Titanium Grade 5, also known as titanium CP1, is the strongest of all commercially pure titanium grades, making it a preferred material for applications requiring ease of formability. It combines excellent corrosion resistance with exceptional strength and durability. This grade is most commonly used in the aerospace and chemical processing sectors due to its outstanding performance in harsh environments and its superior resistance to corrosion fatigue in seawater, making it ideal for marine components.

This alloy also demonstrates remarkable resistance to a variety of chemical environments, including oxidizing media, alkaline environments, organic compounds, acids, aqueous salt solutions, and wet or dry hot gases. Additionally, Titanium Grade 5 offers significant resistance to liquid metals, nitric acid, mildly reducing acids, and wet chlorine or bromine gas. With the highest strength among the commercially pure grades, Titanium Grade 5 rivals stainless steels in many corrosion-resistant applications, providing superior corrosion resistance and significantly lighter weight due to its low density.
