Forged products are generally used in various parts of airplanes, automobiles, electric machines, etc., because of the requirement for the amount of light, they have been gradually changed from iron to light alloys, such as aluminum alloys. In the forging operation, lubricants or lubricants are usually placed between the model and the material to prevent the two from melting and sticking together, making it easier to peel off the forged product from the model. Lubricants for forging aluminum alloys are usually water-soluble lumps made of graphite-added oil-soluble lubricants, synthetic esters, polysilicone oil, graphite, extreme pressure agents, and surfactants. However, in recent years, due to the lightweight of various parts and the advancement of aluminum alloy forging technology, it is required to obtain high-quality lubricants with better workability. In the past, lubricants could no longer meet the above requirements. That is, the oil-based lubricant has problems such as smoke, contamination of the work place, and the risk of fire. In order to prevent water pollution after use, water-soluble lubricants must be equipped with wastewater treatment, and there are various expenses such as costly equipment investment. Therefore, it is extremely eager to develop new forms of lubricants for forged aluminum alloys. In view of the above problems, the present invention has undergone repeated research and conducted various systematic experiments to provide results for the forging of aluminum alloys in order to achieve higher workability without destroying the environment. A lubricant for forged aluminum alloy that can be used for quality forged products. The powder lubricant for wrought aluminum alloy of the present invention uses a solid or inorganic compound used as a lubricant to form a powder or granular lubricant.
