AbstractA clear trend in the PM community for the past years is the development of increasingly more complex parts. Multi-level, tall and high green density parts are favoured in order to obtain the best mechanical performances while keeping the manufacturing costs as low as possible. To some extent, such advances are dependent on the metal powder feedstock. High performance lubricants added to the metal powder mix should, amongst others, promote a superior die-fill and an easier ejection from the die. This article evaluates the behaviour of lubricant PR-2, a high performance lubricant developed by Rio Tinto Metal Powders. A water-atomised steel powder mix containing 2.0% copper, 0.55% graphite and variable amounts of the high performance lubricant was tested on an industrial press. The press was run in fully automatic mode during extended periods of time and the part-to-part weight variation was measured. The powder was also characterised for its die-filling behaviour. The lubricant is compared to other commonly used PM lubricants such as Acrawax C and Kenolube.
