NOVELTY - A lubricant comprises graphene, and polytetrafluoroethylene. USE - Lubricant for stamping die used for stamping magnesium alloy (claimed). ADVANTAGE - The lubricant is suitable for stamping and molding of magnesium alloy strip with high yield, stamping depth, dimensional accuracy, and surface quality, without producing cracks, and folds. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for stamping of magnesium alloy, which involves (i) placing a magnesium alloy thin strip in a heat treatment furnace, annealing at 300-400 degrees C for 0.5-2 hours, (ii) preheating the stamping die at 255-300 degrees C for 0.5-3 hours, applying a lubricant to the stamping die, (iii) removing the heat-treated magnesium alloy thin strip, placing between the concave and convex dies, die casting into magnesium alloy thin strip, and (iv) aging the magnesium alloy strip for 20-40 hours.
