The invention discloses a composition of aluminum and aluminum alloy hot forging lubricant. The composition adopts 150BS II type base oil as base oil to cooperate with various composite additives including an oily agent, an antioxidant, an anti-wear agent, a defoaming agent, a metal passivator, a friction modifier, a filler and an antirust agent. The lubricant composition disclosed by the invention can bear a very high pressure, can be effectively preserved between a mold and a forged piece, and has good adhesion performance, oxidation resistance, dispersion and carrying capacity to ensure that a uniform and continuous oil film layer is formed between a forging die and a forged piece, the friction coefficient during forging is reduced, the adhesion and coking between the forged piece and the forging die can be reduced, and the composition also has good cooling and heat insulating properties and good film-forming property and abrasion resistance.
