The invention relates to a film forming agent for aluminum drawing, drawing for pretreatment of aluminum before, including the following components according to weight percentages: 1 3% sodium fluoride, zinc fluoride 0.1 0.3%, 0.05 0.10% sodium fluoride and residual water. For the aluminum stretch film forming agent using zinc film-forming agent processing aluminum surface, forming film, this can be more easily in the pipe pulling, stretching times of up to 6 8 times, stretching the length of more than 80%, the tensile rate is high, the surface of aluminum tubes after stretching light, no crack, good effect.
