- Light Weight: The specific gravity of aluminum is 2.7 about one-third that of iron. B. Easy to work: Aluminum can be easily fabricated into various forms.
- Easy to Recycle: Due to low melting temperature, it saves energy and protects nature.
- Excellent corrosion resistance: When aluminum is exposed to air, a third oxidized film forms on the surface protecting the metal from corrosion.
- Strong & sound shock-absorbing: Depending upon the alloy or temper of aluminum, strength of up to 600kg/mm2 can be reached because of low modulus of elasticity, it is used for automobile bumpers.
