Gr1 Titanium Rod Description
1. Introduction
Gr1 titanium rod is made of A00 CP titanium, which belongs to α-type commercially pure titanium and the purest grade in industrial applications.
Chemical composition: titanium content≥99.5%, impurities (Fe, O, C, N, H) very low content
Grade characters: Gr1 titanium rod has the best ductility, but the strength is lower than that of other grades.
Rod form: Round rods, square rods, hexagonal rods, and other shapes produced through processes such as hot rolling, forging, and cold drawing are the most basic forms of titanium materials.
Produce process & equipment: The commercially pure titanium rods are made of high-purity titanium sponge, ingots produced by vacuum arc remelting two or more times, manufactured by forging billets, hot rolling, or forging into rods; and stress-relief annealing, followed by acid pickling, turning or grinding, straightening, precision cutting, and non-destructive testing before shipment. It features a uniform microstructure, good ductility, excellent corrosion resistance, and high dimensional accuracy.
2. Finished & Quality Control

Annealed state |
Fully annealed after hot/cold working to relieve stress. |
The best ductility, superior weldability, and the most consistent performance; the top choice for general-purpose applications, suitable for all forming, welding, and corrosion-resistant applications. |

Hot work state |
Delivered directly after hot rolling/hot forging, without annealing. |
Slightly higher strength and slightly lower ductility; used for structural components that do not require high formability and are machined directly. |

Cold work state |
Not annealed after cold drawing/cold rolling. |
High strength, low ductility; used exclusively for small-diameter precision shafts and rods that do not require deep forming. |
