Product Description
Kengfeng High Melting Points Hardness Tungsten Balance Weights For Aircraft, Helicopters And Instrumentation are compact products ideal for applications where space is at a premium. Based on tungsten heavy alloys (WHA) with density over 60% higher than lead, our balance weights empower us with small-form ballast for maximum weight in the smallest space. This allows for greater positioning flexibility and overall improvements in confined space utilization. Like the tungsten alloy cubes, they 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. 
Product Description
Tungsten Nickel Iron (W-Ni-Fe) High Density Alloy Machined Parts are made by a metal compression molding process. It has good physical and chemical properties. There are basically two series, W-Ni-Fe and W-Ni-Cu. It mainly contains 90%-97% tungsten and the density can reach 16.85-18.8g/cm3. Nickel, iron, and copper act as a binder between tungsten particles, making the material malleable and workable. Compared with W-Ni-Cu, W-Ni-Fe has better mechanical properties and is widely used in the national defense industry. W alloy military cubes are part of the W-Ni-Fe series. Due to its high hardness and high-temperature resistance, it is now increasingly used in military defenses.Characteristics and features
The heavy tungsten alloy material possess 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 density (17-18.75g/cm3)
2. High melting point
3. Wear resistance
4. High tensile strength (700-1000MPa) and goods elongation
5. Good plasticity and machinability
6. Good thermal conductivity and electrical conductivity
7. Low vapor pressure, excellent thermal stability, small thermal expansion coefficient
8. High radiation absorption capacity (30~40% higher than lead), excellent absorption of X-Ray
