Chlorinated lubricants, which have been phased out in Canada and Europe, are still used in many metal-forming applications in the U.S. This class of lubricants is under scrutiny in the U.S., so it makes sense to test alternative lubricants now. Evaluating a lubricant for drawing tube requires much more than simply measuring the draw load during a pull. A comprehensive test evaluates ease of cleaning and finished tube quality also.
