The raw materials of a safety razor blade include high-carbon stainless steel as the primary material. Optional coatings like platinum or chromium can be added for improved performance, and some blades may incorporate lubricating strips for a more comfortable shave.
| Material Type | Material Examples | Function |
|---|---|---|
| Steel | High-Carbon Stainless Steel (e.g., 3Cr13, 4Cr13, 6Cr13) | - Provides hardness and sharpness for clean cutting. - Superior edge retention. - Resists corrosion (stainless steel). |
| Coating Materials (Optional) | - Platinum - Chromium - Titanium - Polytetrafluoroethylene (PTFE) | - Improve durability, reduce friction (Platinum, PTFE). - Increase corrosion resistance (Chromium). - Enhance strength and longevity (Titanium). - Minimize irritation (PTFE). |
| Lubricating Strips (Optional) | Polymers with Aloe Vera, Vitamin E, etc. | - Enhance shaving comfort - Moisturize skin and reduce friction. |
