Made in Thailand at KJ Advanced Materials' Prachin Buri Facility. KJ is the manufacturer of ASTM B-777 comliant tungsten alloys.
 
The Metallurgy of Tungsten Heavy Alloys
Tungsten Heavy Alloys (WHA) parts are manufactured from very fine, high purity metal powders – typically tungsten, nickel, and iron. The blended metal powder is compacted under high pressure (up to 30 ksi) to form a specific shape that is very close to the geometry of the final part. WHA can subsequently be subjected to post sinter heat treatment and mechanical deformation to increase tensile properties and create directional micro-structures.
 
Why Use Tungsten Heavy Alloys 
Tungsten Heavy Alloys (WHA) provides a unique combination of density, mechanical strength, machinability and corrosion resistance. These versatile materials provide distinct advantages when compared to alternate high density materials, such as steel and lead.
