Minimum Wall Thickness

1. Steel (Mild or Carbon Steel):
   Minimum Wall Thickness Recommendation: 1.5 – 2 times the material thickness, or at least 1.5 mm for thin sections.
2. Aluminum:
   Minimum Wall Thickness Recommendation: 1 – 1.5 times the material thickness, or at least 1 mm for thin sections.
3. Stainless Steel:
   Minimum Wall Thickness Recommendation: 2 – 2.5 times the material thickness, or at least 1.5 mm for thin sections.
4. Brass:
   Minimum Wall Thickness Recommendation: 1.5 – 2 times the material thickness, or at least 1.2 mm for thin sections.
5. Plastics (e.g., ABS, Polycarbonate):
   Minimum Wall Thickness Recommendation: 2 – 3 times the material thickness, or at least 1.5 mm for thin sections.
6. Cast Iron:
   Minimum Wall Thickness Recommendation: 2 – 3 times the material thickness, or at least 2 mm for thin sections.

These recommendations provide a general guideline for ensuring structural integrity and manufacturability. Keep in mind that the specific application, loads, and desired factors of safety can influence the chosen wall thickness. Always consult with material data sheets and consider design constraints before finalizing the wall thickness for a part.
