Powder and oil lubricants are used in metal drawing process to reduce friction between metal and tools.
Oil lubricants:
– Liquid, usually from mineral or synthetic oils
– Reduction of friction, wear and heat
– Suitable for stretching heavy metals such as steel and aluminum
Powder lubricants:
– Dry, from materials such as graphite or molybdenum disulfide
– High temperature and pressure tolerance
– Reducing surface and environmental pollution
