Electric Copper Contacts Materials : Copper T2Y2,Brass H59/H62/H65
Contacts Surface Treatment: Silver-plated, Gold-plated,Nickel-plated
Features of our Electric Copper Contacts:
1. The raw material of red copper comes from 100% mineral copper, which has good conductivity;
2. The surface is electroplated to prevent oxidation and improve conductivity;
3. Compared with pure silver contacts, greatly reduce the cost of contacts;
4. Non-standard customization can be made according to customer drawing requirements;
5. Simultaneously process various Electrical Silver Contacts, in-die stamping riveting components and welding components to provide customers with solutions;
6. The reputation of the group company is guaranteed and provides technical services to customers.
The Electric Contacts refer to the point of intersection where the electronic appliances are disconnected and contacted when they are opened and closed. Since the metal conductor terminal is prone to instantaneous heat and sparks at the moment of contact, the Silver Contact Point is prone to oxidation and electrolysis in the multi-frequency process of use, so the Electrical Contacts are increased and thickened, or polymer metal is used Manufacturing (copper and silver are the most common materials), so this Electric Rivet Contact made of polymer metal, or a point thickened with the same material is called a Silver Contact.
Copper Rivet materials are generally made of brass or red copper. Copper Rivets use their own deformation or interference to connect the parts to be riveted during riveting. Common Electrical Solid Copper Contacts are round head rivets, flat head rivets, countersunk rivets, and semi-tubular rivets. , Solid rivets, stud rivets, step rivets, etc.
The conductivity and thermal conductivity of silver is the highest among metals. Due to its low hardness, low melting point and low boiling point, silver can only be used for small current contacts such as relays. High current Electrical Silver Contacts are mostly made of silver alloys or composite materials.
Compared with Electric Copper Contacts, Silver Contacts of switch panels or sockets are better. Silver contacts are generally made of silver alloy, which has the advantages of wear resistance, heat resistance, and oxidation resistance. In addition, generally the circuit contacts that have a fire are plated with silver. The inside is copper, and the outside is plated with a very thin layer of silver. The reason is that the silver will form an oxide layer like other metals when the contacts are fired. However, silver oxide is more Pure silver has better electrical conductivity, so if the general contacts cannot avoid ignition, Copper Alloy Contacts or Silver Alloy Contacts are used.
