Electrical Copper Contacts Materials : Copper T2Y2,Brass H59/H62/H65
Contacts Surface Treatment: Silver-plated, Gold-plated,Nickel-plated
Features of our Electrical 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.
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.
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.
Copper, also known as red copper, has good electrical conductivity and thermal conductivity, excellent plasticity, easy to heat and cold press processing, and is widely used in the manufacture of Copper Electrical Contacts, wires, cables, electric brushes, and electric sparks. Products requiring good electrical conductivity, such as copper. The electrical and thermal conductivity of copper is second only to silver, and it is widely used to make electrical and thermal equipment. Red copper has good corrosion resistance in the atmosphere, sea water, some non-oxidizing acids, alkalis, salt solutions and a variety of organic acids, and is used in the chemical industry. In addition, red copper has good weldability and can be processed into various semi-finished and finished products through cold and thermoplastic processing.
