Lightweight Structural Architecture
In specialized architectural glass and aerospace cabin doors, solid brass cylinders are too heavy.
Type III Hard Anodizing
- Weight Savings: 65% lighter than brass ($2.7\text{ g/cm}^3$ vs $8.5\text{ g/cm}^3$).
- Hard Anodized Layer: 50 μm oxide coat achieves 450 to 500 HV hardness.
