Introduction

Titanium is a high-performance metal that began industrial production in the early 1950s. With abundant reserves and outstanding properties, titanium ranks just behind iron and aluminum in industrial importance, earning the title of the “rising third metal.” Titanium and titanium alloys are widely recognized for their low density, high specific strength, excellent corrosion resistance, low thermal expansion, low thermal conductivity, non-magnetic behavior, and excellent biocompatibility. Additionally, titanium materials demonstrate unique functionalities, including hydrogen storage, superconductivity, shape memory, superelasticity, and high damping, making them ideal for advanced functional titanium alloys, titanium sheets, titanium bars, and titanium pipes.

Among these properties, the two most notable advantages of titanium and corrosion resistant titanium alloys are their high specific strength and superior corrosion resistance. These features allow titanium materials to be widely applied in aerospace titanium components, medical titanium implants, corrosion resistant titanium piping, naval vessels, marine engineering, nuclear power plants, thermal power plants, chemical and petrochemical equipment, and metallurgical applications. As a result, titanium and titanium alloys serve not only as lightweight, corrosion-resistant structural materials but also as functional titanium materials, biomedical titanium alloys, and aerospace titanium components in modern high-end industries.

Atomic and Crystal Structure of Titanium

Titanium (Ti) has an atomic number of 22 and a relative atomic mass of 47.867. Its naturally occurring isotopes include Ti-46, Ti-47, Ti-48, Ti-49, and Ti-50, which contribute to its stable physical and chemical properties. Pure titanium exhibits a high melting point ranging from 1640°C to 1670°C, making it suitable for high-temperature applications. These intrinsic atomic characteristics form the foundation for the excellent mechanical strength, corrosion resistance, and biocompatibility seen in titanium, titanium alloys, aerospace titanium, and medical titanium materials.

Electrical Properties of Titanium

As a transition metal, titanium (Ti) exhibits relatively high electrical resistivity. Its electrical conductivity is significantly influenced by impurities such as oxygen, nitrogen, carbon, and iron, which can cause variations in measured resistivity. Despite this, studies have shown that titanium demonstrates superconductivity when cooled close to absolute zero. These unique electrical properties contribute to the versatility of titanium and titanium alloys, making them suitable for specialized applications in aerospace titanium components, corrosion resistant titanium materials, and high-performance titanium devices.

Thermal Properties of Titanium

Titanium (Ti) and titanium alloys exhibit low coefficients of thermal expansion and low specific heat capacity. Their thermal conductivity is relatively low, approximately 1/15 of aluminum and about 1/5 of steel, which influences heat transfer in high-performance applications. These thermal characteristics make titanium, corrosion resistant titanium, and aerospace titanium materials ideal for lightweight structural components, heat exchangers, and high-temperature industrial equipment where dimensional stability and thermal resistance are critical.

Chemical and Corrosion Properties of Titanium

Titanium (Ti) and titanium alloys exhibit high chemical reactivity, which increases significantly with rising temperature. At room temperature, the reactive surface of titanium begins to absorb hydrogen, and hydrogen uptake increases notably around 300°C. Titanium reacts with hydrogen significantly at approximately 600°C, while reactions with nitrogen occur above 700°C. Vacuum annealing can nearly completely remove hydrogen, but oxygen and nitrogen cannot be fully eliminated.

Despite its chemical reactivity, titanium and titanium alloys demonstrate outstanding corrosion resistance in most chemical media, making them highly suitable for corrosion resistant titanium materials, titanium piping, and aerospace titanium components. However, four inorganic acids, four concentrated hot organic acids, and highly corrosive aluminum chloride can cause severe corrosion. At elevated temperatures, titanium and titanium alloys are also sensitive to stress corrosion in dry sodium chloride environments.

In most galvanic systems, titanium and titanium alloys exhibit high positive electrochemical potentials, second only to nickel-based alloys. This property ensures that when in contact with other metals, titanium remains largely immune to galvanic corrosion, offering excellent electrochemical corrosion resistance. These characteristics make titanium, corrosion resistant titanium, and aerospace titanium materials ideal for demanding industrial, chemical, and marine applications.

Mechanical Performance of Titanium

The mechanical performance of titanium and high-strength titanium alloys is strongly influenced by the presence of impurities. Increasing levels of oxygen, nitrogen, and carbon can enhance tensile strength but reduce ductility. Among these, nitrogen has the most significant impact on reducing plasticity, oxygen has a moderate effect, and carbon has the least influence.

Careful control of these impurities is essential for producing aerospace structural titanium, medical-grade titanium alloys, and corrosion-resistant titanium alloys that require a precise balance between strength, flexibility, and long-term durability. Understanding the relationship between impurity content and mechanical properties is critical when selecting titanium materials for critical industrial, aerospace, or biomedical applications.

Common Classifications, Grades, and Characteristics of Titanium and Titanium Alloys

Titanium materials are widely used in manufacturing critical components and equipment that operate under extreme conditions. Common titanium products include titanium sheets, titanium pipes, titanium bars, titanium wires, titanium forgings, and titanium castings. These products are essential in industries requiring high-performance titanium alloys for aerospace, medical, chemical, and marine applications.

Titanium and titanium alloys are primarily classified into three types based on crystal structure:

1. Alpha (α) Titanium – Exhibits excellent corrosion resistance, good weldability, and high creep strength, making it suitable for chemical processing equipment, aerospace components, and biomedical implants.

2. Beta (β) Titanium – Offers high strength and formability at elevated temperatures, often used in aerospace structural parts, high-strength fasteners, and industrial machinery components.

3. Alpha-Beta (α+β) Titanium – Combines the corrosion resistance of α-phase with the strength of β-phase. Alloys such as Ti-6Al-4V (Grade 5) are widely used in aerospace, medical devices, and high-performance industrial applications.

Understanding the classification and characteristics of different titanium alloys helps engineers and designers select the appropriate titanium materials for applications requiring lightweight, corrosion-resistant, and high-strength properties.
