tungsten disc ring tungsten sheet ring
Tungsten disk ring is a ring composed of the hardest metal on Earth, far harder than titanium ring and more durable than gold ring. This type of ring is usually used for sealing, disc rollers, instruments, etc. The hardness of tungsten disk rings is extremely high, about 10 times harder than gold, 5 times harder than tool steel, and 4 times harder than titanium.
Due to its extremely high hardness, tungsten carbide can maintain its shape and luminous time for a longer period of time compared to any other ring on the market, hence it is known as the "permanent polishing ring". In addition, tungsten disk rings do not bend and have extremely high wear resistance, making them one of the most wear-resistant rings on Earth.

1. raw material preparation
(Firstly, high-purity raw materials are used to reduce tungsten oxide through a full hydrogen reduction furnace, producing high-purity tungsten powder. )
2. powder mixing
(Next, mix tungsten powder with other necessary alloying elements (such as nickel, iron, cobalt, etc. to form tungsten alloy powder. )
3. forming
(Adding a molding agent to tungsten alloy powder, after mixing, granulation, and vacuum drying, sieving to obtain granular materials)
4. Pressing
(Pressing the granular material into a circular tungsten alloy embryo)
5. Sinter
(The tungsten alloy embryo undergoes steps such as thermal degreasing, sintering, and shaping to form the final tungsten alloy ring)
6. Fine grinding and polishing
(Refine and polish the tungsten ring to improve its surface smoothness and precision)
Stamping die: The application of tungsten steel rings in stamping dies significantly improves the stability and reliability of the dies, and enhances production efficiency and safety. The excellent properties of tungsten steel rings, such as high strength, high hardness, high wear resistance, and high corrosion resistance, enable the mold to maintain high precision and stability during the stamping process, improve product quality and production efficiency, and also extend the service life of the mold, reducing production costs and maintenance expenses.
The common problems with tungsten rings mainly include brittleness of the tungsten electrode caused by excessive current usage, flush fracture, and easy cracking during sharpening.
The main reason for the brittleness and uniform fracture of tungsten electrodes is prolonged use under high current conditions. When the temperature reaches the recrystallization temperature of tungsten grains (1600 ℃), the tungsten grains become round, long, and coarse, leading to the brittleness of tungsten electrodes. The solutions include adjusting the current size, avoiding prolonged use under high current, and selecting appropriate tungsten electrode diameter and angle.
