Abstract:
A lubricant composition suitable for use in a metal or metal alloy deforming process, which composition comprises:(i) at least 75% by weight of an essentially paraffinic base oil having a viscosity at 25.degree. C. as determined by ASTM D 445 of 2.00 to 2.75 mm.sup.2 /s and an evaporation rate as determined by DIN 53170 of from 400 to 700, on a scale where diethyl ether=1;(ii) a major proportion by weight of a polyhydric alcohol ester of an aliphatic acid;(iii) an amount by weight, which is less than that of (ii), of an amine neutralized phosphoric acid ester of at least one aliphatic alcohol as antiwear agent, the weight ratio of (ii) to (iii) being from 1.5:1 to 10:1; and(iv) from 0 up to 1% by weight of an antioxidant.
