PA63070 Tungsten Spray Powder Ear Muffs • Compatible with most AVS Ergonomic design with angled • Compatible with most AVS upgrades Stronghand Pipe Plier with Adjustable Top Large V Pads Pipe Pliers The convenient way to hold round or square tubes for butt welding Postalloy 63070 is a nickel base selffluxing powder alloy combined with a very special high carbon tungsten carbide grade to produce the highest amount of abrasion resistance possible The matrix that encapsulates the carbides has a hardness of 5560 RC The Tungsten Carbide in CP63070 has a very high hardness with a very dense uniform crystalline structureThe residual stresses are far lower than conventional tungsten carbide providing better toughness and impact resistanceThe particles have almost no micro defects enhancing the wettability characteristics The low fusing temperature of this alloy combined with cobaltfree carbides help to reduce solution alloying andmelting of the carbidesThe tungsten carbide used is this product goes through an oxidation reduction process that reduces the oxidation potential of this alloy This helps to reduce unwanted overspray and gives the operator more control of the puddle
