6063-T5 and 6063-T6 aluminum alloys: 186-241 MPa tensile strength (ASTM B221), 2.70 g/cm³ density (ASM Handbook Vol 2). Fadior's Material Research Center specifies these architectural alloys for residential framing applications where extrudability, corrosion resistance, and finish compatibility converge.
The 6063 designation per ISO 209-1 indicates a Mg-Si system containing 0.45-0.9% magnesium and 0.2-0.6% silicon, forming Mg₂Si precipitates during artificial aging that strengthen the aluminum matrix without compromising formability.

Overview
The T5 temper—cooled from elevated-temperature extrusion then artificially aged—delivers minimum 186 MPa tensile strength and 145 MPa yield strength per ASTM B221. Fadior deploys T5 for static framing: display niche surrounds, internal shelf supports, and decorative trim where load requirements remain below 50 kg distributed mass.
For dynamic load-bearing components, T6 temper undergoes solution heat treatment at 520°C followed by water quenching and artificial aging to achieve 241 MPa tensile strength and 214 MPa yield strength per ASTM B221.
Density at 2.70 g/cm³—precisely one-third of Fadior's 304 stainless steel bodies at 7.93 g/cm³—enables hinge systems rated for 200,000 cycles (Blum CLIP top specifications) to operate at 60% lower moment load. This weight differential translates to: 12 kg maximum door mass for aluminum-framed 2400×600 mm glass doors versus 34 kg equivalent steel construction, preserving hardware longevity and user ergonomics.
Chemical stability of the 6000 series provides base-metal corrosion resistance in humid environments (wine cellars, coastal installations) before surface treatment application. Fadior's 600M RMB smart factory in Zhaoqing maintains compositional tolerances through automated optical emission spectroscopy (OES) verification on every extrusion batch, ensuring dimensional consistency for glue-free assembly with Salvagnini-bent stainless steel components.
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.
