Custom-Made Tungsten Nickel Copper W93nicu Alloy Tube From America

• 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. 

• 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. 

• 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.
