Description

Aluminium A99 applies: for the production of billets cast by semi-continuous method or continuous casting, and is intended for rolling into sheets, strip for anodes of oxide-semiconductor capacitors and other semi-finished products; metered-dose granules of aluminium for the manufacture of elements of the circuits (the conductive plates of a film capacitor) by vacuum-thermal deposition; the foil used to manufacture capacitors; ingots, wire; wire for wire and cables and also wire for welding (Sva99) and for other purposes; aluminium powder Kommandos brands of APS-1, APS-1B, APS-2, APS-3 is intended for the production teploperenosa deformable material type SAP.

Note

High purity aluminium.
Aluminum grade A99 corresponds to the chemical composition of the marches of aluminium EN AW-1199 established in the European standard EN 573−3-94 and Marche 1199, registered by the American aluminum Association.
