Gold-plated tungsten needle is a specially treated tungsten needle whose surface is covered with a layer of metallic gold. This gold plating treatment gives the tungsten needle a series of unique properties, making it widely used in many fields. The following are the main characteristics of gold-plated tungsten needles:
- High corrosion resistance
The gold layer covering the surface of the gold-plated tungsten needle has excellent corrosion resistance. In high temperature and corrosive environments, the gold layer can effectively resist chemical corrosion, oxidation and sulfidation, maintaining the stability and reliability of the tungsten needle. This high corrosion resistance allows gold-plated tungsten needles to have a longer service life in applications such as high-temperature furnace tubes and electronic devices.
- Antioxidation
The gold layer covering the surface of gold-plated tungsten needle has good anti-oxidation properties. In high-temperature environments, oxidation is one of the common problems during the use of tungsten needles. Gold-plated tungsten needles effectively resist oxidation and ablation in high-temperature environments by covering the surface with a gold layer. This antioxidant property improves the service life and reliability of gold-plated tungsten needles in high-temperature furnace tubes, aerospace and other applications.
- Beautiful golden appearance
The gold layer covering the surface of the gold-plated tungsten needle has a noble and gorgeous golden appearance, giving people an elegant and luxurious feeling. This beautiful golden appearance makes gold-plated tungsten needles widely used in decorative fields such as jewelry, handicrafts, etc. At the same time, it also provides beautiful and practical heating elements for some special occasions such as scientific research and industrial production.
- Good electrical conductivity
The gold layer on the surface of the gold-plated tungsten needle has good electrical conductivity. As a metallic element, gold has better electrical conductivity than most non-metallic materials, making gold-plated tungsten needles widely used in electronic devices and other fields. Good electrical conductivity can improve the stability and efficiency of electronic devices, and can also meet the needs of some special occasions such as high-energy ray detectors.
- High strength and hardness
Gold-plated tungsten needles still retain the high strength and hardness characteristics of tungsten because their base is tungsten needles. This high strength and hardness makes the gold-plated tungsten needle have good rigidity and toughness during processing and use, and can withstand stress in various complex environments, ensuring its stability and reliability.
- Good thermal stability
Gold-plated tungsten needles have good thermal stability and can maintain stable physical and chemical properties at high temperatures. This thermal stability enables gold-plated tungsten needles to adapt to various complex high-temperature environments in high-temperature furnace tubes, aerospace and other application fields, ensuring its long-term stability and reliability.
- Low thermal expansion coefficient
Gold-coated tungsten needles have a low thermal expansion coefficient, which means that their dimensions change relatively little when the temperature changes. This low thermal expansion coefficient allows the gold-plated tungsten needle to maintain dimensional stability and accuracy in high-temperature environments, thereby ensuring its reliability and stability in applications such as high-temperature furnace tubes and electronic devices.
- Good wear resistance
The gold layer covering the surface of the gold-plated tungsten needle has good wear resistance and can effectively resist friction and wear. This wear resistance allows the gold-plated tungsten needle to maintain its original shape and size during long-term use, ensuring its reliability and stability.
- Excellent impact resistance
Gold-plated tungsten needles have good impact resistance and can withstand a certain degree of impact and vibration. This impact resistance makes the gold-plated tungsten needle less susceptible to damage or failure due to external factors during use, improving its reliability and stability.
