ABSTRACT:
A metal working oil composition having a kinematic viscosity of 20 cSt or less at a temperature of 40.degree. C. is herein disclosed which comprises (A) 10% by weight or more of an n-.alpha.-olefin (e.g. 1-hexadecene) and (B) an overbased sulfonate having a total base number of 350 mg.multidot.KOH/g or more in such an amount that the total base number of the composition is 12.5 mg.multidot.KOH/g or more. The metal working oil composition is particularly suitable as a press lubricant for aluminum alloys, has an excellent mass workability, and is more excellent in coating workability, lubricity, degreasing properties, weldability, etc. than a conventional solid coating type lubricant.
