Which is better,aluminium or aluminum ?
The use of aluminum as a conductor. Aluminum conductive properties of good strength enough, the price is much lower than copper, so in the power transmission system has been widely used. As a structure, the majority of an aluminum alloy. Strength aluminum alloy than pure aluminum through high corrosion resistance higher than that of pure aluminum.
Low hardness aluminum untreated, but after hard anodized treatment, the surface can get very high hardness thick oxide film, an aluminum layer hardness also varies depending on the material composition, the highest hardness of up to HV650, aluminum film maximum hardness, salt spray test after thousands of hours of non-corrosive.
Aluminum insufficient hardness, cutting performance is poor. There are a variety of aluminum alloy, its hardness is represented by HB.
Aluminium and aluminum alloys are metal and they use different as aluminum can be used in food packaging and industrial manufacturing. Aluminum toughness is good, that is, it can be stretched collapsed. Aluminum has a certain hardness, corrosion resistance, so It can be used as windows and doors.
