Houghton International said it has received approval from Pratt & Whitney, a United Technologies company, for the use of Hocut® 4940 metalworking fluid in the production of its aircraft engines and military power units under the Pratt & Whitney reference PMC 9151.
Pratt & Whitney approved Hocut 4940 for contact with gas turbine engine parts made from a variety of aerospace alloys including aluminum, steel, stainless steels, nickel-based alloys, single-crystal nickel alloys, cobalt-based alloys, magnesium, titanium, and titanium-based alloys.
Hocut 4940 is a semi-synthetic advanced metalworking fluid designed for machining these tough alloys in the most complex metal removal operations, providing high lubricity without the use of chlorinated additives. It is low-foaming with high detergency so it runs clean. It delivers high lubricity at low usage rates and provides high corrosion protection for both parts and machine tools.
“Hocut 4940 is truly a global formulation enabling aerospace companies to achieve a step-change in productivity while incorporating new environmental requirements,” said Gary Dukus, business development manager, Aerospace. “It is especially valuable for aerospace companies with significant international operations because it conforms to all health and environmental regulations including TSCA, REACH, DSL, METI, and PRTR, enabling a single product to be supplied locally to global operations.”
In addition to being chlorine-free, Hocut 4940 does not contain formaldehyde releasers, boron, TEA, DCHA, or any other secondary amines, making it one of the most environmentally responsible fluids available to aerospace manufacturers.
Headquartered in Valley Forge, Penn., U.S.A., Houghton operates research, manufacturing and office locations in 33 countries around the world.
