Copper Tungsten Rivets

Electrical Tungsten Contact Rivets are parts that use their own deformation or interference to connect the riveted parts during riveting. Common ones include semi-circular head rivets, flat head rivets, countersunk head rivets, semi-hollow rivets, solid rivets, mother-and-child rivets, step rivets, etc.

1. There is no flux between the copper tungsten parts and the copper parts, which reduces their own contact resistance;

2. Tungsten and copper are fully combined through infiltration, so that the copper in the Tungsten Electrical Rivets components is not easy to fall off at high temperatures;

3. According to customer needs, copper tungsten, silver tungsten, tungsten carbide copper, tungsten carbide silver and other materials can be used, and there are different ratios of tungsten content of 30%~90% to meet different processing requirements;

4. Good resistance to fusion welding, strong wear resistance, short arc time, strong separability, strong resistance to electrical corrosion and current impact. It can still maintain good arc wear resistance under high current conditions.

The "two-phase metal" Electrical Tungsten Rivets for Contacts use a one-step molding process, with the end material being copper tungsten and the shank being pure copper.

Compared to conventional rivets, Electrical Contact Rivets with Tungsten have many advantages. Since we use direct bonding copper on copper tungsten, it creates very high strength between the bonding areas without any brazing solder at the bonding interface, eliminating the porosity problem of brazing primers. It has a wide range of uses, such as:

1. Round head rivets are mainly used in riveting situations with large lateral loads and are the most widely used;

2. Flat cone head rivets have large heads and excellent corrosion resistance, and are often used in strong corrosion riveting situations such as hulls, boiler water tanks, etc.;

3. Countersunk and semi-countersunk rivets are mainly used in riveting situations with smooth surfaces and small loads;

4. Flat head rivets are used in riveting situations with general loads;

5. Flat head and oval head rivets are mainly used in riveting situations of metal sheets or non-metallic materials such as leather, canvas, and wood;

6. Large flat head rivets are mainly used in riveting situations of non-metallic materials.
