Clad Aluminum Alloy Sheet

7075 aluminum is among the highest strength alloys available and used in highly stressed parts.

Clad aluminum alloy sheet.

This thin layer usually makes up 5 to 10 of the total thickness of the brazing sheet. Brazing sheet comprises of a core alloy clad on 1 or 2 sides with a lower melting aluminum silicon al si alloy. Alloy 7075 aluminum coil and sheet have been and remain the baseline standard with a good balance of properties required for aerospace applications. Aluminum cladding is cladding that is created using a thin coating of aluminum on the exterior of the product.

7075 is the strongest aluminum with the strength of many steels while retaining aluminum s lightweight qualities. Alclad is a trademark of alcoa but the term is also used generically. The cladding on this sheet gives it exceptional corrosion resistance. It has a melting point of about 500 degrees celsius or 932 degrees fahrenheit.

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. The trade name of this aluminum laminate as originated by the aluminum company of america is alcad. Typical uses for 2024t3 alclad aluminum sheet are aircraft skins cowls aircraft structures and also for rv repair and restoration like airstreams because of its shiny finish 2024t3 alclad 208. It melts and flows during the brazing process to provide upon cooling a metallic bond between the components.

Aluminum sheet plate 7075 clad is normally used for aerospace military and automotive applications. Alclad aluminum sheet is a late game component used for building mk 5 conveyor belts and lifts among other things. Thin lightweight highly durable sheet that is mainly used for products that need to be light or have high heat conduction. Welding is generally not recommended on this aluminum sheet.

Light green sheets components of clad aluminum alloy products this publication is the registration record for clad aluminum alloy products registered with the aluminum association and contains the registered designations component alloys cladding location and other information. From this trade name the adjective clad and the verb cladding have been derived. Corrosion resistance and machinability are rated as fair though the addition of chromium provides good stress corrosion cracking resistance in 7075 aluminum sheet products. The trade name of this aluminum laminate as originated by the aluminum company of america is alcad.

Cladding in general is the application of one type of substance or material over a different material effectively creating a protective layer on the underlying material. From this trade name the adjective clad and the verb cladding have been derived.
