Abstract
Abstract A metal drawing compound is described which is formed by dipping or otherwise coating metal drawing stock with an aqueous soap-borate composition having a pH in the range of from about 7.6 to less than about 9.0. The solution can be allowed to dry on the workpiece, or can be used as a wet film and then drawn conventionally. In a preferred embodiment of the invention the soap-borate composition is prepared by admixture with a borate compound selected from the group consisting of potassium pentaborate, ammonium pentaborate and sodium octaborate in neutral pH water of solution.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
88 words
In a process of working metal pieces, the steps which comprise (1) coating the surface of the metal with a drawing compound by applying thereto an aqueous solution of a mixture of a soap and a compound which produces a borate ion, the soap and the borate ion producing compound having relative proportions of from about 1:4 to about 4:1 and said aqueous solution having a pH within the range of from about pH 7.6 to less than about pH 9, and thereafter (2) working said metal piece.
Claim 2
Dependent Claim
88 words

Claim 4
Dependent Claim
25 words
The process of claim 1 wherein the borate ion producing compound is selected from the class consisting of potassium pentaborate, ammonium pentaborate and sodium pentaborate.
