Clad Aluminum Sheet
Corrosion resistance and machinability are rated as fair though the addition of chromium provides good stress corrosion cracking resistance in 7075 aluminum sheet products.
Clad aluminum sheet. Not all aircraft sheet aluminum is clad especially those alloy sheets from which small brackets gussets and fittings are made. 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. 3 ton roll of copper clad aluminum sheet for electric power cold rolling process 0 05 0 1mm ultra thin h65 h90 t2 aluminium clad sheet 5 series 6 series for cable lightweight copper clad aluminum sheet with high electrical conductivity. An example of clad aluminum is the surface of unpainted aircraft.
The pure aluminum is very soft and fabrication processes would severely damage or destroy the clad surfaces. Architectural metal roofing panels metal wall panels and related products such as soffit panels highest quality fascia and coping systems. The united states mint uses cladding to manufacture coins from different metals. It offers similar performance to 7075 aluminum but it s not as strong.
Cladding is the bonding together of dissimilar metals it is different from fusion welding or gluing as a method to fasten the metals together. Steel aluminum stainless copper brass mdf particle board plywood acrylic plastic foam for over 50 years clad rex has been laminating vinyl to metal sheet and with the additional of a new state of the art coating system we are now able to apply any decorative film or high pressure laminate to any flat substrate. Cladding is often achieved by extruding two metals through a die as well as pressing or rolling sheets together under high pressure. 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. Welding is generally not recommended on this aluminum sheet. As with alloy 2024 alloy 7075 is available in bare form or in clad alclad to offer even further protection from corrosion. It has a melting point of about 500 degrees celsius or 932 degrees fahrenheit.
Alclad is a trademark of alcoa but the term is also used generically.
