# Metal guide table

**Metal guide table (for MS, Aluminium, CI, SS304, SS316)**

| **Metal** | **Full name** | **Rusting (long-term)** | **Food contact suitability** | **Impact on grinding quality (general)** |
| --- | --- | --- | --- | --- |
| MS | Mild Steel | Yes (can rust if moisture/contact with water) | Not ideal for direct food contact unless properly coated/painted and maintained | Can add rust risk + contamination if coating wears. Better to use SS for contact parts. |
| Aluminium | Aluminium | No rust, but can oxidize/mark with some materials | OK for some uses, but not preferred for spices/food contact in heavy grinding | Can react/blacken with some acidic/salty materials; not the best for long-term spice grinding contact parts. |
| CI | Cast Iron | Yes (can rust; needs care) | Used in some grinding applications, but needs good maintenance | Strong and heavy. If rust forms, it can affect product cleanliness. Needs dry storage + care. |
| SS304 | Stainless Steel 304 | Very high rust resistance | Highly recommended for food contact | Best balance for hygiene + durability. Helps keep powder clean. |
| SS316 | Stainless Steel 316 | Highest rust/corrosion resistance | Best for food contact (premium) | Best for long life, especially if moisture/salt exposure is higher. Premium hygienic option. |
