As one of the leading titanium product manufacturers in China, Zecheng Metal provides a variety of titanium alloy grades for various industries.

Get Detailed Technical Data

A titanium alloy is a mixture of titanium and other elements, which can include metals like aluminum, vanadium, molybdenum, iron, and others. These alloys are designed to improve the properties of pure titanium, such as:

Strength

Corrosion Resistance

Workability

Heat Resistance

Titanium-6Al-4V (Grade 5): This is the most widely used titanium alloy, combining titanium with 6% aluminum and 4% vanadium. It offers an excellent balance of strength, corrosion resistance, and formability, rendering it perfect for aerospace, medical, and industrial uses.

Titanium-6Al-4V ELI (Grade 23): A version of Grade 5 with lower levels of interstitial elements, making it more suitable for medical implants due to its enhanced biocompatibility.

Titanium-0.2Pd(Grade 7):An alpha titanium alloy made by adding a small amount of the precious metal palladium to commercially pure titanium.It is mainly used in hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid and high-concentration chloride environments.

Titanium itself is not an alloy; it is a chemical element with the symbol Ti and atomic number 22. It is a metal known for its exceptional strength-to-weight ratio, corrosion resistance, and high melting point.However, titanium is frequently used in the form of titanium alloys.

A titanium alloy is a combination of titanium and other elements, which are added to enhance its properties for specific applications. The addition of alloying elements allows titanium to achieve a balance of strength, weight, corrosion resistance, heat resistance, and other characteristics, depending on the needs of the industry or application.

Titanium alloys have excellent strength, especially considering their light weight and corrosion resistance.While not as strong as the highest-strength steels, titanium alloys are often preferred in aerospace, military, medical, and marine applications because they combine strength with low density, corrosion resistance, and the ability to perform under extreme conditions. The specific strength of titanium alloys depends on their composition and heat treatment process.

Titanium is divided into several different grades based on its chemical composition, mechanical properties and application areas. The main grades include: Grade 1, Grade 2, Grade 3, Grade 4, Grade 5 (Ti-6Al-4V), Grade 7, Grade 9 (Ti-3Al-2.5V), Grade 11, Grade 12 (Ti-0.3Mo-0.8Ni), and Grade 23 (Ti-6Al-4V ELI).

Grade 1 Titanium has a purity of up to 99.5%. Among the various grades we offer, Titanium Grade 1 is known for its plasticity and ductility compared to other grades. It not only has ultra-lightweight and excellent forming ability but also exhibits excellent corrosion resistance and high impact toughness, which is particularly suitable for applications that require long-term contact with human tissue or harsh environments.

Grade 3 Titanium's excellent performance characteristics are mainly reflected in its high strength and good corrosion resistance. Compared with the common Grade 1 and Grade 2 titanium, Grade 3 has significantly improved in strength and reached a higher mechanical performance standard. Although its formability is slightly reduced, this does not affect its important applications in many key fields.
