Micro Tungsten (W) Powder Applications
Micro Tungsten Powder is a versatile material with a range of particle sizes, each tailored for specific advanced manufacturing and industrial applications. Below is a breakdown of how different particle size ranges are utilized:
- 1-10um: Ideal for Metal Injection Molding (MIM) additions and as a raw material for porous tungsten cathode emitters.
- 5-25um: Suited for the SLM process, CT machine X suspected radiation augmented grid (ASG), and thermonuclear fusion reactor diverter heat sinks.
- 15-45um: Applied in LMD laser melting deposition technology and the additive manufacturing of high specific gravity tungsten alloy special-shaped parts.
