Clad Aluminium Sheet

Minimum sheet size available is 2 x 4.

Clad aluminium sheet.

Not all aircraft sheet aluminum is clad especially those alloy sheets from which small brackets gussets and fittings are made. Pure aluminum has considerable corrosion resistance compared to aluminum alloys. 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. But it has little or no structural strength. As with alloy 2024 alloy 7075 is available in bare form or in clad alclad to offer even further protection from corrosion. 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.

Corrosion resistance and machinability are rated as fair though the addition of chromium provides good stress corrosion cracking resistance in 7075 aluminum sheet products. 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. Alclad is a trademark of alcoa but the term is also used generically.
