- Primary foundry alloys
Primary foundry alloys are widely used for different parts used in automobile and other engineering industries. Primary foundry alloys are produced in the form of small ingots (6-8 kg), small ingots (15 kg), or a T-shaped ingot.
Cast alloys of primary aluminum are the following systems and standards:
AlSi (including AlSi3, AK7, AK9ch, AK9pch, AK9E, AK9S, AK12, AK12och, AK12pch, EN AB-AlSi9, EN AB-AlSi11, EN AB-AlSi12(a), EN AB-AlSi12(b), alloys with high silicon);
AlSiMg (including AlSi7Mg/A356.2, AlSi10Mg, AlSi11Mg);
AlSiCu (including AK5M2, AK6M2, AK8M, AK10M2N, AK12M2, AK12MMgN).
GOST 11069-2001
GOST 1583-93
International standards and specifications, as agreed with customers.

- Foundry and Basic Pig Iron PL1, PL2
Merchant pig iron comprises three main types: BASIC PIG IRON, used mainly in electric arc steelmaking, HAEMATITE PIG IRON [also known as FOUNDRY PIG IRON], used in mainly in the manufacture of grey iron castings in cupola furnaces, and NODULAR PIG IRON, used in the manufacture of ductile [also known as nodular or spheroidal graphite - SG] iron castings. Pig iron contains at least 92% Fe.
4.0-4.5% carbon,
<1.5% silicon,
<1.5% manganese,
<0.04% sulphur,
<0.3% phosphorus

Die-casting under low and high pressure of aluminum alloys
In castings manufacture are used aluminum alloys AlSi9Cu3 (46000 DIN EN 1706), AlSi12Cu1 (Fe) (47100 DIN EN 1706) and other.
