Product Description

High Density Machinable Tungsten Alloy custom sem-finished parts are typically supplied to meet the requirements of ASTM-B-777 Class 1, 2, 3, and 4, MIL-T-21014, AMS-T-21014, AMS 7725 Type 1 and Type 2.  Custom grades available upon request and per customer specifications.

Xi'an Kefeng can supply alloys ranging from 90% to 97% Tungsten and contain nickel, copper and or iron binders for applications where high density and machinability are required. We can supply magnetic as well as non-magnetic Tungsten Alloys.

High Density Machinable Tungsten Alloys typical applications include weights, ballast, balancing rotating systems for aerospace and race cars, boring bars, sinker bars, crank shafts, radiation shielding, medical imaging, high precision tools, darts, lead replacement, collimator, and oil and gas drilling applications.

Properties

   
   - Low thermal expansion

   - High Density

   - Radiation Absorption

   - High thermal and electrical conductivity

   - High arc resistance

   - Hardness and Wear Resistance
 

Application

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.
