds of States after the production of these alloys, the machining characteristics change considerably, 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 has very high recyclability, and the characteristics of recycled aluminium are almost the same as that of primary aluminium.
