4006 T3 round aluminum sheet has a large thermal expansion coefficient, high high temperature strength, and good high temperature corrosion resistance. For machining forged pistons. It is a building material, a forging material for mechanical parts, and a welding material; 4006 T3 round aluminum sheet 1. High wear resistance. Aluminum-silicon alloy has high wear resistance. With the increase of silicon content, the hardness and strength of aluminum-silicon alloy will increase accordingly. 2. Small coefficient of thermal expansion. Any material will expand at high temperature, which limits the application range of most materials. The aluminum-silicon alloy has a small thermal expansion coefficient and can work in a high-temperature environment. 3. Easy to cast. Among the cast aluminum alloys, 4-series aluminum-silicon alloys account for more than 90%, which shows the superior casting performance of aluminum-silicon alloys.
