Copper tungsten rivet function and use
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.
Advantages of copper tungsten rivets
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 by infiltration, so that the copper in the tungsten-copper rivet element is not easy to fall off at high temperature.
3. According to the needs of customers, copper tungsten, silver tungsten, tungsten carbide copper, tungsten carbide silver and other materials can be used, and there are different proportions of tungsten content of 30%~90% to meet different processing requirements.
4.Good welding resistance, strong wear resistance, short arc time, strong separability, resistance to electric corrosion, and strong current impact performance. It can still maintain good arc wear resistance under high current conditions.
Copper tungsten rivet use
"Two-phase metal" copper-tungsten rivets use a one-step forming process, the tip material is copper-tungsten, and the shank is made of pure copper. Compared with traditional rivets, tungsten-copper rivets have many advantages. Since we use direct bonding on copper-tungsten Copper, it develops very high strength between bonding areas without any brazing solder at the bonding interface, thus eliminating the porosity problem of the braze primer. It is very versatile
1.Round head rivets are mainly used for riveting occasions with large lateral loads, and are the most widely used.
2.Flat cone head rivets are often used in strong corrosion riveting occasions such as ship hulls and boiler water tanks due to their large head and excellent corrosion resistance.
3.Countersunk head and semi-countersunk head rivets are mainly used for riveting occasions with smooth surface and small load.
4.Flat head rivets are used for riveting occasions with general load;
5.Flat head and flat head rivets are mainly used for riveting of metal sheets or non-metallic materials such as leather, canvas, and wood.
6.Large flat head rivets are mainly used for riveting of non-metallic materials.
