In this article, three kinds of prealloy powder were developed by water atomization method. The base attribute, pattern, phase composition, differential thermal analysis of powder were researched. Sintered density, hardness, bend strength, Young's modulus were researched as hot pressed sintering temperature changing. By using abrasive wearing equipment upbuilt by the authors, the wear resistance were determined. Green-pressing density, simulated green-pressing strength and bonding momental of high frequency brazing were assayed. SEM corrosion structure and SEM appearance of fracture were observed.
