A metalworking lubricant comprising an oil-in-water microemulsion and containing about 1-30 wt % natural or synthetic oil; about 0.5-30 wt % of a water-soluble surfactant, preferably a nonionic surfactant; about 1-20 wt % of an organic consurfactant, preferably 1,2-octanediol; and about 45-97.5 wt % water containing less than about 1 wt % dissolved inorganic salts. The lubricant is suitable for various metalworking methods, including hot rolling and cold rolling of aluminum and aluminum alloys.

Metalworking lubricant comprising an oil-in-water microemulsion

A parting composition useful for continuously casting aluminum and aluminum alloys and comprising glycerol trioleate and a vegetable oil. Mixtures of glycerol trioleate with castor oil have superior properties compared with parting compositions previously used for continuous ingot casting.

Parting composition comprising glycerol trioleate and vegetable oil

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.

Aqueous metal removal fluid

A parting composition useful for continuously casting aluminum and aluminum alloys and comprising glycerol trioleate, castor oil and a copper corrosion inhibitor. The parting composition of the invention has superior properties compared with parting compositions previously used for continuous ingot casting. The copper corrosion inhibitor prevents deterioration around openings in oil injection rings made from copper.

Parting composition comprising glycerol trioleate, castor oil and copper

A process for continuously casting aluminum and aluminum alloys using a parting composition comprising glycerol trioleate. Both glycerol trioleate and mixtures of glycerol trioleate with castor oil have superior properties compared with parting compositions previously used for continuous ingot casting.
