There is a foundry in our plant. The foundry manufactures wrought aluminium alloys (GOST 4784-97, GOST 9498-81, GOST 23855-79, OST 1 90048-90, OST 1 92014-90), as well secondary casting alloys (GOST 295-79, GOST 1583-93, OST 1 90377-87), standard ingot up to 16 kg, large ingot of 580-600 kg. Melting units of up to 35 tons capacity, semicontinuous casting machines, including electromagnetic casting, special aluminium alloys refining systems for removal of gases, oxide inclusions, impurities, modified structures, equipment for heat treatment and mechanical treatment provide production of billets for manufacture or products to be used in aircraft and space machinery, as well in motor industry, shipbuilding, construct complex and other industry branches.
More then 60 qualities of alloys are manufactured, including ÀÊ4, ÀÊ4-1, ÀÊ6, ÀÊ8, Ä1, Ä19, Ä20,ÀÄ0, ÀÄ1, ÀÌÖ, ÀÌÃ2, ÀÌÃ3, ÀÌÃ6, 1561, Â95, Â95Ï×, ÀÂ87, ÀÊ5Ì", ÀÊ12Ì2, ÂÀË10 and others. Wrought aluminium alloy products being manufactured:
· Flat ingots (slabs) of 400 x 1700 mm section
· Solid round ingots of 100 to 505 mm in diameter and up to 6000 mm by length
· Hollow round ingots (156 to 505 mm by external diameter, 43 to 340 mm by internal diameter, up to 6000 mm by length).
By customer's request, ingots of other diameters and also blending bars of cast and wrought aluminium alloys from 14 kg to 1000 kg by mass can be manufactured. Depending on purposes, billets with regulated gas content, high efficiency of removing non-metallic inclusions, with heat and mechanical treatment can be manufactured.
