Development of high density tungsten alloy products
Advantages / Salient Technical Features
• Sintered products up to 18.5 g/cm3
• Cubes, cuboids, rods, etc., can be made
• Excellent surface finish and desired microstructure
• State-of-the-art processing facilities to carry out the
batch processing
Problem being addressed
• Optimization of powder mixing, granulation, de-
binding, pre-sintering
• The sintering cycle for desired densification in the
products
Environmental Considerations (if any)
• Efficient utilization of Cr ore fines which otherwise
cause environmental hazards
Major Raw Materials to be Utilized
• Tungsten metal powder
