Rhoxon EMCOOL 739EP is suitable for processing various types of aluminum without discoloration, including high-silicon aluminum alloys, 7-series aerospace aluminum, ADC aluminum, engine casting aluminum, and others. Some special workpieces may require continuous machining on the machine for 8 hours or longer, and the machined and non-machined surfaces remain as bright as new. Its powerful corrosion resistance relies on the special protection of the latest phosphate-free aluminum corrosion inhibitor. Its outstanding lubricity can meet most cutting processes other than grinding, such as precision reaming, tapping, and other demanding processes. Excellent rust resistance, long service life, and low foaming, suitable for standalone machines and central circulation systems.
