Pratt & Whitney Approves Houghton Metalworking Fluid

Houghton International, Inc. (Valley Forge, PA), a global leader in metalworking fluids and services, has received approval from Pratt & Whitney (East Hartford, CT), a United Technologies company, for the use of their Hocut® 4940 Metalworking Fluid in the production of its aircraft engines and military power units under 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. The semi-synthetic advanced metalworking fluid is 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.

“It is truly a global formulation that enables aerospace companies to achieve a step-change in productivity while incorporating new environmental requirements,” said Gary Dukus, the business development manager of aerospace for Houghton. “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, it 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. Hocut 4940 also provides performance advantages that support the Pratt & Whitney approval, including increased tool life, longer sump life, higher productivity, improved quality of surface finish, and reduced backlogs, all contributing to the lowest total cost of operation.

Houghton has been a supplier of advanced fluid solutions for global aerospace manufacturers’ most demanding metalworking operations for decades. The company operates research, manufacturing and office locations in 33 countries around the world delivering solutions that increase productivity, reduce operating costs and improve product quality for our customers.
