Grade9 Titanium Alloy Ti‑3Al‑2.5V High Strength Cold Formable Titanium
Published by Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd on 2026-10-25
1. Product Identity
Manufactured in Shaanxi Baoji China, Grade9 titanium alloy (Ti‑3Al‑2.5V) is alpha‑beta near‑alpha titanium alloy. It balances high mechanical strength and superior cold forming performance compared with Grade5. Available in multiple forms including seamless tube, round bar, coil strip and custom blanks. Widely applied in marine hydraulic pipeline, bicycle parts, aerospace auxiliary components and high‑strength corrosion‑resistant structural parts. Stock and custom fabrication per drawings are supported.

4. Mechanical & Corrosion Performance
-
Tensile Strength: 930‑1000 MPa; Yield Strength ≥880 MPa; Elongation ≥10%; Elastic Modulus 113 GPa; Density 4.43 g/cm³
-
Corrosion Resistance: Excellent stability in seawater, salt‑spray and chloride‑containing medium; resists pitting and crevice corrosion in marine environment.
-
Processing Feature: Distinct advantage is good cold formability; can be bent and formed without pre‑heating, while Grade5 Ti‑6Al‑4V is difficult for cold forming. Argon‑shield protection required for welding work.
5. Full Size Range
-
Tube: Custom outer diameter and wall thickness for hydraulic tubing application
-
Bar: Round bar diameter range from small size to large forged blank
-
Strip / Coil: Custom thickness & width, support slitting service
-
Custom options: Special tolerance, cut‑to‑length, near‑net‑shape blanks according to customer drawings.
6. Surface Treatment Options
-
Pickling surface: Remove oxide scale after hot working, standard industrial delivery finish.
-
Polished surface: Smooth surface for hydraulic tube inner‑outer requirement.
-
Machined / peeled surface: Remove surface contaminated layer for high‑performance blanks.
-
Degreasing cleaning: Eliminate oil residue for hydraulic system components.
