Corrosion resistance and machinability are rated as fair though the addition of chromium provides good stress corrosion cracking resistance in 7075 aluminum sheet products.
Aluminum clad sheet.
An example of clad aluminum is the surface of unpainted aircraft.
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.
As with alloy 2024 alloy 7075 is available in bare form or in clad alclad to offer even further protection from corrosion.
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.
Minimum sheet size available is 2 x 4.
Order by part number.
Not all aircraft sheet aluminum is clad especially those alloy sheets from which small brackets gussets and fittings are made.
Aluminum clad panels are an excellent replacement for aluminum mdo plywood and thick gauge plastics.
It has a melting point of about 500 degrees celsius or 932 degrees fahrenheit.
The pure aluminum is very soft and fabrication processes would severely damage or destroy the clad surfaces.
This unique composition makes it approximately one half the weight of aluminum.
