product details

Product Description

Kefeng tungsten Heavy Alloy Ring has excellent strength and ductility. We offer a variety of alloy compositions with different densities and mechanical strengths. We produce a variety of heavy metal products: W-Ni-Fe alloy, W-Ni-Cu alloy, W-Ni-Mo alloy.

This product is a tungsten alloy with a tungsten more than 90% refractory metal which have two-phase composites consisting of W-Ni-Fe or W-Ni-Cu to ensure a high density material, which the density ranges from 16.85 to 18.85g/cc, shapes varies from rod, ball, cylinder, block, ring etc. and are usually applied in the fields of military and defense, aerospace, medical and other Hi-tech industries.

1. OD: 50.0mm~200mm; ID: 60.0mm~220.0mm

2. Quality: 17.15~17.85g/cm3 density for tungsten alloy 93WNiFe, Class 2, ASTM B777 standard

3. Property and finishing: Sintering and machining

4. Application: Military, defense and other Hi-tech industries

Characteristics and features

The heavy tungsten alloy material possess the high temperature resistance, high impact resistance and crack, shock and corrosion resistance, also the highest melting point of all metals and suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability.

1. High temperature resistance

2. High impact and crack resistance

3. Shock and corrosion resistance

4. High absorption capacity against X-rays and gamma

5. Good modulus of elasticity and high hardness

Application

All the characteristics of the tungsten heavy alloy rings make it useful in many industries, including military equipment, machinery manufacturing, aircraft parts, medical treatment, tungsten alloy counterweights, and tungsten alloy accessories.
