Luxury Rose Gold Metallurgy
PVD Rose Gold combines high-end architectural aesthetics with extreme ceramic hardness, replacing fragile copper electroplating.
Cathodic Arc Deposition
- Stoichiometric Alloy: Co-sputtered Titanium-Aluminum-Nitride (TiAlN) and Zirconium Nitride (ZrN) in nitrogen plasma.
- Performance: Delivers 2500 HV micro-hardness and ASTM B117 salt spray endurance > 1000 hours, completely immune to green copper oxidation.
Frequently Asked Engineering & Selection Questions
Q1: How is PVD Rose Gold applied to lock cylinders?
Titanium, aluminum, and zirconium are vaporized in a high-vacuum plasma chamber to deposit a 2500 HV ceramic rose gold film onto solid brass.
