Grade 2 vs Grade 5 titanium

There are significant differences between Gr2 and Gr5 in terms of material, properties, application areas and price. The following are the detailed differences between them:

Gr2: Gr2 is a kind of industrial pure titanium, also known as Grade 3. its main component is titanium, the content of which is up to 99% or more, and it also contains traces of carbon, nitrogen, hydrogen, oxygen and other impurity elements, but the content is very low. gr2 belongs to the alpha-type titanium alloy, which is widely used in many fields because of its high purity and stability.
Gr5: Gr5 is a titanium alloy, also known as Ti-6Al-4V or AB-1. It consists of titanium, aluminum, vanadium and other elements, of which the content of titanium is about 90%, aluminum is about 6%, and vanadium is about 4%. gr5 belongs to the α-β type of titanium alloy, which is widely used in the fields of aerospace and chemical industry because of its excellent comprehensive performance.

Mechanical strength and tensile properties, and tensile properties:
Gr2: Due to its high purity, Gr2 has relatively low mechanical strength and tensile properties, but has good plasticity and ductility.
Gr5: Due to the addition of alloying elements such as aluminum and vanadium, the mechanical strength and tensile properties of Gr5 are significantly better than those of Gr2. This gives Gr5 better stability and durability in high temperature and high pressure environments.

Gr2: Gr2 has extremely strong corrosion resistance and can operate stably for long periods of time in a wide range of corrosive media, including seawater, hydrogen chloride and other strong acids and alkali environments.
Gr5: Gr5 also has excellent corrosion resistance, able to resist oxidation, acid and alkali and other corrosive media. In some specific media (such as sulfuric acid and other reducing acids), the corrosion resistance of Gr5 is even better than Gr2.

Gr2: Gr2 can still maintain good stability and strength in high temperature environment, suitable for use in high temperature environment.
Gr5: Gr5 has even better performance in high temperature environments, especially in terms of long-lasting strong creep strength. This makes Gr5 an ideal material for aerospace and other high-temperature working environments.

Gr2: Gr2 is widely used in chemical industry, marine engineering, medical equipment and other fields due to its excellent corrosion resistance and good processing performance. For example, it is used in the manufacture of offshore drilling platforms, chemical equipment, medical equipment and so on.
Gr5: Gr5 is widely used in aerospace, shipbuilding, medical equipment and other fields due to its high strength, corrosion resistance and good processability. Especially in the aerospace field, Gr5 is used to manufacture engine parts, turbine blades and other key components.
