Aluminum silicon alloy is a forged and cast alloy mainly composed of aluminum and silicon. Generally, it contains 11% silicon. Simultaneously add a small amount of copper, iron, and nickel to improve strength. Density is 2.6~2.7g/cm3. The thermal conductivity coefficient is 101~126W/(m · ℃). The Young's modulus is 71.0 GPa. The impact value is 7~8.5J. Fatigue limit ± 45MPa. Aluminum silicon alloy is the most important among all aluminum casting materials to date.
Usage
They are suitable for all casting processes and have excellent casting performance. The important application areas are automotive parts, including engine blocks and pistons. In addition, their application as high-energy thermal storage functional materials for electric vehicles is currently receiving attention.
Production method:
Electric heating method
Features:
1. High castability, fluidity, corrosion resistance, ductility, low density.
2. Suitable for large castings and can operate under heavy load conditions.
3. It is considered an alloy that cannot be heat treated, but adding Mg and Cu can enable it to undergo heat treatment, such as A Π 4 alloys.
4. Strengthening through solid solution treatment, such as adding 0.01% sodium (in the form of sodium fluoride [NaF] and sodium chloride [NaCl]) to the melt before casting.
