• UK BS

The comparison table not only lists the corresponding grades in different countries, but also provides detailed information on the chemical composition and properties of each alloy. It aims to offer authoritative and convenient reference for engineers, procurement professionals, and researchers, helping to facilitate material selection and application globally.

Through this comparison table, you can easily compare and convert between different standards, ensuring the selection of the most suitable material for international projects, improving work efficiency, and reducing communication costs.

We are committed to providing the most comprehensive and accurate titanium and titanium alloy grade information. We hope this comparison table will become a valuable tool in your work. Below are some of the most commonly used titanium alloy grades to help you get an initial understanding of their characteristics.

Overview of common titanium alloy grades

Grade 1 CP 4

Grade 1 is the softest commercially pure titanium with exceptional ductility and corrosion resistance. It is ideal for environments requiring high formability, such as chemical pipelines, marine equipment, and medical applications. Known for its excellent weldability and impact resistance, it is the top choice for corrosion-resistant environments.
