Alloy 3105 Aluminum Plate Sheet 

    Aluminum alloy 3105 plate sheet is essentially a 98% aluminum alloy with minor additions to increase strength over that of alloy 1100 and 3003, It is not hardenable by heat treatment and it has good corrosion resistance, formability and wedability.

3105 Aluminum Plate

    Typical applications include general sheet metal work requiring greater strength than is provided by 1000 series aluminum alloys, residential siding, mobile homes and sign making.


  Commonly used in the manufacture of residential siding, mobile homes, and rain carrying goods. commonly used in sheet metal work. Commonly used for coating with lacquer for curtain wall, outside of construction.

Fabrication and Heat Treatment

3105 Aluminum sheet


Aluminium / Aluminum 3105 alloy plate sheet has average machinability. However, its machinability can be increased in harder tempers than in annealed condition. Oil lubricants are used for machining this alloy.


Aluminium / Aluminum 3105 alloy plate sheet has good forming characteristics. It is suggested that bend radii should be used in one thickness to 2 t range for annealed H12, H14 and H16 tempers. Bend radii of 2 to 7 t should be used for the H18 temper.


Aluminium / Aluminum 3105 alloy plate sheet has good weldability. It can be welded using arc welding method.

Heat Treatment

Aluminium / Aluminum 3105 alloy plate sheet does not react to heat treatment except during cold working.


Aluminium / Aluminum 3105 alloy plate sheet can be forged at the temperatures ranging from 372 to 510째C (700 to 950째F).

Hot working

Aluminium / Aluminum 3105 alloy plate sheet can be hot worked at 205 to 372째C (400 to 700째F)

Cold Working

Aluminium / Aluminum 3105 alloy plate sheet  has good cold working characteristics in the harder cold worked tempers.


Aluminium / Aluminum 3105 alloy plate sheet is annealed at 344째C (650째F) followed by cooling in air.


Aluminium / Aluminum 3105 alloy plate sheet can be hardened only by cold working in H12, 14, 16, 18 or 25 tempers.
