Product Description
Commonly known as copper tungsten contacts, copper rivet tungsten contacts, car horn pure tungsten contacts, nickel-plated tungsten contacts, horn tungsten contacts, snail horn tungsten contacts, high temperature tungsten contacts
The combination of the tungsten contact base and the copper surface is made by a vacuum welding method. The combination of the two has very high strength and does not crack under the action of a high-temperature arc. The base tungsten copper is used as the arc ablation-resistant working surface, which truly realizes the composite of two different materials.
The high melting point tungsten contact of copper tungsten contact has compressive strength and arc ablation resistance. Copper not only improves electrical conductivity, heat conduction and processing performance, but also absorbs a large amount of arc heat when the arc evaporates at high temperature, improving use conditions and reducing electrical corrosion effect.
Copper tungsten contacts have high density, high thermal conductivity, high strength and hardness, low electrical resistivity, low thermal expansion coefficient, and arc burn resistance, welding resistance, galvanic corrosion resistance and other properties in electrical contact materials and electrode materials. The advantage of application is that other materials cannot be replaced in the short term.
It is widely used in the contact points of switches to realize the circuit connection or breaking, the contacts of AC contactors, car horns, electric horns, magneto and other electrical products.
Product size:
1. Copper-tungsten contact size: contact head diameter Φ3*L-Φ8*L;
2. Welded tungsten sheet: powder sintered tungsten sheet, tungsten rod cutting sheet, diameter Φ3~8mm;
3. Welding substrate: Tungsten sheet + copper rivets or iron (stainless steel) rivets, namely copper matrix pure tungsten contacts or iron matrix pure tungsten contacts;
4. Welding method: vacuum high-frequency brazing furnace, so that the tungsten sheets, rivets and solder have been set up The temperature zone of the vacuum welding furnace is controlled to achieve the purpose of tungsten contact welding. 5. Surface treatment: pure tungsten contacts are nickel-plated and not nickel-plated, that is, nickel-plated tungsten contacts on the surface and tungsten contacts without nickel-plated on the surface;
