Heat Treatment and Other Processing Techniques
- Heat Treatment:
Because of the high silicon in your A413 Aluminum Alloy, there are few or no heat treatment options since hardening processes are restricted. However, its silicon supports great stability of shape during casting.
If you apply anodizing or e-coating as surface finishes, your parts gain resistance to rust and will also make your parts durable and visually appealing.
- Machining:
You cast with A413 aluminium alloy, you will discover that the material machines well and makes achieving the needed tolerances simple for your product.
- Vacuum Impregnation:
Porous areas in your castings can be sealed with vacuum impregnation, which ensures your parts are leak-proof and important requirement for components holding fluids or other types of fluid pressure.
