Materion Brush Performance Alloys produces a number of engineered high performance copper alloys using a patented technology called EquaCast®. The process produces an extremely uniform, fine-grained microstructure and promotes excellent dispersion of alloy elements for high quality, consistent products.

C96900 ToughMet® 3 is a spinodally hardened copper nickel tin alloy, possessing much higher strength and hardness, equivalent to Alloy 25. It has exceptional tarnish resistance at room temperature, and its corrosion resistance is even greater than that of Alloy 25 or ToughMet® 2. It is used for heavily loaded bushings or bearings commonly found in aircraft, off-road equipment and industrial machinery. It is often used for sour oilfield service, and is compliant to NACE MR0175/ISO 15156 with no restriction on hardness.
