Titanium Round Rod
gr7 titanium including 0.12~0.25% palladium, this titanium material is more resistant to crevice corrosion than commercial pure titanium.
Product Introduction
Grade 7 titanium (Ti–0.2Pd) is an alpha titanium alloy known for its excellent corrosion resistance, particularly in mineral acids and strong brines. It exhibits physical and mechanical properties equivalent to Grade 2 titanium, with a small addition of 0.12–0.25% palladium (Pd) to enhance resistance in mildly reducing and fluctuating environments.
At room temperature, it remains a corrosion-resistant alpha phase alloy. It transforms to the beta phase at 913 °C, and returns to the alpha phase upon cooling at 890 °C.

Applications
Aerospace Industry
Shafts, bolts, fasteners, and other lightweight structural components
Chemical Processing Industry
Heat exchangers, tanks, reactors, piping systems, and fittings
Ideal for use in environments with strong acids, chlorides, or brines
Weldability
No preheat or post-weld heat treatment required.
Welding surfaces must be clean and free of grease, oil, dirt, and pencil marks.
Cleaning methods:
Abrasive cleaning, solvent cleaning, or pickling (nitric + hydrofluoric acid).
Use a trailing gas shield with a low hydrogen, oxygen, and nitrogen content to prevent oxidation and embrittlement.
