Provide 3 reason's for using aluminium to make car wheels?
Lightweight - Aluminum is about one-third the weight of an equal volume of copper, steel or brass.Strength - Aluminum can withstand heavy loads and pressure; when alloyed appropriately, its strength approaches that of steel.Corrosion resistance - The formation of a microscopic film of aluminum oxide on the surface of the metal protects it against the corrosive influences of water, salt and other influences.Some other minor reasons includeAvailability - Aluminum is the most abundant metallic element in the earth's crust.Cost-efficiency - Aluminum processing is inexpensive.
