Analysis of raw materials of silver-tungsten alloy contacts

    Silver-tungsten grades are mainly used in metal electrodes and their arc welding raw materials; such as low-voltage automatic switches, vacuum circuit breakers and overload protectors. It is widely used in high temperature resistant coatings, electrical alloys for high voltage circuit breakers, metal processing electrical grades, and raw materials for microelectronics technology. Sports equipment and other fields.

    Titanium carbide TiC porcelain has a face-centered cubic crystal structure, high-quality copper-silver alloy contacts with high melting point, good thermal conductivity, high strength, stable organic chemistry, no hydrolysis reaction, good continuous high temperature oxidation resistance, no acid at room temperature. It reacts, but it can be dissolved in the mixed acid of sodium cyanide and hydrochloric acid to generate nitrogen compounds in a hydrogen atmosphere at 1000 °C. After the machinery manufacturing industry is converted back to high-quality technical engineering drawings, it cannot obtain overseas orders and purchases due to the unqualified production process of lead-brass extrusion casting. Because the price is too high, some choose to substitute alloy copper for production, resulting in a long service life. short, leading to great confusion.

    When the machinery and equipment purchased by various mining companies, high-quality copper alloy contact couplings or tiles have reached their service life, because overseas manufacturers do not even provide engineering drawings for consumable parts, let alone tell them. Materials and processing methods, even if you understand the materials, you can't produce them. Only the manufacturer can buy it, the price is very high, but it is impossible, and it can only be bought at a sky-high price.

    The application of silver-tungsten alloy is similar to that of tungsten-copper alloy. Tungsten-silver aluminum alloy was once used as the nozzle throat lining of solid rockets. In electrical switches, tungsten-silver-aluminum alloys are widely used in low-voltage isolating switches, automatic switches, AC contactors, etc., which require good oxidation resistance, higher electrical and thermal conductivity, and smaller specifications of high-quality silver-cadmium alloy contacts. Open and close places where actual operations are frequent.
