The invention provides a water-soluble metal working lubricant which is suitably employed particularly in press-working of aluminum material and which is excellent in both working properties and degreasing properties. The water-soluble metal working lubricant includes 85 mass % or less of water (A); 5 to 75 mass % of a metal salt of an organic carboxylic acid (B) wherein carboxylic acid residue has 8 or more carbon atoms in total and the acid/alkali ratio by mole is 1:0.5 to 1.1; 1 to 50 mass % of at least one metal salt (C) selected from among an organic phosphate ester metal salt, an organic phosphite ester metal salt, an organic phosphonate metal salt, and an organic borate ester metal salt, each having an alkyl group having 8 or more carbon atoms in total; and 10 to 80 mass % of a non-ionic surfactant (D).

Water-soluble metal working lubricant

An antifreeze/coolant composition, comprising a) a base material such as water, alcohol, glycol and glycol ether; b) a fluorine compound and c) an inorganic acid.

Antifreeze/coolant composition

A glycol-based coolant composition which provides an excellent metal corrosion inhibition despite its low phosphorus content is disclosed. The glycol-based coolant composition contains: (A) 0.1-5.0% by weight of at least one ingredient selected from group A&prime; consisting of C6-C12 aliphatic dibasic acids and their alkali metal salts; (B) 0.1-10% by weight of at least one ingredient selected from group B&prime; consisting of alkyl benzoic acids and their alkali metal salts; (C) 0.001-0.1% by weight of at least one ingredient selected from group C&prime; consisting of strontium compounds and their alkali metal salts; and (D) 0.1-0.3% by weight of at least one ingredient selected from group D&prime; consisting of phosphoric acids and their alkali metal salts.
