Abstract
Compositions suitable for use as forging lubricants, especially for hot forging, comprises an aliphatic or alicyclic organic diluent (preferably one which has a high flash point and a relatively high boiling point), graphite and non-Newtonian basic alkaline earth metal complex. The complex is preferably a grease-like or gel-like basic calcium or magnesium sulfonate or carboxylate, or mixture thereof. Basic magnesium sulfonate-carboxylates are especially preferred. These lubricants, when used in hot forging operations, are characterized by their ability to protect the forging die from welding, scoring or other deformation and by their relatively smokeless properties.
