Titanium materials are divided into pure titanium and titanium alloy. These two materials are widely used in aerospace, military and medical industries due to their unique advantages. How to choose the titanium material suitable for your project, this article will tell you the answer and help you choose titanium materials better.
Composition
Pure titanium, also known as industrial pure titanium or commercial pure titanium, is a silvery white metal. It is a titanium material with a titanium content of not less than 99% and very little impurities. Common grades Gr.1, Gr.2, Gr.3, and Gr.4 are all grades of pure titanium.
Titanium alloy is an alloy based on titanium with other elements added. Common alloying elements include aluminum (Al), vanadium (V), molybdenum (Mo), chromium (Cr), iron (Fe), etc. For example, the titanium alloy grade Gr.5 (Ti6Al4V) is the most commonly used titanium alloy grade.
Performance
Density: The density of pure titanium is relatively low, about 4.51g/cm³. Due to the addition of other elements, the density of titanium alloy varies depending on the alloy composition, but it is generally around 4.5g/cm³, both of which are much lower than the density of steel.
Strength: The strength of pure titanium is relatively low, and its yield strength is generally around 200-300MPa. Titanium alloys can obtain higher strength through processes such as alloying and heat treatment. For example, the yield strength of Ti-6Al-4V can reach about 895MPa, which can meet the needs of many high-strength structural parts.
Corrosion resistance: Pure titanium has excellent corrosion resistance. It can form a very dense oxide film on the surface to resist further corrosion. Similarly, the corrosion resistance of titanium alloy is also very good, but as an alloy, it can add specific metal elements to further improve corrosion resistance in the face of different extreme environments.
Application field
Due to its good corrosion resistance and low strength, pure titanium is mainly used in occasions with high corrosion resistance requirements but relatively low strength requirements, such as containers and pipelines in chemical equipment, as well as some decorations, glasses frames, etc.
Titanium alloys are widely used in aerospace (such as aircraft engine blades, fuselage structural parts, etc.), marine engineering (such as seawater desalination equipment, ship parts, etc.), biomedical (such as artificial joints, dental implants, etc.) and some high-end machinery manufacturing fields due to their high strength, good corrosion resistance and other excellent properties.
