Nickel Powder – for Welding Consumables and Galvanizing


The OH series of Nickel Powders is produced through a hydrometallurgical process, also known as Hydrogen-Reduced or the “Sherritt-Gordon” process. Nickel is precipitated under high pressure and temperature to create a spherical shape with a “cauliflower” surface. Hunter Chemical further processes the raw material, employing screens and other separation methods into particle size ranges for diverse applications.
