TC4 titanium alloy parts, also known as Ti - 6Al - 4V alloy parts, are widely used in various industries due to their remarkable properties. Composed mainly of titanium, with about 6% aluminum and 4% vanadium, this alloy combines high strength, low density, excellent corrosion resistance, and good biocompatibility. In this article, we will explore the advantages of TC4 titanium alloy parts in detail and their extensive application fields. Understanding these aspects can help industries make more informed material - selection decisions, taking full advantage of the unique features of TC4 titanium alloy parts.
The Composition and Basics of TC4 Titanium Alloy Parts

TC4 titanium alloy parts mainly consist of titanium (Ti), with aluminum (Al) and vanadium (V) as the main alloying elements. Typically, the content of titanium in TC4 titanium alloy is about 89 - 91%. Titanium serves as the base metal, endowing the alloy with excellent corrosion - resistant properties. Aluminum accounts for approximately 5.5 - 6.75% of the alloy. Its addition significantly enhances the strength and hardness of the alloy. ...
... Meanwhile, aluminum can effectively reduce the density of the alloy, contributing to the lightweight characteristics of TC4 titanium alloy parts. Vanadium is present in the alloy at a level of 3.5 - 4.5%. Vanadium plays a crucial role in improving the high - temperature strength and toughness of the alloy. This ensures that TC4 titanium alloy parts can maintain stable mechanical properties in high - temperature environments.
In addition to these main elements, TC4 titanium alloy may also contain trace amounts of other elements. For example, the iron (Fe) content is generally controlled to be no more than 0.3%. Although iron has a relatively small impact on the overall performance of the alloy, strict control of its content is necessary to avoid potential negative effects on the alloy's properties. The oxygen (O) content is also strictly limited to no more than 0.2%. Excessive oxygen content can lead to alloy embrittlement, which seriously affects the mechanical properties and service life of TC4 titanium alloy parts.
The unique combination of these elements in TC4 titanium alloy results in a series of remarkable properties. The alloy has a density of about 4.4 g/cm³, which is much lower than that of many traditional metal materials such as steel. This makes TC4 titanium alloy parts an ideal choice for applications where weight reduction is crucial. The α + β two - phase structure formed by the interaction of these elements endows the alloy with excellent comprehensive mechanical properties. It has high strength, good plasticity, and excellent fatigue resistance, enabling it to withstand complex stress conditions in various applications.
