Abstract
Abstract An aqueous metalworking composition comprising about 2-20 wt % of a water-soluble polyglycol, about 0.6-12 wt % of a neutralized or partially neutralized alkyl or alkenyl substituted succinic acid, and water. The composition is especially suitable for metalworking operations such as cutting, grinding, turning, milling, and drilling on aluminum and aluminum alloys.
