And a flame crystalline, metal material to form a moisture absorption resistance, corrosion resistance and metal material plastic working aqueous lubricant and a lubricating film excellent in processability

摘要

PROBLEM TO BE SOLVED: To provide an aqueous lubricant for plastic working of a metallic material, capable of forming a lubricating film having the hardly crystallizable property, and excellent in the hygroscopic resistance, the corrosion resistance and the plastic workability.;SOLUTION: The aqueous lubricant for plastic working of a metallic material contains alkaline metal borate salts (A), wherein the alkaline metal borate salts (A) contain lithium borate; the molar ratio of lithium to all the alkaline metals in the alkaline metal borate salts (A) is 0.1 to 1.0; and the molar ratio (B/M) of boron (B) to alkaline metals M in the alkaline metal borate salts (A) is 1.5 to 4.0.;COPYRIGHT: (C)2012,JPO&INPIT
