High Quality Tungsten High Heavy Alloy ASTM B777-07 rods/sheet/tubes

Material:W90-97NiFe(Magnetic)&W90-97NiCu(Nonmagnetic)
Density:16.8-18.8g/cm3
  • High density (up to 65% denser than Lead). 
  • Denser materials exist (, pure Tungsten, Gold, platinum group metals) but their use is restricted by availability, workability and cost. 
  • Providing mass where volume space is limited. 
  • Concentrated weight essential where accuracy is required in placement of mass. 
  • Placement of weight in situations where airflow has a significant impact. 
Machinability 
  • Possible, either to press components to shape, or to cut and shape material prior to sintering. 
  • Reducing the amount of final machining necessary to produce the finished component. 
  • Can be machined conventionally and without much difficulty. 
Production Method 
  • Blending of tungsten powder with other metal powders and a bonding agent, cooling and sieving. 
  • Pressing the blended powder to the required shape (allowing for shrinkage during the final processing), and shaping the green part component. 
  • Pre-sintering the pressed components to remove the bonding agent. 
  • Final sintering in the hydrogen fed furnace to fuse the powder particles together. 
  • Supplied in bar, square, round and rectangle sizes are available in rough oversize, or turned or ground to exact requirements. Components can also be produced to customer drawings. 
Thermal Properties 
  • High softening temperature. 
  • Low thermal conductivity and low coefficient of expansion gives the material a high resistance to thermal fatigue. 
  • Excellent soldering erosion resistance to molten aluminium. 
  • Strong at high temperatures with high thermal stability.
