WIPO Patent Application WO/2005/095563

A1

Disclosed is a lubricant composition for plastic working which is excellent in workability, degreasing property and working conditions. The lubricant composition is suitably used in fields of plastic working, particularly in fields of warm press forming, of various metal materials, especially of magnesium-base or aluminum-base nonferrous metal materials. Also disclosed are a warm forming process using such a lubricant composition and a method for producing a warm press-formed metal material. The lubricant composition for plastic working contains a solid lubricant and (B) at least one selected from (i) calcium sulfonates and (ii) non-volatile compounds, and the mass ratio between the component (A) and the component (B) in the composition is from 90:10 to 10:90.
