Edelmantelmetall

Precious Clad Metal is a kind of new functional composite material. It is based on the copper or copper alloy. Precious metal, silver or silver alloy are cladded on the base metal as an inlay or overlay through special bonding process. Precious Clad Metal is a new technical material, based on different industry needs, formed by advanced indoor temperature composite technology or Hot Composite Technique; It is rolled with different characteristic material strips composite alloy material and base material strip. Their alloy and base material characteristic are well preserved, and their compound characteristic are very good, esp. its electrical character and its wearability are much better than single precious metal contact material (such as gold and silver). Beside, it is a saving of precious metal, keeping low cost and consistency of social development. Its characteristics as follows: offer flexibility of material design; being able to produce the electrical contact with high mechanical and electrical contact characteristics save precious metal materials with low prices, as precious metal is only used at electrical contact spots. Precious Clad Metal Material is suitable for continuous automatically manufacture. It does not need other manufacture process, such as welding or soldering after its formation. It simplifies manufacturing process of electrical parts with high productivity and low cost and raises the assembly precision credibility of electrical component. Precious Clad Metal is used for all sorts of electrical component production, such as, micro motors, electrical brush, commutator, jiggle plug/socket, relay, connector, tuner, etc. Precious Clad Metal production line has Germany Hi-precision Roller Machine; Hi-precision Vertical Cutting Machine; Slotting Machine; Ionic Absorption Test System AAS; Light Processor & Metallographic Microscope; Digital Light Processor; Strength Tester; Hardness Tester and other 220 production and testing equipments. As clients requirement, we can make different foils, annual output 300 tons. Precious Clad Metal Size and Tolerance cladding material thickness: 0.03-3.0 mm; width: 5-120 mm.
