Tinten wire is used primarily to create filaments of fluorescent and incandescent lamps as well as halogen lamps.
Description of High Purity Tungsten Wires for High Temperature Heating Wire:
High melting point: The melting point of high-purity tungsten wire is as high as 3410℃, which has good high-temperature resistance. In a high-temperature environment, the strength and hardness of tungsten wire can still maintain a high level, so it is widely used in high-temperature furnaces, high-temperature test equipment, high-temperature processing tools, and other fields.
High strength: purity tungsten wire has a high tensile strength, up to 500-1000MPa at room temperature and up to 2000MPa at high temperature. Therefore, high-purity tungsten wire can manufacture high-strength and high-hardness parts and components, such as turbine blades and rocket nozzles, in the aerospace field.
High resistivity: High purity tungsten wire resistivity, about 5.3μΩ·cm, can maintain a stable resistance value at high temperatures. Therefore, high-purity tungsten wire is widely used to manufacture high-temperature resistance, heating elements, and high-temperature electronic devices.
Good corrosion resistance: purity tungsten wire is not easy to oxidize or corrode at high temperatures and has good corrosion resistance. In a reducing atmosphere, the surface of the tungsten wire will form a dense tungsten oxide film, which can protect the tungsten wire from further oxidation.
Good processing performance: high purity tungsten wire has good processing performance and can be cut, grinding, drilling, and other processing operations. During the processing process, the sharpness and accuracy of the processing tools should be maintained to avoid excessive stress or deformation.
Good fatigue resistance: High-purity tungsten wire has good fatigue resistance, can be stable under periodic changes in stress, and is suitable for manufacturing parts and components that need to withstand repeated pressure.
Production Method of High Purity Tungsten Wires for High Temperature Heating Wire:
Raw material preparation: Select high-purity tungsten powder as raw material. Its purity should be higher than 99.9%. Particle shape and particle size distribution of tungsten powder will affect the final product's performance.
Molding: Tungsten powder is made into a particular shape and can be used to press molding, extrusion molding, injection molding, and other methods. Factors such as pressure, temperature, and time should be controlled during the molding process to ensure the density and strength of the green.
Sintering: The green billet is sintered at high temperatures to densify and strengthen it. The sintering temperature and time should be determined according to the desired tungsten wire performance to ensure the tungsten wire's high melting point, strength, and resistivity.
Processing: Processing, including cutting, grinding, drilling, etc., can be selected according to the need for different processing methods. During the processing process, the sharpness and accuracy of the processing tools should be maintained to avoid excessive stress or deformation.
Heat treatment: To further improve tungsten wire's mechanical and electrical properties, heat treatment is required. Heat treatment, including quenching, tempering, and other steps, can improve the grain structure of tungsten and enhance its hardness and wear resistance.
Quality inspection: tungsten wire quality inspection, including appearance inspection, size inspection, performance testing, etc., to ensure it meets the quality requirements.
Application of High Purity Tungsten Wires for High Temperature Heating Wire:
Electronic field: High-purity tungsten wire is widely used in the electronic area, such as manufacturing high-temperature resistance, high-temperature heating elements, and high-temperature electronic devices. Because high-purity tungsten wire has high resistivity and good high-temperature stability, it is one of the ideal materials for manufacturing these electronic components. In addition, high-purity tungsten wire can also be used to manufacture a variety of electronic device brackets, lead frames, electrical contacts, and so on.
Aerospace: High-purity tungsten wire plays an essential role in the aerospace field and can manufacture high-strength, high-heat-resistant parts such as turbine blades of aircraft engines and rocket nozzles. Because high-purity tungsten wire has a high melting point and high strength, it can maintain stable performance in high-temperature environments, so it is one of the ideal materials for manufacturing these parts.
Military field: High-purity tungsten wire is also widely used in the military, such as manufacturing armor-piercing shells, tank engine nozzles, etc. Because high-purity tungsten wire has high strength and hardness and can remain stable under high-speed impact, it is one of the ideal materials for manufacturing this military equipment.
Nuclear industry: High-purity tungsten wire plays an essential role in the nuclear industry, such as manufacturing atomic reactor components, radioactive material containers, etc. Because high-purity tungsten wire has high corrosion resistance and low radioactivity, it can effectively prevent the leakage of radioactive substances, so it is one of the ideal materials for manufacturing nuclear industry equipment.
