Product Description

Certifications

Kefeng Powder Metallurgy Co., Ltd. is a leading source for industrial supply chain distribution of heavy metal tungsten alloy grades for fabrication and parts applications within various advanced technology industries.  With a nominal tungsten content range from 89% to 97% and the balance primarily of nickel, copper and iron, these alloys provide unique engineering properties.  It delivers greater ductility and better machinability than pure tungsten. Tungsten alloys can be plated or painted to enhance their corrosion protection.

 

Product Description

Refractory Metals And Tungsten Alloys Machined Components is the pure tungsten materials combined with select elements such as Nickel, Copper or Iron to produce Tungsten Heavy Alloys (WHA).  This powder metallurgy process of pressing and liquid phase sintering of Tungsten with these elements results in four classes of Tungsten Heavy Alloys. The four classes are distinguished in ASTM B777-15 by their final density which is based on the nominal percentage of 90% to 97% Tungsten powder.  Classes one, two and three are available in magnetic or non-magnetic composition and class four is available in magnetic composition only.  The magnetic variations use Iron as the binder while Copper is used for non-magnetic compositions. 

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 temperature resistance
2. High impact and crack resistance
3. Shock and corrosion resistance
4. Good modulus of elasticity and high hardness

Application

Kengfeng high-density balance weights 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.

Refractory Metals And Tungsten Alloys Machined Components can be used as the couterweights of following areas:

• Aircraft control surfaces
• Automotive suspension systems
• Computer disc drives
• Engine components
• Golf club weights
• Helicopter rotor systems
• Racing industry
• Ship ballasts
