Tungsten Metal Foil

Due to tungsten metals foil high hardness, high melting point, good performance, low resistivity, small expansion coefficient, small electronic escape work and other characteristics, tungsten processing products can still work normally in high temperature environment.

Tungsten metals foil production process usually uses high purity tungsten powder, processing into a slab, with special rolling technology rolling into tungsten plate, sheet (foil) and other products, tungsten metals foil advantages are better processing performance, low impurity content. In addition, the surface finish of tungsten foils prepared by various deposition methods is high, but the film density is low and the deposition rate is slow. In the process of rolling and mechanical polishing, the work hardening layer and residual stress are easy to occur on the surface of foil film, and there are serious problems such as crystal orientation and dislocation. In addition, machining of tungsten is still difficult because of its high hardness and extreme brittleness. Therefore, electrolytic polishing method is preferred. This method is based on the principle of anode dissolution to remove metal. It is suitable for any hardness of metal and can remove surface hardening, defects and contamination problems.

1. High melting point: Tungsten foil has a very high melting point of approximately 3422°C, making it an ideal choice for high-temperature applications.

2. High density: Tungsten is a very dense material, with a density of approximately 19.3 g/cm3. This makes tungsten foil an ideal material for shielding against radiation.

3. Good thermal and electrical conductivity: Tungsten foil has good thermal and electrical conductivity, making it an ideal material for use in electrical contacts and thermal management.

4. Corrosion resistance: Tungsten foil has excellent corrosion resistance, allowing it to maintain its properties even in harsh environments.

5. High strength and rigidity: Tungsten foil is a very strong and rigid material that can withstand high stresses and strains without deforming.

6. Non-toxic and environmentally friendly: Tungsten is a non-toxic and environmentally friendly material that can be recycled and reused.

Overall, tungsten foil has many desirable properties and advantages that make it an ideal material for a wide range of applications, including aerospace, electronics, and medical devices.
