Tungsten Fasteners

The Tungsten Fasteners include bolts, screws, nuts, washers, and other fasteners made of pure tungsten or tungsten-based alloys. They are designed for use in extreme environments that require high strength, heat resistance, and chemical stability.

High Strength
Pure tungsten has a tensile strength of 900-1510 MPa, so it will not loosen or break under high load or strong vibration. Tungsten also maintains its strength at high temperatures, with a recrystallization temperature of over 1200 degrees Celsius. This means that even if heated for a long time, the fastener will not deform or produce stress creep, thereby extending the service life of the equipment.

Low Thermal Expansion
Tungsten has a thermal expansion coefficient of only 4.5×10⁻⁶/Kelvin, which is much lower than stainless steel (about 17×10⁻⁶/Kelvin) and titanium alloy (about 8.6×10⁻⁶/Kelvin). Tungsten Fasteners will not deform in environments that require repeated heating and cooling. This avoids thread loosening or assembly misalignment caused by thermal expansion and contraction, so they are very suitable for fastening systems for high-precision structures.

- High melting point, high temperature stability

- High hardness

- High strength

- High corrosion resistance

Tungsten fasteners are widely used, mainly including the following aspects:

- High temperature environment:

They are often used in various high temperature furnaces, vacuum furnaces, sapphire crystal growth furnaces, melting furnaces, sintering furnaces and other high temperature environments due to their high melting point and excellent high temperature resistance. They can withstand extreme high temperatures while maintaining structural strength and integrity.

- X-ray and radiation shielding:

They are used to fix shielding components such as lead plates or tungsten alloy blocks to provide protection against harmful radiation. They are widely used in medical, scientific research and other fields.

- Electrical discharge machining:

They are used to fix electrodes, transmit current, and ensure the stability and precision of the machining process.

- Aerospace and defense:

Tungsten and molybdenum fasteners are used in key components such as engine components, rocket structures and satellite systems to ensure safe and reliable operation.

- Semiconductor wafer processing:

They are used to fix wafer processing components to ensure the stability and precision of the processing process.

Other fields: It is also used in automotive, electronic construction and other fields

The production process of tungsten fasteners usually includes:

Coil forming -- Annealing and pickling -- Wire drawing-- Cold heading -- Thread rolling -- Heat treatment -- Surface treatment. These process steps are crucial to ensure the accuracy and performance of fasteners.
