99.95% pure Tungsten twisted wire twisted filament
Tungsten wire is a high-performance metal wire, usually made of tungsten alloy. Its product structure is mainly composed of fine wires made of tungsten alloy and special ceramic materials, used to improve its high temperature resistance and oxidation resistance. The production process of tungsten wire includes using single or multiple strands of tungsten wire to wrap and produce. During the production process, the tungsten wire will undergo a secondary inspection to ensure that the wire diameter is uniform, without internal cracks, splits, continuous pits, scratches, and other issues, in order to meet high-quality requirements.

Lighting industry
Tungsten wire has important applications in the lighting industry, especially in conventional lamps such as incandescent lamps, halogen lamps, and fluorescent lighting. It serves as a filament or electrode, providing a stable light source for the luminaire.
Vacuum coating industry
In the vacuum coating industry, tungsten wire is widely used for surface coating of cathode ray tubes, mirrors, and various plastics, organic compounds, and metal substrates. It serves as a heating element to provide necessary thermal energy for the vacuum coating process.
Electronics industry
In the electronics industry, tungsten wire is often used as a heating element or electrode due to its high temperature resistance and good stability, which can ensure the normal operation of equipment.
Ceramic and heat treatment industry
Tungsten twisted wire is also widely used in the ceramic and heat treatment industries. Due to its high melting point and excellent high-temperature performance, it is often used as a heating element in equipment such as high-temperature furnaces and sintering furnaces, as well as a supporting and reinforcing structure during heat treatment processes.
Tungsten filament is coiled for a variety of reasons, particularly in applications such as incandescent light bulbs and other heating elements:
1. Increase Surface Area: Rolling up the wire increases its surface area, which allows for more efficient heat distribution. This is important for applications such as light bulbs, where the wire needs to emit light efficiently.
2. Compact Design: Coiling allows for a more compact design, allowing the wire to fit into smaller spaces while still providing the length needed to heat or emit light. This is critical for devices where space is limited.
3. Enhanced Heating Efficiency: The coiled shape helps concentrate the heat generated by the filament, allowing it to reach higher temperatures faster and more efficiently. This is especially important for incandescent lamps, as the filament needs to reach high temperatures to produce visible light.
4. Mechanical stability: Coiling provides mechanical stability to the wire, reducing the risk of breakage during operation. The coiled structure helps to more evenly distribute stress across the filament.
5. Light output control: In lighting applications, coil design can provide better control of light output and color temperature because the geometry of the coil can affect how the light is emitted.
Overall, coiled tungsten wire is a practical design choice that can improve performance, efficiency, and durability in a variety of applications.
Stranded wire is generally considered stronger than straight wire for the following reasons:
1. Enhanced Structural Integrity: Twisting the wires together creates a composite structure that distributes stress more evenly across the length of the wire. This helps prevent localized weaknesses that can occur in individual strands of wire.
2. Enhanced resistance to bending and pulling: The twisting process can improve the wire's resistance to bending and pulling forces. Twisted wire can absorb and disperse these forces better than straight wire, thereby reducing the possibility of breakage.
3. Increased Flexibility: Stranded wire is more flexible than straight wire and can be bent without breaking. This flexibility is very useful in applications where the wires need to be frequently manipulated or moved.
4. Reduce Fatigue: Twisting helps reduce the effects of metal fatigue. When the wire is twisted, stress is more evenly distributed, which can extend the life of the wire under cyclic loading conditions.
5. Increased bonding surface area: In applications where wires are joined or bonded (such as electrical connections), stranded wire can provide a larger contact surface area, thereby improving the strength of the connection.
6. Better resistance to environmental factors: Depending on the materials and stranding techniques used, stranded wire can also provide better resistance to environmental factors such as corrosion and abrasion.
Overall, the twisting of the wire enhances its mechanical properties, making it stronger, more durable and suitable for a variety of applications.
