Rustlick Ultracut AL is a water-soluble oil formulated for aluminum to prevent staining during the machining process. It can be used with metals, including ferrous, nonferrous, brass, bronze and copper, though it is not use on magnesium.

The biostability of the oil makes it highly resistant to bacteria and fungus and with proper maintenance, it can significantly prolong sump life. It contains non-chlorinated EP additives as well as boundary lubricants and creates a light oil barrier that protects the working part and the machine from rust.

It is also especially good for environments with hard water problems since it provides strong emulsion stability.

Rustlick Ultracut AL is available in 5- or 55-gallon containers. It is a light brown viscous fluid in its concentrated form. It can be diluted 10-to-1 to 40-to-1 depending on the application.
