Abstract: A permanent magnetic alloy powder includes rare earth elements, iron, boron, aluminum, copper and carbides. The rare earth elements include neodymium, and account for 24 to 30 parts by weight. Iron accounts for 65 to 72 parts by weight. Boron accounts for 0.8 to 1.2 parts by weight. Cobalt accounts for 2.8 to 3.2 parts by weight. Aluminum accounts for 0.2 to 0.6 parts by weight. Copper accounts for 0.1 to 0.4 parts by weight. The carbides account for 0.1 to 0.4 parts by weight. The particle size of the permanent magnetic alloy powders is 10 μm to 70 μm, and the grain size of NdFeB phase in the permanent magnetic alloy powders is less than 5 μm. Through the selection of alloy material ratio and manufacturing process, the processability and formability of permanent magnetic alloy materials can be effectively improved, suitable for metal injection molding and 3D printing production.

Abstract: A multi-element alloy material consists of Al, Cr, Fe, Mn, Mo and Ni. From an outer surface to a center of the multi-element alloy material exhibits a hardness gradient from high to low. A method of manufacturing a multi-element alloy material with hardness gradient includes melting and casting metals with a metal combination of Al, Cr, Fe, Mn, Mo and Ni to form an alloy body, subjecting the alloy body to a homogenization treatment, and subjecting the homogenized alloy body to a high temperature treatment to perform precipitation hardening at surface of the alloy body by heating, thereby forming a multi-element alloy material having hardness gradient.
