PVD bronze finish: 304 stainless steel substrate with atomic-level ceramic coating (ASTM A240, ASTM B968). Fadior specifies 304 food-grade stainless steel (18-20% Cr, 8-10.5% Ni per ASTM A240) as the substrate for all PVD bronze applications, selected for its pre-existing passive oxide layer that provides corrosion resistance independent of the coating system.
The Physical Vapor Deposition process occurs in Salvagnini-integrated vacuum chambers operating at 10⁻³ to 10⁻⁵ mbar, where solid titanium-aluminum or zirconium targets are ionized via cathodic arc evaporation. Reactive gases—nitrogen at 150-300 sccm flow rate with argon carrier—combine with vaporized metal to form TiAlN or ZrN ceramic lattices bonded at 0.3-5 microns thickness directly to the steel surface.

Overview
Fadior engineering selects TiAlN for interior applications requiring maximum hardness (2400 HV target) and ZrN for enhanced UV stability in exterior-rated installations; the specific gas ratio determines optical interference patterns that yield warm bronze (L* 45-55, a* 8-12, b* 18-25 per CIE Lab) without organic pigments. This atomic bonding distinguishes PVD from electroplating, which relies on 5-25 micron copper-nickel underlayers susceptible to galvanic corrosion and interlayer migration.
The ceramic-metal composite structure achieves 2000-2400 HV surface hardness per ASTM B968—10.7-12.8× harder than untreated 304 stainless steel (187 HV)—while retaining the substrate's ductility for forming operations.
Material note
This finish shifts how the stainless steel surface reads, from warmer and softer to cleaner and more reflective.
Material note
The finish changes what you see and touch, while the stainless steel body underneath continues to carry the system.
Material note
The right finish depends on light, touch frequency, maintenance expectations, and how decorative the room should feel.
