Clad Aluminum Sheet

The united states mint uses cladding to manufacture coins from different metals.

Clad aluminum sheet.

It offers similar performance to 7075 aluminum but it s not as strong. Corrosion resistance and machinability are rated as fair though the addition of chromium provides good stress corrosion cracking resistance in 7075 aluminum sheet products. 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. Cladding is often achieved by extruding two metals through a die as well as pressing or rolling sheets together under high pressure.

Cladding is the bonding together of dissimilar metals it is different from fusion welding or gluing as a method to fasten the metals together. The pure aluminum is very soft and fabrication processes would severely damage or destroy the clad surfaces. As with alloy 2024 alloy 7075 is available in bare form or in clad alclad to offer even further protection from corrosion. This allows a cheaper metal to be used.

Alclad is a trademark of alcoa but the term is also used generically. Ryerson offers heat treatable aluminum sheet grades like the popular 6061 aluminum alloy that can be used for commercial applications that require strength corrosion resistance and machinability as well as non heat treatable grades when formability and weldability are priorities. While 2024 aluminum was initially designed for structural components in aircraft it s now widely used when a high strength to weight ratio is needed such as for gears shafts and fasteners. Not all aircraft sheet aluminum is clad especially those alloy sheets from which small brackets gussets and fittings are made.

An example of clad aluminum is the surface of unpainted aircraft. Welding is generally not recommended on this aluminum sheet.

These sheets are clad in 1230 aluminum for an added layer of corrosion resistance.
