Electrical contact materials have a history of nearly 100 years, initially using pure silver, pure gold, pure platinum to make contact materials; the 1940s began to use Ag, Cu, Au_Ag, Pt_Ir, Pd_Ag and other pure metals or alloys; since the 1960s the development of multi-precious metals and a variety of precious metal composite electrical contacts characteristics

Solid rivets are generally made of aluminum, copper, iron, etc., and the surface treatment is white zinc plating. The use of rivets for the implementation of the connection - a rigid connection, is not removable. Small rivets can be cold riveted, while large rivets are hot riveted in the red hot state.

Tungsten copper rivets are parts that use their own deformation or interference to connect the riveted parts in riveting. Commonly used are semi-round head rivets, flat head rivets, countersunk head rivets, semi-hollow rivets, solid rivets, rivets, step rivets, etc.

Sterling silver contacts, contacts, rivets Ag sterling silver and fine-grained silver have high electrical and thermal conductivity, low and stable contact resistance, good welding and processing performance, and crystalline silver is added in a small amount of silver.

Use machines to process animal and aquatic food. Crushing knives, breaking hammers, particle knives, filters, fuel drying nets, vacuum cleaners, air conditioners, generator cooling, mechanical protection nets, machinery manufacturing accessories, meshes for machining machines, mechanical equipment, working floors (non-slip) , Mesh protection for supermarket shelves.

Rivet contact products are manufactured by cold heading forming method. The main

Electrical stamping parts refer to the hardware used for electrical appliances,

Metal Copper Stamping Component are made of copper metal materials and processed

The conductivity of copper only second to  silver and superior to all other metals, so it  was  used as benchmarks  for the conductive properties of the material.Not only copper  has excellent electrical conductivity, but also  high melting point (1083 ℃), good mechanical properties,

Silver and fine grain silver(FAg)possess very high electrical and thermal conductivity,low and stable contact resistance,and good workability.For silver resistance to arc erosion and contact welding are limited,mechanica strengthis low, Due To the small quantity of nickel in the fine grain silver,

AgNi materials have higher resistance to arc erosion and contact welding than Ag or FAg.Both Properties are improved withincreasing Ni content. All AgNi materials show good workability and are easy to weld to contact supports.

AgCdO contacts belong to the group of the most widely used ones on the field of low voltage electric apparatus.They combine a satisfactory resistance against contact welding with a good arc erosion resistance and a fairly low contact resistance over its complete service life.

By introducing certain additives,the AgSnO2 materials,produced by the powder metallurgy technique can be modified in such a manner that contact resistance and over temperature behavior can be maintained low and stable over service life.
