1. Composition and characteristics: High silicon aluminum alloy (such as ZY-AlSi25) with a silicon content of 18%-25% is used to form a matrix with uniform silicon particles through precision die-casting process. The surface hardness reaches HV380-400, the friction coefficient is as low as 0.15, and the wear resistance is improved by more than 60% compared with traditional cast iron.
2. High temperature resistance: The high content of silicon and silicon dioxide dispersion strengthening give the material positive high temperature resistance (working temperature range -30℃~180℃) and corrosion resistance, suitable for high pressure compression scenarios
