Introduction To Titanium Grade 4 ELI / UNS R50705

Titanium Grade 4 ELI

MOKSH TUBES & FITTINGS LLP is a prominent manufacturer, supplier, exporter, importer, and stockist of premium-quality Titanium Grade 4 ELI products, including Pipes & Tubes, Pipe Fittings, Flanges, Fasteners, Sheets & Plates, Coils, Wires, Round Bars, Flat Bars, Welding Rods, Wire Mesh, and Custom-Engineered Components that meet the most demanding applications.

Titanium Grade 4 ELI (Extra Low Interstitial) is an unalloyed (commercially pure) titanium that offers a remarkable balance of strength, ductility, and excellent corrosion resistance. It is slightly stronger than Grade 1 but still maintains outstanding formability and weldability. These attributes make it highly suitable for industries requiring strong yet lightweight corrosion-resistant materials—especially in chemical processing, marine environments, medical systems, and aerospace structures. Its ability to perform reliably in oxidizing and mildly reducing environments sets it apart as a versatile and cost-effective solution.
