In modern machining, the "right" fluid is the difference between a high-precision component and a costly defect. To help you find the optimal match, we categorize our solutions by Material and Industry.

Machining Materials

Precision Machining Materials Chemistry Optimized for Results. We engineer our fluids to match the exact demands of your specific workpiece. From high-speed cooling that manages extreme thermal loads to EP-lubrication for toughest alloys, we deliver the specialized performance your process requires. The following are common materials and their characteristics.

• Aluminum Alloys: Prevents oxidation and "built-up edge" (BUE) for aerospace and automotive parts.
• Steel & Cast Iron: Advanced rust protection and high cooling capacity for heavy-duty machining.
• Yellow Metals (Brass/Copper): Non-staining formulas that maintain metal brilliance.
• Hard-to-Cut Alloys: Superior lubricity for Titanium, Stainless Steel, and Tungsten Carbide.
• Specialty Materials: High washability and rapid sedimentation for Glass and Ceramics.
