CEWELD Powder PTA DUR 12 is a cobalt-base metallic powder with spherical shape designed for plasma-transferred-arc (PTA) welding process. It is especially suited for hardsurfacing of parts subject to a combination of erosion, corrosion, cavitation, pressure, impact and abrasion and high temperatures.
Such as: Internal combustion exhaust valve, Valve plugs & seats, Pump sleeves, Bearing areas, Saw blades and tips, Saw teeth, Chain saw guide bars, and other Wood cutting tools, Knives, Scissor blades, Molten glass cutter
Twist rolls, Hot extrusion dies
