PURPOSE:To obtain a powdery lubricant for forging of aluminum alloys, capable of producing high-quality forgings by blending a lubricant base material composed of an inorganic compound and having a specified shape with an organic compound, also having a specified shape and capable of giving an adhesive force to the base material. CONSTITUTION:An objective powdery lubricant obtained by blending (A) a powdery or granular lubricant base material composed of an inorganic solid compound used as a lubricant, preferably, e.g. boron nitride, fluorides, talc, mica, metal oxides or silicon nitride with (B) an organic compound component preferably composed of plural metal soaps, plural polymers, a liquid compound or a paste-state compound capable of giving an adhesive force to the component (A) and powdered and granulated with a cyclodextrin compound, provided that both the components (A) and (B) have a powdery or granular shape or that the above-mentioned component (A) is coated with the component (B). |
