They are made in wire, strip and profile form by known processing technologies such as extrusion and subsequent annealing and drawing or roll-forming. They are supplied following the manufacturer's internal standards usually related to DIN EN specifications for copper based materials. The most important materials are two – or multiple material layered semi-finished materials with t...
