What are the main classifications of titanium alloys?

Titanium alloys are divided into three major types: alpha, alpha-beta and beta titanium alloys based on internal crystal structures. Alpha alloys own outstanding high-temperature oxidation resistance and weldability, fit for long-term medium-high temperature working environments. Alpha-beta alloys such as Ti-6Al-4V balance strength and processability as the most versatile grade for mass production. Beta alloys deliver ultra-high tensile strength after aging treatment, ideal for lightweight high-load parts requiring complex cold forming and precise machining processes.
