Description of Tungsten Heavy Alloy Ring
Tungsten heavy alloy (WHA) refers to a tungsten-based alloy containing at least 90% tungsten and 10% of metals like nickel, iron, and copper. It is WHA that distinguishes itself with outstanding thermal performance, great hardness, high bulk density, and many more. Due to such admirable properties, WHA has found numerous applications such as counterweights, radiation shields, and so on.
The WHA products include rods, cylinders, strips, sheets, plates, tips, bars, blocks, spheres, pellets, balls, discs, rings, and tubes. They all have different applications and are used in various fields because of their remarkable attributes, which include: high density, yield strength, hardness, and elongation.
The military industry equipment, machinery manufacturing, aircraft parts, medical treatment, tungsten alloy counterweights, accessories, and many more make use of tungsten heavy alloy rings because of their unparalleled precision.
Features of Tungsten Heavy Alloy Rings
The tungsten heavy alloy possesses exceptional resistance to high temperatures, impacts, cracks, corrosion, and shocks, and is the most suitable for extremely high-temperature applications. The tungsten heavy alloy also has the lowest coefficient of thermal expansion and the best stability in structure for an alloy, as well as geometric configuration.
1. Good tolerance towards elevated temperatures
2. Elevated resistance to cracking and breaking under impact
3. Protection against shocks and other forms of erosion
4. Precise and powerful capture X-rays and gamma rays
5. Elevated value of elasticity and supreme stiffness

FAQ for tungsten heavy alloy ring
1. What is a tungsten heavy alloy ring?
Tungsten heavy alloy rings have two definitions. The first definition relates to tungsten alloy rings. Because tungsten alloys are often referred to as tungsten steel in industrial contexts, tungsten gold rings could also be referred to as tungsten steel rings. The texture of this type of ring is smooth and has sharp lines, and is very favored by businessmen; the second refers to the tungsten alloy rings which have gold plating, meaning gold is superficially applied to the tungsten alloy ring giving it a gold ring's color. This kind of ring can also be called tungsten gold ring.
2. What are the main advantages?
Ultra-high density: 1.7 times the density of lead
Radiation shielding: 30% higher absorption efficiency of X/gamma rays than lead
High strength: tensile strength up to 1200MPa
Machinability: can be precisely ground to a tolerance of ±0.005mm
Environmentally friendly and non-toxic: can safely replace depleted uranium and lead
3. Main application areas?
Medical: radiation collimators, CT scanning components
Military industry: kinetic armor-piercing projectiles, missile guidance systems
Aerospace: gyroscope rotors, satellite counterweights
Industrial: dynamic balancing counterweights, high-performance molds
4. Production process flow?
Powder metallurgy:
Tungsten powder mixed with bonding metal (Ni/Fe/Cu)
Pressing into ring-shaped blank
Sintering at 1400-1500℃
Precision machining: CNC turning/grinding. Final polishing/plating treatment
5. Standard size range?
Outer diameter: 10-500mm
Inner diameter: 5-450mm
Thickness: 2-100mm
