The coefficient of friction measurement of Material #1 drawn over 5T die radius is shown in Fig. 6. It is clear that friction is highest under dry condition, followed by 1% oil in water emulsion and 100% oil lubrication. It is interesting to note that, in the case of 1% emulsion, the friction increases with time during the test. This could be due to the less viscous nature of the diluted lubricant. It was observed that, with time, the lubricant was squeezed out of the contact area leading to increased coefficient of friction.
