February 06, 2026
Hostacor™ AL is a phosphorous-free, water-dispersible corrosion inhibitor based on 100% renewable feedstocks which is recommended for steel-and aluminum cutting & grinding emulsions. The product has a low foaming tendency and contributes significantly to lubrication while simultaneously reducing cobalt leaching. Hostacor AL can also be added to existing metal working fluids for steel to upgrade them for machining aluminum.
