Product Description
From blending of the powder to forming, machining, sintering and to materials testing, inspecting and shipping the finished product - it all comes from our plant in Xi'an, China. For about 28 years, Kefeng has been producing tungsten products for a variety of versatile applications. At present we're expanding our manufacturing capabilities and growing our team to support our clients purchasing on defense field. New specialized products include: tungsten cubes and spheres, in addition to tungsten heavy alloy products and molybdenum and TZM refractory metal materials.
At Xi'an Kefeng Powder Metallurg Co., we manufacture a wide range of tungsten products which includes powder, rod, sheet, blank, tube, block, wire and more. Specific to tungsten cubes, we manufacture finished products that are either: cubed, rounded cubes. Elmet manufactures the following common sizes of cubes of ASTM B777:
| Product Size (mm) WNiFe | Unit Weight (gr.) | Class |
| 4.85x4.85x4.85 | 2.0 | 2 |
| 4.84x4.84x4.84 | 2.0 | 2 |
| 5.55x5.55x5.55 | 3.0 | 2 |
| 6.1x6.1x6.1 | 4.0 | 2 |
| 3.1x3.1x3.1 | 0.5 | 2 |
| 2.45x2.45x2.45 | 0.25 | 2 |
| 3.85x3.85x3.85 | 1.0 | 2 |
| Product Size (mm) WNiFe | Unit Weight (gr.) | Class |
| 4.5x4.5x4.5 | 1.6 | 2 |
| 1.94x1.94x1.94 | 0.128 | 2 |
Characteristics and features
Due to the tungsten alloy's high density, compatibility, and kinetic abilities among other material properties, tungsten cubes are often used in fragmentation settings. We offer a specialized focus on fragmentation settings and our specific offerings include various sizes and weights of cubes for defense and aviation applications.
Characteristics and features
- High temperature resistance
- High impact and crack resistance
- Shock and corrosion resistance
- Good modulus of elasticity and high hardness
As tungsten alloy cubes are small volume with high density, so it can be used in some fields needing the little but heavy parts, like the counter weights of golf club, pinewood derby car, aircraft, helicopter,vehicle, boat and yacht, especially in precision instrument fields: mobile phone vibrator, clock cube, self-winding watches, anti-vibration toll holders, flywheel weights.
