aluminum ingot

Aluminum silicon (Al Si) alloy generally has a Si mass fraction of 4%~22%. Due to its excellent casting properties, such as good fluidity, good airtightness, low shrinkage rate, and low tendency to heat, after modification and heat treatment, Al Si alloy has good mechanical properties, physical properties, corrosion resistance, and moderate machining performance. It is the most diverse and widely used type of cast aluminum alloy
