Gunmetal vs Brass – Comparison Table
| Feature / Property | Gunmetal (Lead‑Free) | Brass |
|---|---|---|
| Corrosion Resistance | Excellent – ideal for aggressive or high‑chloride water | Moderate – can suffer dezincification in poor water conditions |
| Material Stability | Very high – strong and dimensionally stable | Good, but less stable in harsh environments |
| Potable Water Safety | Fully lead‑free and WRAS‑approved | WRAS‑approved but may not suit aggressive water |
| Longevity | Outstanding long‑term performance | Good, but lifespan varies with water quality |
| Best Use Cases | Potable water, heating, cooling, industrial, harsh water areas | General plumbing, heating, low‑risk water conditions |
| Cost | Higher upfront cost, lower lifetime cost | Lower upfront cost, higher risk in aggressive water |
