Clad Aluminum Sheet

It offers similar performance to 7075 aluminum but it s not as strong.

Clad aluminum sheet.

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. 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. Corrosion resistance and machinability are rated as fair though the addition of chromium provides good stress corrosion cracking resistance in 7075 aluminum sheet products. 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. Welding is generally not recommended on this aluminum sheet. Not all aircraft sheet aluminum is clad especially those alloy sheets from which small brackets gussets and fittings are made. 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 united states mint uses cladding to manufacture coins from different metals. Architectural metal roofing panels metal wall panels and related products such as soffit panels highest quality fascia and coping systems. 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. An example of clad aluminum is the surface of unpainted aircraft.

It has a melting point of about 500 degrees celsius or 932 degrees fahrenheit. Cladding is often achieved by extruding two metals through a die as well as pressing or rolling sheets together under high pressure. The pure aluminum is very soft and fabrication processes would severely damage or destroy the clad surfaces. These sheets are clad in 1230 aluminum for an added layer of corrosion resistance.

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.
