Title:
POWDER COMPACT, MANUFACTURING METHOD THEREFOR, AND METHOD FOR MANUFACTURING POROUS SINTERED COMPACT
Document Type and Number:
Japanese Patent JP3800510
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a powder compact superior in handleability, which is needed in manufacturing a porous sintered compact with high porosity.
SOLUTION: The powder compact superior in handleability consists of mixed powders of at least a metal powder and a binder having a property of softening at a low temperature, and includes 2.5 mass% or more of a lubricant for powder metallurgy as the binder, and 40-70 vol.% of the metal powders in terms of volume ratio of the metal powders to the powder compact. By using a proper amount of the binder with the property of softening at a low temperature, even the powder compact with a low occupying volume ratio of the metal powder does not get out of the shape.
