Brush M220C is characterized by high levels of strength, hardness, and thermal conductivity combined with excellent resistance to wear, corrosion, thermal shock, and oxidation from room temperature to operating temperatures of 1000°F. This alloy is the most recent addition to the beryllium nickel alloys noted for steel-like hardness and strength levels surpassing many of the high strength steel and nickel base alloys. Brush M220C is machined 2 to 3 times faster and has approximately 90% of the mechanical and physical properties of the strongest beryllium nickels. The improved relative ease of fabrication provides beryllium nickel design benefits at reduced cost. More complex detail and improved surface finish can be produced, further expanding areas of application.

As a casting alloy, easily cast-to-size by precision techniques and machined by conventional methods, Brush M220C is of interest to the tool designer and engineer, particularly in the glass industry.
