Tungsten Ring

Tungsten Ring In vacuum furnaces that often exceed 1500 °C, or in high-speed bearings with tens of thousands of revolutions per minute, ordinary alloys tend to collapse due to thermal fatigue or wear. Tungsten Ring (Tungsten Ring), with its astonishing density (19.3 g/cm ³) and hardness close to diamonds, is becoming the last line of defense against high temperature and corrosion in modern industry.

1. Basic performance: reshaping the power of the physical boundary Tungsten (W), as a metal at the melting point on Earth, endows tungsten rings with a near-"immortal" physical property:

Extraordinary high temperature resistance: The melting point is as high as 3415 °C, and it can still have extremely high mechanical strength in the fervorization state.

Extremely high elasticity modulus: The elasticity modulus of tungsten is as high as 411GPa, ensuring that the tungsten ring hardly deforms under great pressure.

Excellent ray shielding: Under the same thickness, tungsten's shielding ability to high-energy rays far exceeds that of lead, and it is the first choice in the field of clean medical treatment and nuclear energy.

2. Chemical composition and technical indicators (Pure & Alloy Options)

We provide a full range of options from high-purity tungsten to special tungsten alloys to match the needs of different working conditions:

3. Lean process: from nano powder to dense ring The birth of every tungsten ring is an extreme challenge to the powder metallurgy process:

High-pressure Isostatic Pressing (Isostatic Pressing): Ensure the consistency of blank density and eliminate internal microscopic pores.

High temperature vacuum sintering: After dozens of hours of sintering in reduction, the tungsten particles are completely crosslinked.

Precision grinding and CNC machining: Since tungsten is hard and brittle, we use diamond tools and slow feed grinding technology to control the tolerance to the micron level.

5. Implementation standard: ASTM B760 (tungsten plate/ring standard) or AMS standard on demand.

Surface Treatment: From Mirror to Functional Coating

Ground: Eliminates machining stress patterns and provides excellent sealing fit.

Polished: To achieve the mirror effect, high-speed motion coefficient.

Blasting/Electrolytic Treatment: Surface area or specific surface activity to facilitate brazing or bonding.

6. Core strength: Why do senior purchasers prefer our products?

Anti-Stress Cracking technology: The unique annealing process ensures that the tungsten ring does not break brittle when it comes to the thermal expansion and contraction cycle.

Ultra-High Density Consistency: The actual measured density of each tungsten ring is infinitely close to the theoretical value, ensuring dynamic balance performance in the filed of centrifugal applications.

Life-Cycle Cost Performance: Although the initial cost is higher than steel or nickel, its service life is usually as more 10 times than that of the latter, greatly reducing downtime and maintenance time.

7. Application areas: covering sea, land, air and nuclear

Semiconductor and vacuum: As a shielding ring for ion implanters or a heat insulation support for high-temperature vacuum furnaces.

Medical technology: Miniature multi-leaf collimator (MLC) assemblies for CT machines, linear accelerators, and radioactive source container seals.

Precision machining: high-speed spindle balance ring, anti-seismic tool arbor weight parts and EDM electrodes.

Oil drilling: Used as a wear-resistant bushing and weighted sealing ring in extremely deep wells.
