Overview

Titanium (CAS 7440-32-6) is a transition metal element with exceptional corrosion resistance and high strength-to-weight ratio properties. This versatile metallic element stands as one of the most important materials in modern industrial applications, combining remarkable mechanical properties with outstanding chemical stability. Titanium exhibits excellent resistance to corrosion in various environments, including seawater, acids, and alkalis, making it invaluable across multiple sectors. With its atomic number 22 and molecular weight of 47.867 g/mol, titanium demonstrates unique characteristics that distinguish it from other structural metals. The metal's exceptional strength-to-weight ratio surpasses that of steel while maintaining significantly lower density, approximately 60% lighter than steel with comparable strength properties. Titanium's melting point reaches 1668°C, contributing to its thermal stability in demanding applications. From a safety perspective, metallic titanium presents minimal hazards under normal handling conditions, though fine titanium powder can pose fire risks and is classified under ADR Class 4.2 for transport purposes. Industrial applications span aerospace manufacturing, where titanium components are essential for aircraft engines and structural elements, chemical processing equipment due to its corrosion resistance, and medical implants leveraging its biocompatibility. The automotive industry increasingly utilizes titanium for high-performance components, while the marine sector values its seawater resistance properties. Unlike organometallic compounds such as tris(2-methylpropyl)alumane or trioctylalumane used in specialized chemical processes, titanium serves primarily as a structural and functional metal. OYSI provides reliable access to high-quality titanium products for European industrial customers, supporting diverse applications across multiple sectors with comprehensive technical documentation and regulatory compliance.

Frequently Asked Questions

What is titanium?

Titanium is a chemical element with the symbol Ti and CAS number 7440-32-6, belonging to the transition metals group. It has a molecular weight of 47.867 g/mol and is characterized by its exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility. This silvery-white metallic element is known for its durability and ability to withstand extreme temperatures, making it highly valued in various industrial applications.

What are the physicochemical properties of titanium?

Titanium is a lustrous, silvery-white solid metal at room temperature with excellent corrosion resistance properties. It has a high melting point of approximately 1,668°C and a density of 4.5 g/cm³, making it significantly lighter than steel while maintaining comparable strength. Titanium is insoluble in water and most organic solvents but can be dissolved in concentrated acids like hydrofluoric acid.

What is titanium used for?

Titanium is extensively used in aerospace applications for aircraft components, engine parts, and structural elements due to its lightweight and high-strength properties. It serves critical roles in medical implants, chemical processing equipment, marine applications, and architectural structures. The automotive industry increasingly utilizes titanium for high-performance components, while the chemical industry values it for corrosion-resistant equipment and piping systems.

How to handle titanium safely?

Titanium handling requires standard metalworking safety precautions including wearing appropriate personal protective equipment such as safety glasses, gloves, and protective clothing. When machining or grinding titanium, ensure adequate ventilation to prevent inhalation of metal particles and use appropriate dust collection systems. Fire prevention measures are crucial as titanium powder and fine particles can be pyrophoric, requiring careful handling away from ignition sources.

How to store titanium correctly?

Titanium should be stored in a dry, well-ventilated area away from incompatible materials and ignition sources. Keep titanium products in their original packaging or suitable containers to prevent contamination and physical damage. As classified under ADR Class 4.2 Group I, special attention must be paid to preventing spontaneous combustion, particularly for powdered forms, by maintaining proper storage temperatures and avoiding contact with oxidizing agents.

What to do in case of contact with titanium?

Titanium contact typically poses minimal immediate health risks due to its biocompatible nature and lack of specific hazard classification. In case of skin contact with titanium particles, wash the affected area with soap and water. If titanium dust gets in eyes, rinse thoroughly with clean water for several minutes. For inhalation of titanium particles, move to fresh air immediately and seek medical attention if respiratory irritation occurs.

How to dispose of titanium appropriately?

Titanium disposal should follow local and national waste management regulations, treating it as recyclable metal waste when possible. Due to its high value and recyclability, titanium scrap is typically collected by specialized metal recycling facilities rather than disposed of as general waste. Contaminated titanium materials may require special handling procedures depending on the nature of contamination, and should be managed according to applicable environmental regulations.

How to transport titanium?

Titanium is classified under ADR Class 4.2, Group I, indicating it may be subject to spontaneous combustion regulations during transport. This classification primarily applies to titanium powder and fine particles, which require special packaging and labeling according to dangerous goods transport regulations. Solid titanium forms typically have fewer transport restrictions, but proper documentation and packaging according to ADR requirements must be maintained for commercial shipments.

Is titanium subject to specific regulations?

Titanium is not classified as a Substance of Very High Concern (SVHC) under REACH regulation and has no specific GHS hazard classification or signal words. However, it remains subject to standard REACH registration requirements for chemical substances in the European Union. Specific applications may be subject to additional sector-specific regulations, particularly in aerospace, medical device manufacturing, and food contact applications where material specifications and certifications are required.

Where to buy titanium in Europe?

Titanium is available through OYSI, a European distributor of chemical products, offering reliable supply chains across European markets. As a specialized chemical distributor, OYSI can provide various grades and forms of titanium suitable for different industrial applications. Their European presence ensures compliance with local regulations and efficient delivery to customers requiring this high-performance metal for their manufacturing and processing needs.
