Clad Sheet Aluminum Alloy

An aluminum alloy is a chemical composition where other elements are added to pure aluminum in order to enhance its properties primarily to increase its strength.

Clad sheet aluminum alloy.

This allows a cheaper metal to be used. The thickness of the cladding on each surface may according. The united states mint uses cladding to manufacture coins from different metals. It has a melting point of about 500 degrees celsius or 932 degrees fahrenheit.

The fuselages of civil aircraft are for the most part made from 2024 alloy sheet clad on either surface with a low composition aluminum alloy a 1050 or 1070 alloy for example. As an alternative one side can be clad with a non braze alloy e g. Cladding is the bonding together of dissimilar metals it is different from fusion welding or gluing as a method to fasten the metals together. Alclad is a corrosion resistant aluminium sheet formed from high purity aluminium surface layers metallurgically bonded rolled onto to high strength aluminium alloy core material.

Depending on the desired final properties the core is either homogenized or not before the cladding. The trade name of this aluminum laminate as originated by the aluminum company of america is alcad. From this trade name the adjective clad and the verb cladding have been derived. Anodized 5005 sheet for architectural applications and 5182.

Cladding is often achieved by extruding two metals through a die as well as pressing or rolling sheets together under high pressure. An extremely thin sheet of pure aluminum laminated onto each side of an aluminum alloy sheet improves the corrosion resistance with little impairment of strength.
