The company Evek GmbH offers to buy cobalt at affordable prices. The price is from the manufacturer. The supplier guarantees product delivery to any destination.

Production

Cobalt is produced as ingots, sheets, plates or strips of any size cut from cathode sheets. Maximal size of the slabs is 550x550 mm, minimal size is 20x20 mm. The weight of the ingots shall not exceed 25 kg.
Edges of cathode cobalt plates should be trimmed from four sides. It is allowed to manufacture cathode cobalt sheets with uncut edges as agreed with the customer.

Quality

Cathode cathode plates, ingots, plates and strips of cobalt must be free of salt deposits, pollution and foreign inclusions. The surface of cathode plates, ingots, plates and strips must have discoloration, depressions and dense humping. The area of depressions and dense humping should not exceed 10% of the area of the sheet, plate, ingot or strip. Holes from sampling are allowed in sheets, plates, strips and bars.
