Advanced Metalworking Fluid Designed for Tough Alloys; Wins Approval from Aerospace Manufacturer

Houghton International's metalworking fluid, Hocut 4940, has been approved by Pratt & Whitney 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.

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.
