Cu15Si4
metal· Cu15Si4
Cu15Si4 is a copper-silicon intermetallic compound containing approximately 15% copper and 4% silicon, belonging to the family of copper-silicon alloys and intermetallics. This material is primarily of research and specialized industrial interest, valued in applications requiring high hardness, wear resistance, and thermal stability, such as wear-resistant coatings, composite reinforcements, and high-temperature bearing surfaces. It represents an alternative to traditional bronze and brass formulations where enhanced hardness or specific thermal properties are advantageous over standard wrought copper alloys.
