Quakercool 7000 ALF BAF, already available in Europe, is now available in the U.S. market after chemists reformulated the coolant to meet U.S. aerospace industry requirements. The Quakercool brand of coolant is designed for those aluminum alloys primarily used in the aerospace industry due to its low alkalinity properties. Quakercool is also for use on steel and cast iron.
The coolant has been shown in tests to prevent staining, and Quaker notes its wetting abilities enable “high cutting performance [and] microbiological growth control without biocide addition.” The coolant has also reportedly been shown to uphold tooling cleanliness as well.
Quaker’s coolant is designed to be water soluble, boron-free and amine-free. These qualities ensure environmentally conscious machining operations. Quakercool 7000 ALF has a volatile organic content (VOC) use rating of 13.3 g/L to comply with the South Coast Air Quality Management District (SCAQM) test maximum requirement of 75 g/L.
