Copper Electrical Contacts Materials : Copper T2Y2,Brass H59/H62/H65
Contacts Surface Treatment: Silver-plated, Gold-plated,Nickel-plated
Features of our Copper Electrical 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.
Red Copper is the main Contact Point material. The weakness of copper as a contact material is that it is easily oxidized in the air. When the temperature is below 200℃, a CuO surface film can be formed, which can reach 10~1000nm; when it is above 200℃, a CuO surface film is added, and its resistivity can reach 106Ω. When the temperature reaches 120℃, the contact resistance can be increased by 3 times due to the influence of the surface oxide film, and the aforementioned abnormal wear phenomenon will also occur in the oil. Its solubility and arc resistance are not as good as tungsten (W) and molybdenum (Mo). ) And other metals. However, from the perspective of comprehensive indicators such as electrical conductivity, arc resistance, and price, Electric Copper Contacts are the most widely used contact material, and many multi-element composite materials (alloy or powder metallurgy) are also based on copper.
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.
The characteristics of Silver Electrical Contacts are that it increases the frequency of use of conductors, increases the contact effect, and enhances the performance of conductors. Silver Contact Rivets are widely used in the production of electronic appliances, such as switches, relays, and the intersection fulcrums in conductive lines, etc. , It is mainly riveted to the terminals of various accessories by using a silver riveting machine. The main materials used for Electronic Contacts are silver,copper,iron,aluminum, etc, generally need to be silver plated to enhance its conductive effect and prevent oxidation .
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.
