According to its strength, titanium alloys can be divided into three categories: low strength, medium strength and high strength. This article will introduce the characteristics of each type of titanium alloy and its specific application in detail.
What is titanium alloy?
Titanium alloy refers to an alloy formed by adding other elements (such as aluminum, vanadyum, molybdenum, vesaire.) based on titanium. Titanium alloys have high specific strength and good corrosion resistance, and their properties can be changed by adjusting the composition to adapt to different application requirements.
1. What are the factors that affect the strength of titanium alloys?
The strength of titanium alloys is influenced by their chemical composition, ısıl işlem, and mechanical working processes. Titanium alloys are generally classified into low-strength, medium-strength, and high-strength categories, each serving different purposes based on their properties.
