Houghton International has received approval from Pratt & Whitney for the use of Hocut 4940 metalworking fluid in the production of its aircraft engines and military power units.
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.
A semi-synthetic metalworking fluid, Hocut 4940 is designed for machining tough alloys in complex metal-removal operations. It is low-foaming with high detergency and high lubricity and provides 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, Houghton's business development manager. "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. It 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.
