Specialized Lightweight Architecture
While solid brass is the commercial standard, specialized architectural applications (structural glass partitions, aircraft cabin doors, marine superstructures) specify Hard-Anodized Aluminum (6061-T6 / 7075-T6) cylinder bodies.
Engineering Properties
- Weight Reduction: 65% lighter than solid brass ($2.7\text{ g/cm}^3$ vs $8.5\text{ g/cm}^3$).
- Type III Hard Anodizing: 50 μm hard anodic oxide layer achieves surface micro-hardness of 400 to 500 HV, resisting internal pin chamber wear.
- Corrosion: Excellent atmospheric corrosion resistance with zero galvanic leaching.
Frequently Asked Engineering & Selection Questions
Q1: Are aluminum lock cylinders durable enough for commercial use?
Yes, when manufactured from 6061-T6 alloy with Type III hardcoat anodizing, aluminum bodies deliver excellent wear and corrosion resistance.
