Gas Atomized Powders

Since 1970, AMETEK's Specialty Metals Division has been a global leader in the design, development and production of water atomized specialty metal powders. More recently, AMETEK introduced gas atomization processing at our Reading Alloys facility located in Robesonia, PA.

Gas atomized powders offer a more spherical morphology than water atomized powders and typically have lower oxygen content. Typically, gas atomized powders are used in thermal spray, brazing, metal additive manufacturing and metal injection molding applications.

Thermal Spray Powders are used in a variety of applications including Plasma Transfer Arc (PTA), Spray and Fuse, High Velocity Oxy-Fuel (HVOF), Laser Additive. Typically, these applications require hardness, morphology and a particular particle size distribution. AMEKOTE grades are available in a variety of hardness’s: AMEKOTE 20, 35, 40, 50 and 60.

Ametek is a manufacturer of metal alloy brazing powders with compositions of Nickel, Chromium, Iron, Silicon, Boron, and Phosphorous. Key features include corrosion and oxidation resistance, and solidus and liquidus ranges. Brazing powders are used to make brazing pastes. Typical applications supported are the BNi grades 2, 5 and 7: AMEBRAKE 102, 105 and 107.

Additive manufacturing powders for direct laser sintering or electron beam systems prefer a more spherical powder offered by gas atomized powders. Alloys are available in variety of grades including standard 300 and 400 series stainless steel grades: 304, 316L, 410, 420 plus custom alloys.
