Precision-machined from ultra-sound tested Ti-6Al-4V grade 5 bars. Custom metric dimensions, aerospace thread forms, and surface modifications stocked for rapid delivery to European contractors.
From historic heavy metallurgy along the Sambre River to the modern Aéropole Science Park in Gosselies, Charleroi demands metallurgical resilience. GR5 Ti-6Al-4V titanium bars form the backbone of next-generation manufacturing in Wallonia.
Adjacent to Brussels South Charleroi Airport (BSCA), aeronautics suppliers, turbine maintenance teams, and space equipment sub-contractors require aerospace-certified ASTM B348 / AMS 4928 Grade 5 bars for structural fittings, actuator housings, and rotating components requiring high strength-to-density ratios.
Industrial processors around Dampremy, Marchienne-au-Pont, and Feluy rely on Ti-6Al-4V for specialized valves, heat exchanger ties, and fluid pumps exposed to wet chlorine, organic chlorides, and high-velocity sulfuric emissions where standard duplex stainless steels experience localized pitting.
With direct railway junctions connecting Wallonia across Benelux and proximity to historic racing circuits (Spa-Francorchamps, Circuit Jules Tacheny Mettet), engineering shops utilize our cold-headed and CNC-turned GR5 bars for suspension linkages, wheel studs, and high-frequency rotating assemblies.
GR5 (UNS R56400 / 3.7165) is an alpha-beta dual-phase titanium alloy representing over 50% of the world's total titanium consumption. In engineering installations throughout Charleroi's heavy infrastructure, the primary driver for transitioning from 316L stainless or 42CrMo4 steel to GR5 is its high strength-to-weight ratio coupled with an inert rutile (TiO₂) passivation layer.
Our bars undergo vacuum arc remelting (VAR) to eliminate interstitial impurities such as hydrogen (≤0.015%) and oxygen (≤0.20%), preventing room-temperature delayed embrittlement under cyclic loading. Every heat lot is ultrasonic-inspected according to AMS 2631 Class A1 standards to ensure zero voids, inclusions, or centreline segregation.

Wallonia’s Plan de Relance (Recovery Plan) prioritizes circular aerospace components, zero-emission hydrogen generation along the canal corridor, and lightweight rolling stock. How titanium sourcing is evolving in Hainaut province:
As Charleroi positions itself as an inland hub for green hydrogen production and pipeline distribution, Grade 5 and platinum-coated Grade 2 titanium bars serve as essential materials for high-pressure valve stems, distributor blocks, and anode supports resisting severe cathodic hydrogen charging.
With major traction manufacturing and transit operations based locally, reduction of unsprung mass across modern bogies and pantograph assemblies has spurred a direct substitution of heavy steel forgings with precision CNC-machined titanium components, cutting maintenance cycles.
R&D centers across the Charleroi-Liège corridor are integrating high-grade Ti-6Al-4V round bars as master feedstock for Plasma Atomization and Wire Arc Additive Manufacturing (WAAM), demanding strict chemical homogeneity and low interstitial gas levels (ELI Grade 23 standard).
