As a leading firm and well know powder supplier in China, SHANDONG JIANSHU INIDUSTRY CO.,LTD also know as Kingsman Alloys Manufacturing Corporation(K.A.M.C) has been engaged in atomized powders over fifty years. Vacuum melting gas atomizers & high-pressure water atomizers and full testing instruments are well equipped. At present, six categories and over 100 types high quality Fe-base, Ni-base, Co-base, Cu-base and other customized fine alloy powders are produced, which include soft magnetic alloy powders, super fine stainless steel and low alloy steel powders for metal injection molding (MIM) parts, industrial diamond catalyst powders and pre-alloyed matrix powders for diamond tools, high speed steel powders and super alloy powders for additive manufacturing, SLS 3D industrial printing, HIPPED products, thermal spray coating / welding / brazing powders for hard face. Characteristics - High purity, low inclusion - Spherical and irregular particle shape customized - using effective way to successfully reduce the apparent density of high temperature alloys powder and make pressing no longer difficult - Low oxygen content Alloy 718/UNS NO7718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300째F. The sluggish age-hardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling. This alloy has excellent weldability when compared to the nickel-base superalloys hardened by aluminum and titanium. This alloy has been used for jet engine and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.
