In those cases when it is necessary to achieve high strength and density the billets from bar sections and rolled metal products are widely used. During the rolling of hot cast ingots they undergo repeated compression between rollers rolling mills, which gives high initial preform a strength and uniformity even with a small thickness.
Copper billets, known as rolling preforms are produced with different diameters ranging from 130 to 350 mm and are independent type of products. Copper billets are used as transfer bars in the production of copper sheets, boards, strips, tubes, rods, tires, wire, strip, copper anodes, profiles, bars and circles. Billets with a diameter of over 350 mm can be produced and delivered according to an individual project after agreement with a customer.
