Composite strips

Overview:
Composite strips are rolled with raw materials of different features (composite strips and basic strips) using advanced composite technique according to different use requirements. They can not only keep and fully play the features of composite components, but also generate useful comprehensive performance thanks to composite effect, in particular, the electrical property and wear-resisting property will be improved significantly compared with the entire pure (gold and silver) contact materials, besides, the products can also save precious metals (gold and silver) and reduce product cost. The main product feature are as follows:
① They grant flexibility to material property design to manufacture contact materials optimizing and combing mechanical property and electrical contact property;
② The precious metals (gold and silver) are only composited at necessary position of electrical contact, thus effectively saving precious metals (gold and silver). The price of contact is low;
③ Composite contact materials are suitable for continuous automatic production of contact parts forming, and no other processing technology is needed after forming (such as welding and riveting), in this way, it will not only simplify the manufacturing process of contact parts, improve production efficiency and reduce cost, but also enhance the assembly precision and reliability of components.

Application: 
Composite materials are mainly used for production of various micro motor brushes and commutators, microswitches, relays, connectors, tuners and other electronic components.
