Product Introduction

GR9 titanium rod is a common titanium alloy material, composed of titanium (Ti), aluminum (Al) and tin (Sn) and other elements. It is composed of 90% titanium, 3% aluminum and 2.5% vanadium, and the remaining 4.5% is composed of iron, silicon and other trace elements. The ratio of these elements during the manufacturing process has a significant impact on the performance of GR9 titanium. Our products are diversified, including not only GR9 titanium rods, but also other titanium and titanium alloy tubes, titanium strips, wires, forgings, forged tubes, forged plates, forged bars, round bars, plates, sheets, seamless tubes, and welded tubes , wire, disc, strip, titanium flange, fasteners, etc. We can meet your various purchasing needs, or you can make an appointment with our service staff to specially customize the product specifications and sizes you need.

Grade 9 titanium alloy cold rolling process:

As the feed rate increases, the radial tensile strain and hoop compressive strain in the opening area increase, and the forming load increases, resulting in a reduction in mold life. Excessive feed will also cause the metal to overflow the roller gap, causing cracks or folds.

As the rolling speed increases, both the radial tensile strain and the hoop compressive strain decrease, and the vertical component also decreases.

The friction coefficient increases, the radial tensile strain and hoop compressive strain in the opening area decrease, and the forming load increases. For thick-walled pipes that are prone to internal surface quality problems, it is recommended to increase friction appropriately.

Features and applications :

1.
GR . 9 titanium alloy rod is a high-strength lightweight material with excellent corrosion resistance in a variety of environments, especially in seawater and chloride-containing solutions. Commonly used in the marine and chemical processing industries.

2.
The combination of high strength and low density makes grade9 titanium alloy rods ideal for applications where weight reduction is critical, such as aerospace, medical equipment and sporting goods.

3.
Has excellent mechanical properties. At the same time, the alloy has good elongation and fracture toughness, and can maintain good deformation ability when withstanding external forces.

4.
It has high hardness and anti-wear properties, and is suitable for some high-strength and high-wear resistance occasions.

production, potential

GR9 titanium rods can be processed through:

forging, rolling, extrusion, welding and other processes.

Anti-oxidation performance :

The alloy's anti-oxidation temperature can reach 315°C. At 800°C for 1 hour, the surface oxidation depth does not exceed 0.05mm.

Electrochemical potential :

The corrosion potential in seawater at 50°C is 9.2V (SCE), slightly lower than the 9.6V (SCE) of pure titanium, but at least 1V (SCE) higher than stainless steel.
