A multipurpose metalworking fluid used by mixing with water at a ratio of 5–10% for the machining (cutting and grinding) of various metals. It is used as a lubricant and coolant in light and heavy chip removal (machining) of metals such as aluminum and copper alloys, mild steel, and cast iron, as well as in the hot extrusion of aluminum bars (non-chip forming processes).
