Tungsten Alloy Cap Nut
OVERVIEW
Tungsten Alloy Cap Nut is a nut made of an alloy with tungsten as the main component and other metals (such as nickel, iron, copper, etc.) added. It plays an irreplaceable role in high-end fields such as aerospace, national defense, energy, machinery, and medical treatment. With the continuous advancement of processing technology and the gradual reduction of costs, its application scope will be expanded to provide reliable solutions for connection needs under more complex working conditions.
FANMETAL is a professional non-ferrous metal supplier with more than 20 years of production experience, relying on advanced equipment andan expert technical team. It can also provide customers with cost-effective products such as Tungsten Alloy Rod Bar, Tungsten Cube Weights, Tungsten Alloy Balance Fastener, etc.
FEATURES
Mechanical performance advantages
High density, providing greater mass and inertia in a limited space. Excellent tensile strength and hardness, able to withstand high loads and complex stress environments.
High strength and good fatigue resistance
The high fatigue resistance limit enables it to withstand repeated alternating loads without fatigue fracture. Its hardness and wear resistance give it a clear advantage in environments with frequent friction, thus extending its service life.
Good high temperature and chemical properties
Tungsten alloy can maintain good structural stability in high temperature environments, and has good corrosion resistance to most acids, alkalis, and salt solutions, and performs well in humid, corrosive gas or marine environments.
Dimensionally stable and easy to process
The thermal expansion coefficient is low and can still maintain precise dimensional accuracy in an environment with large temperature changes. It can be processed into nuts of various specifications and shapes according to different application requirements to meet the assembly requirements of complex structures.

APPLICATION
- Aerospace: High-strength connectors are used in key parts such as engine combustion chambers, fuselages, wings, and tails, which withstand aerodynamic loads, vibrations, and alternating stresses during flight to ensure structural stability.
- Energy mining industry: Connectors used for deep-sea drilling platforms and submarine pipelines, which can resist seawater corrosion, high-pressure environments, and high torque loads during drilling, reducing the risk of accidents caused by corrosion or fatigue.
- Precision instrument counterweight and stability: Satellite attitude control devices and counterweight connectors for space probes use the high-density characteristics of tungsten alloys to optimize mass distribution and ensure the attitude accuracy and dynamic stability of equipment in space.
- Mining and engineering machinery: High-strength connectors used in engines and transmission systems of excavators, crushers, and mining trucks, which can withstand severe vibrations, impacts, and wear during ore mining, and improve the working efficiency and stability of mining equipment.
- Semiconductor manufacturing equipment: Vacuum chambers and precision bracket connectors that can be used for equipment such as etching machines and ion implanters in chip manufacturing, which can meet the requirements of high vacuum and temperature stability.
- Ships and offshore platforms: can be used to connect and fix the engines and propulsion systems of offshore engineering ships, resist seawater corrosion and the marine atmospheric environment, and maintain connection reliability under ship vibration conditions.
- High-end machine tools and precision machinery: The connecting nuts of precision parts such as spindles and guide rails of CNC machine tools use the dimensional stability of tungsten alloy (low thermal expansion coefficient) to avoid the influence of temperature fluctuations on processing accuracy, and are suitable for high-precision processing equipment for aerospace parts.
- Medical field: The connecting nuts or counterweights of the radioactive shielding device of the nuclear medicine department resist the radiation of radioactive particles while meeting the center of gravity balance requirements of the equipment to ensure the safety of medical staff.
WORKING PRINCIPLE
Tungsten Alloy Cap Nut achieves reliable connection and fastening functions in a variety of harsh environments through its unique physical and chemical properties and reasonable structural design. There are threaded holes inside to achieve connection with the screw. When tightened, the friction between the threads tightly combines the nut and the screw to form a stable connection.
PROCESS
① Tungsten powder purity ≥ 99.9%, mixed with nickel, iron, copper, cobalt and other bonding phase metals.
② High-temperature sintering and densification after compression molding or injection molding.
③ High-precision cutting and thread processing using CNC machine tools to ensure dimensional accuracy.
④ Surface electroplating or hard coating treatment to reduce thread wear and improve surface finish.
⑤ Performance testing and quality control, and provide ISO certification.
