Grade 7 (Ti‑0.2Pd) Titanium

Palladium-Added Titanium Alloy for Extreme Crevice & Pitting Corrosion Resistance

Overview

Grade 7 Titanium, designated as Ti-0.2Pd, is a palladium-modified commercially pure titanium alloy developed by BOZE Metal for ultra-high corrosion resistance in harsh, aggressive environments. This grade is derived from Grade 2 pure titanium with a small addition of 0.2% palladium, which drastically enhances its resistance to crevice corrosion, pitting corrosion, and acid attack, making it ideal for use in chloride-rich, acidic, and high-temperature chemical settings where standard pure titanium grades are insufficient.

While retaining the excellent formability and weldability of Grade 2 titanium, Grade 7 (Ti-0.2Pd) offers superior durability in corrosive conditions, serving critical industries such as chemical processing, pharmaceuticals, desalination, and offshore engineering. BOZE Metal supplies this grade in full raw material forms, with custom precision components available via BOZO CNC-Ti, our specialized brand for titanium CNC machining and OEM manufacturing.
