Characteristics of aluminum profile
The density of aluminum is only 2.7g/cm3 about the density of steel, copper or brass (7.83g/cm3,8.93g/cm3 respectively), 1/3. In most environments, including in air, water (or salt water), petrochemicals, and many chemical systems, aluminum can show excellent corrosion resistance.
Aluminum is often used due to its excellent conductivity. Equal to the weight based on the conductivity of the aluminum was almost twice times that of copper.
Thermal conductivity rate
Thermal conductivity rate is about copper aluminum alloy becomes prohibitive, which manufactures heat exchangers, evaporators, heating appliances, cooking utensils, as well as automotive cylinder head and radiator are favourable.
Aluminium is magnetic, it is important for the electrical industry and the electronics industry properties. Aluminum is not spontaneous combustion, which involves handling or touching flammable materials are important to the application.
Machining of aluminum is excellent. In various deformation in aluminum and cast aluminum, and after these alloys produce in various States of machining characteristics of considerable, this requires special machine tools or techniques.
