Feature
- High strength: When heat-treated to the T6 temper, A357 is one of the strongest sand-cast aluminum alloys available.
- Excellent castability: The silicon content in A357 improves its fluidity during the casting process, allowing it to be formed into complex and intricate parts.
- Corrosion resistance: It exhibits good corrosion resistance, even in harsh environments like marine applications.
- Weldability: A357 has good welding characteristics, but it typically requires a post-weld heat treatment
