Product Description

Company Profile

Xi'an Kefeng Metallurgy's refractory alloys such as tungsten heavy alloy WNiFe or WNiCu are manufactured by the powder metallurgy 
techniques of pressing, sintering and infiltrating in a very high degree of uniformity, held in the fine-grained microstructure of the finished
material.  To the user this means an extremely high performance  material which stand us uniformly the most severe applications ranges in:
balance weights, raidiation protection, vibration absorbers, heat transfer, drilling bars.  The tungsten heavy alloys (WHA)'s mechanical 
characteristics have to guarantee the stability and strength in any application case.

All our tungsten heavy alloy products are in accordance with standards of MIL-T-21014, ASTM B777 and AMS 7725.  These tungsten alloys 
can be delivered both as semi-finished or further processing by the customer or complying with the drawing as finished machined component.

Product Description

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 and is made in a particularly high density material, and are widely applied in the fields of aerospace and vehicle industries which are capable to create smallest weights for limited space and balance controlling surfaces and an ideal method for vibration absorption. We are fully equipped with the production lines from raw powder material, sintering,forging to machining finished products of bar, plate, rod, wire and other drawing parts customized.

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.

Application

The high density of tungsten-based alloy weight balance greatly reduces the physical size of the assembly, which makes it easier to control weight distribution and increases the sensitivity of the control mechanism. They are widely used in aerospace, gyroscopes, propellers and helicopter blades or radar equipment and avionics systems, and automotive industry for crankshaft counterweights and chassis counterweights in Formula 1 racing cars or large-scale only engines and the sporting industries as tungsten alloy darts, golf clubs and other applications of weights for balance of aircraft, helicopter rotors and missiles.

Other applications for tungsten heavy alloy machining parts:
 

1. Radiation shielding
2. Containers of radioactive isotopes
3. High performance projectiles for underwater hunting
4. Gyro components
5. Balance weights for racing boats and racing cars
6. The optical industry like microscopes and measuring instruments.
7. Scintillators
8. Photodetectors
