Product Description

China Tungsten WHA WNiFe WNiCu CNC Machining Components Meet With Aerospace Material Specification AMS-T-21014 And Standard ASTM B777

Product Description
Kefeng's tungsten based composite materials possess remarkable superiority due to its high density and good mechanical properties.  They have a good electrical and thermal conductivity.  It can be delivered both as semi-finished product for the further processing by the customer or according to the drawing as finished machined parts.  We, Kefeng Powder Metallury Co., recommends the delivery for the well finished machined product in order to meet with the specific application of our clients' requirements.
 
Our 90W, 93W, 95W and 97W with a percentage of 10%, 7%, 5% and 3% amounts of nickel and iron or nickel and copper offer a solution in a various range of applications requiring concentrated weight or density in a limited space.  Our lead-free components meet legal requirements and recommendations to protect the environment.


WHA Characteristics

Kefeng heavy tungsten alloy material possess the highest melting point of all metals and suitable for extremely high-temperature environment. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability. Kefeng's high-density balance weights are compact products ideal for applications where space is at a premium. Based on tungsten heavy alloys (WHA) with densities over 60% higher than lead, our balance weights empower manufacturers with small-form ballast for maximum weight in the smallest space.

-High thermal conductivity
-Low coefficient of thermal expansion
-Stability in dimension under extremely high temperature environments
-High density, more than twice the steel
-The hardest, most stable and most heat-resistant metals
-Outstandingly high melting temperature
-Fine machinability, whne it is alloyed with copper, nickel, iron to form tungsten-heavy alloys


 
Application Ranges

Balance weights, radiation protection, vibration absorbers, heat transfer, drilling bars. In regars to the absorption of X-ray and gamma radiation, it is in direct proportion to the density of the shielding material because of its high density composites are more than 1.5 times as effective as lead and provide greatly efficient protection, particularly where space is limited.
