The main activity of “Stam Trading” AD, in which it has specialized is the produce of aluminium alloys with one of the highest quality criteria on the market. Except the main types of alloys DIN 226, DIN 230, DIN 231 and DIN 239, the firm produces alloys according to specific customer demands as well. Each new and out-of-standard order is considered as a challenge by the firm. In order for the clients’ requirements to be kept, at least three checks of the alloys’ chemical composition are made in the process of their production through two apparatuses for spectral analysis. There is a possibility for correction of elements like Ca , Mn , Sn , Ti. All the alloys are treated in order for the non-metal inclusions to be removed. The technology used by us allows the production of a full scale by-product aluminium alloys.
