Seamless Titanium Tube Grade 4
The fourth - grade titanium alloy has main alloying elements such as aluminum, chromium, and molybdenum added to it. As a result, its strength, toughness, and corrosion resistance have been notably enhanced. This alloy is chiefly applied in the structural components of aeroengines, like the combustion chamber top covers, ducts, and turbine blades.
Description
Grade 4 titanium is an exceptional material renowned for its outstanding characteristics.
Chemical Composition:
Grade 4 titanium predominantly consists of a substantial proportion of titanium, usually exceeding 99%. Stringent control is exerted over impurity elements including iron, carbon, nitrogen, hydrogen, and oxygen, confining them within specific thresholds. This meticulous regulation is essential for maintaining the material's superior quality and performance.
Physical Properties:
- Low Density: Distinguished by its relatively low density when juxtaposed with numerous other metals, Grade 4 titanium is both lightweight and robust.
- High Melting Point: Boasting a high melting point of approximately 1660°C, it is capable of withstanding elevated temperatures without experiencing substantial deformation.
- Good Conductivity: It exhibits moderate levels of electrical and thermal conductivity.
Mechanical Properties:
- Strength: Grade 4 titanium surpasses some lower-grade titanium variants in terms of strength. Its tensile strength can attain a remarkable magnitude, rendering it an ideal choice for applications where strength is of utmost importance.
- Toughness and Ductility: It displays excellent toughness and ductility, enabling it to be bent and shaped without the propensity to crack easily.
- Fatigue Resistance: This grade of titanium showcases remarkable fatigue resistance, allowing it to endure repeated loading cycles without succumbing to failure.
First-class titanium production technology

Corrosion Resistance:
Grade 4 titanium showcases remarkable corrosion resistance across a diverse array of environments. It exhibits exceptional resilience against acids, alkalis, and saltwater. This extraordinary ability to resist corrosion makes it a prime candidate for deployment in harsh chemical settings and marine environments, where exposure to corrosive substances is prevalent.
Applications:
- Aerospace Industry: In the aerospace sector, Grade 4 titanium plays a pivotal role in the fabrication of various aircraft components. It is employed in the production of engine parts, which need to endure high temperatures and mechanical stresses. Additionally, it is used for structural elements that contribute to the aircraft's strength and integrity, as well as for fasteners that ensure the secure assembly of different parts.
- Medical Field: Thanks to its biocompatible nature, which allows it to interact harmoniously with the human body, and its excellent corrosion resistance, Grade 4 titanium finds extensive application in the medical field. It is utilized in the manufacturing of medical implants, such as hip and knee replacements, which need to last for long periods within the body without causing adverse reactions. Moreover, it is used for surgical instruments, where its durability and resistance to corrosion are highly valued.
- Chemical Industry: Given its robust resistance to chemical corrosion, Grade 4 titanium is eminently suitable for use in chemical processing equipment. It can be used to construct reactors, tanks, and other vessels that come into contact with a wide variety of chemicals. Additionally, it is employed for pipelines, ensuring the safe and efficient transportation of chemical substances.
- Marine Engineering: In marine engineering, Grade 4 titanium is highly prized for its ability to withstand the corrosive effects of seawater. It is used in the construction of marine structures, such as offshore platforms, which are constantly exposed to the harsh marine environment. Additionally, it is used for marine equipment, including propellers and fittings, where its corrosion resistance helps to extend the lifespan of the components.
