Description of Titanium Wire(Straight Wire and Coil Wire)
Titanium, represented by the symbol Ti and atomic number 22, is a lustrous silver-gray metal known for its exceptional combination of high strength, low density, excellent corrosion resistance, and biocompatibility. These qualities render titanium essential in numerous sectors, particularly aerospace and medical applications. Titanium wire is available in various forms, including straight shape wire and coil/spool wire. Additionally, welding wire produced according to ASTM B861 standards ensures high quality and performance for welding applications, meeting the demands of various industries.
The metal is available in various grades, each designed for specific uses and categorized by its chemical composition and mechanical properties.
Grade 1: The softest and most ductile, with excellent corrosion resistance. It is used in chemical processing, marine applications, and medical devices.
Grade 2: The most widely used grade of titanium. It has a good balance of strength, ductility, and corrosion resistance. Commonly used in aircraft construction, chemical processing, and marine environments.
Grade 3: Stronger than Grade 2 but with slightly lower ductility. It is used in industrial and marine environments requiring higher strength.
Grade 4: The strongest of the commercially pure titanium grades. It is used in applications requiring higher strength, like aerospace components and medical implants.
Grade 5 (Ti-6Al-4V): The most commonly used titanium alloy. It contains 6% aluminum and 4% vanadium, offering high strength, good corrosion resistance, and good weldability. It is widely used in aerospace, medical implants, and high-performance engineering.
Grade 23 (Ti-6Al-4V ELI): Similar to Grade 5 but with lower levels of impurities (Extra Low Interstitial), making it more suitable for medical implants.
Grade 7: Similar to Grade 2 but with added palladium for enhanced corrosion resistance, particularly in chemical processing.

Titanium Wire manufacturing and treatment processes
Raw Material Preparation
- Titanium Sponge Production: Titanium ore is converted to titanium sponge through processes like the Kroll method, which reacts titanium tetrachloride (TiCl₄) with magnesium or sodium.
- Melting: The titanium sponge is melted in a vacuum arc remelting (VAR) furnace to produce titanium ingots.
Wire Drawing
- Billet Creation: The ingots are forged and rolled into billets or bars.
- Wire Drawing: The billets are then drawn through a series of dies to achieve the desired wire diameter. This process reduces the diameter while increasing the length, and multiple passes may be required to reach the final size.
Heat Treatment
- Annealing: The drawn wire is subjected to an annealing process to relieve internal stresses and improve ductility. This typically involves heating the wire to a specific temperature and then cooling it gradually.
Surface Treatment
- Cleaning: The wire is cleaned to remove any surface oxides or contaminants. This can involve pickling (using acid solutions) or other cleaning methods.
- Finishing: Depending on the application, the wire may undergo additional finishing processes such as polishing to achieve the desired surface smoothness.
Application
Aerospace: For structural components, fasteners, and engine parts, where high strength-to-weight ratios are critical.
Medical: In implants, surgical instruments, and dental applications, due to its biocompatibility and corrosion resistance.
Welding: As welding filler material, complying with standards like ASTM B861.
Chemical Processing: For equipment and piping where resistance to corrosive environments is essential.
