ALUMINIUM INGOTS OF VARIOUS GRADES FROM ALUMINIUM SCRAPS

Ingots are very large casting products, greater in size and shape than blooms, billets and slabs. Ingot generally has rectangular/square cross section, but it is not necessary that it should be uniform through out its length. (Ingot may have variable cross section.)

Aluminium Alloy Ingots Iike LM-2, LM-4, LM-6 which are commonly used in Gravity and Sand Casting, Pressure Die Casting Alloys like LM-13, LM-14, LM-24, ADC-12, ALSI-132 etc are also being manufactured as per the Indian and International standards.

Classification of aluminum alloys

Classification of aluminum alloys is established by the International Alloy Designation System (IADS), based on the classification developed by Aluminum Association of the United States.

This classification is accepted by most countries.

    wrought aluminum alloys
    cast aluminum alloys

Wrought aluminum alloys

Wrought aluminum alloys are used in the shaping processes: rolling, forging, extrusion, pressing, stamping.

There are two principal groups of the wrought aluminum alloys:

    Non-heat-treatable alloys
    Heat-treatable alloys
    Phase composition of wrought aluminum alloys

Non-heat-treatable alloys

Non-heat-treatable alloys cannot be strengthened by heat treatment.

Alloys of 1xxx, 3xxx, 4xxx and 5xxx series are non-heat-treatable.

The initial strength of these alloys is achieved due to the hardening effect of the alloying elements: manganese (Mn), silicon (Si), magnesium (Mg).

Additional hardening of these alloys is done by cold work (strain hardening).

Non-heat-treatable alloys are ductile and moderately strong (depending on the alloying elements concentration).

The alloys from this group are supplied either in O condition (annealed) or in H condition (cold worked at various degrees).

Non-heat-treatable alloys are used for manufacturing deep drawn parts, sheets, foil, tubes, wire, extruded parts, pressure vessels.
