Anodising Explained: Why Your Metal Wallet Colour Fades (and How to Stop It)
Anodising is what gives aluminium wallets their colour. Cheap anodising fades in 6 months. Proper anodising lasts 5+ years. Here is how it works and what to specify.
How Anodising Works
Anodising electrochemically converts the aluminium surface into a durable oxide layer. Dyes are absorbed into this layer before sealing. The quality of the seal determines colour fastness.
What to Specify
- Type II anodising (decorative) or Type III (hardcoat, 2–3x thicker)
- Sealing quality: nickel acetate or hot water seal
- Colour: black, gunmetal, silver, blue, red, gold
Why Cheap Wallets Fade
Cheap anodising skips the sealing step. The dye washes out from skin oils and UV exposure. Our anodising passes 48-hour salt spray and 500-hour UV test.
Type II vs Type III Anodising
| Factor | Type II (decorative) | Type III (hardcoat) |
|---|---|---|
| Thickness | 5–25 μm | 25–150 μm (2–3× thicker) |
| Wear resistance | Good | Excellent |
| Colour range | Wide (dyed) | Narrower (often darker) |
| Best for | Colour-first consumer wallets | Heavy-use or tactical wallets |
Finish Options Compared
| Finish | Look | Durability | Best for |
|---|---|---|---|
| Anodised (Type II) | Matte or satin colour | High | Everyday aluminium |
| Sandblasted | Fine matte | Medium | Tactical / EDC |
| Brushed | Linear grain | Medium | Premium metal |
| PVD coating | Metallic film | Very high | High-wear accents |
FAQ
Q: Does anodising affect RFID shielding?
A: No. The oxide layer is nanometres thick. The aluminium substrate does the RFID blocking.
Q: What colours are available?
A: Standard: black, gunmetal, silver. Custom: any Pantone, MOQ 1,000 pcs per colour.
Q: How long does anodising take?
A: 3–5 days as part of production. No extra lead time.

This article was written by our production and QC team — the people who spec tolerances, run the finishing line and inspect every batch. Where it states a capacity, a pull force or a lead time, it comes from a measurement we made, not a supplier’s catalogue. If a number here disagrees with what your own supplier told you, tell us; several of these articles started as a correction from a buyer.
