Aluminum

• Aluminum is a light metal & easily machinable; has wide variety of surface finishes; good electrical and thermal conductivities; highly reflective to heat and light.

• Versatile metal - can be cast, rolled, stamped, drawn, spun, roll-formed, hammered, extruded and forged into many shapes.

• Aluminum can be riveted, welded, brazed, or resin bonded.

• Corrosion resistant - no protective coating needed, however it is often anodized to improve surface finish, appearance.

• Al and its alloys - high strength-to-weight ratio (high specific strength) owing to low density.

• Such materials are widely used in aerospace and automotive applications where weight savings are needed for better fuel efficiency and performance.

•     Al-Li alloys are lightest among all Al alloys and find wide applications in the aerospace industry.
