    Description

    Aluminium A7 applies: for the production of pigs, ingots, wire rod, flat ingots, cast by semi-continuous method or continuous casting, and is intended for rolling into sheets, strips and other semi-finished products; extruded pipes with controlled inner diameter from 14 to 42 mm for heat exchangers; heat exchangers evaporators and condensers with two-sided bulge of the channel used in domestic refrigerators and freezers; roll foil used for thermal, hydro and sound insulation; aluminum Kommandos powder brands APS-1A and APS-1B, APS-2, APS-3, designed for the manufacture of teploperenosa deformable material type SAP.

    Note

    Aluminium technical purity.
    Aluminum grade A7 corresponds to the chemical composition of the marches of aluminium EN AW-1070А established in the European standard EN 573−3-94 and grades 1070 and 1170А, registered by the American aluminum Association.
