High-melting-point tungsten alloy rings are ring-shaped products made of high-density tungsten-based alloys (also known as high-density tungsten alloys) with tungsten (W) as the main component (usually over 90%), and small amounts of nickel (Ni), iron (Fe), copper (Cu), or other elements (such as Co, Mo) added.
1. Key Characteristics of High-Melting-Point Tungsten Alloy Rings
High Melting Point: Tungsten has a melting point of approximately 3422°C, yet the alloy maintains extremely high temperature resistance, remaining structurally stable even at high temperatures.
High Density: The density is typically 16.5~18.75 g/cm3 (close to or equivalent to gold), about 1.7~2 times that of steel. This makes it a typical high-density product, achieving a large weight in the same volume, suitable for applications requiring a high center of gravity or limited space.
Other properties: High strength, high hardness, wear resistance, corrosion resistance, good machinability, excellent radiation shielding ability (absorbs gamma rays, X-rays, etc.), low coefficient of thermal expansion, non-toxic and environmentally friendly (can replace toxic materials such as lead).
2. Common Applications of High-Melting-Point Tungsten Alloy Rings
Radiation Shielding and Medical Use: Used as collimators and radiation shielding components in nuclear medical equipment, effectively attenuating radiation and protecting healthy tissues.
Industrial Sealing and Wear-Resistant Components: Such as sealing rings, bearing rings, valve components, etc., suitable for high-temperature, high-pressure, corrosive, or abrasive environments (such as petrochemical, power, and aero-engine components).
Counterweighting and Balancing: Balance rings in aerospace, automotive (crankshaft counterweights), gyroscopes, and inertial navigation systems, utilizing high density to achieve miniaturized counterweighting and vibration suppression.
Jewelry and Decoration: Tungsten alloy rings, etc., are often used as durable jewelry due to their scratch resistance, corrosion resistance, non-fading, hypoallergenic properties, and long-lasting luster (sometimes gold-plated or surface-treated).
Other: Special applications such as military and nuclear industry shielding components, fishing gear counterweight rings, etc.
