Special Alloy Powders

Our Special Alloy Powders are manufactured using by our unique water atomizing and gas atomizing technology, a combination of best technologies and skills, and vary in size from several μm to 850μm optimum for their use. We also manufacture MIREX Powders, utilizing only mass-production vacuum annealing system in Japan, to meet a wide range of customer needs.

MIREX Powders
MIREX Powders have the characteristics below.
Compared to general water atomized powders, they have:
  1. 1.High compressibility
  2. 2.High formability
  3. 3.Low oxygen
Uses:
  • Powder metallurgy (PM, HIP, CIP)
  • Thermal spraying, Welding
  • Filters
  • Various additives
Fine MIREX Powders
Fine MIREX Powders can control the following:
  1. 1.Varied shapes to spherical shape
  2. 2.Low TAP density to high TAP density
Uses:
  • Metal injection molding (MIM)
  • Electromagnetic shielding
  • Metal composite inductor
  • Paint
  • Various additives
MIREX Gas Atomized Powders
Mirex Gas Atomized Powders have the following features:
  1. 1.Extremery low satellites
  2. 2.Low oxygen
  3. 3.High sphericity
  4. 4.Freedom of particle size distribution
Uses:
  • 3D metal printer
  • Thermal spraying, welding
  • HIP
  • Electronic parts

Precision Castings (Lost Wax Process)

We can manufacture small lost wax products from 1g to 20kg, including designs for complex and thin shapes. We maximize use of our casting technology to minimize your cost with recommended ways to lighten and consolidate your parts. By producing prototypes using 3D printer, we can quickly provide our customers with trial production samples. In addition, using noncontact three-dimensional measuring machine enables prompt measurement of complex-shaped products. We can handle special materials that need vacuum melting.
