Choosing the right door handle material affects both aesthetics and longevity. Zinc alloy and aluminum alloy dominate today’s modern door hardware market. But which one fits your project? IISDOO, a trusted manufacturer with 17 years of experience, breaks down the key differences.
1. Material Basics
Zinc alloy – zinc base + aluminum, copper, magnesium. Excellent for die-casting complex shapes.
Aluminum alloy – aluminum base + silicon, magnesium, manganese. Naturally lightweight.
2. Strength & Durability
Zinc alloy offers higher tensile strength (300–400 MPa) and impact resistance. Aluminum alloy provides 200–300 MPa with better flexibility. For heavy daily use, zinc alloy lasts longer.
3. Weight & Feel
Zinc alloy feels dense and premium (~6.7 g/cm³). Aluminum alloy is 60% lighter (~2.7 g/cm³), ideal for minimalist or oversized handles.
4. Corrosion Resistance
Aluminum alloy forms a natural oxide layer, making it perfect for bathrooms, coastal homes, or outdoor use. Zinc alloy requires high-quality plating to prevent oxidation in humid environments.
5. Surface Finishes – At a Glance
| Finish Type | Zinc Alloy | Aluminum Alloy |
| Bright Chrome / Mirror | ✅ Excellent | ❌ Difficult |
