High-Performance Titanium Filler Wires:
At TSM TECHNOLOGY CO, we recognize that in the world of high-performance alloys, a weld is only as robust as the filler metal that feeds it. Our titanium welding filler wire is the result of decades of metallurgical expertise and advanced manufacturing processes. We utilize Vacuum Arc Remelting (VAR) and precision drawing to produce wires that exceed international standards like AWS A5.16 and ISO 24034.
Our Titanium Filler Wires are specifically designed to overcome the inherent challenges of titanium fabrication, such as interstitial contamination and surface oxidation. By maintaining ultra-low levels of Oxygen, Hydrogen, and Nitrogen, our products ensure that your welds maintain the same exceptional corrosion resistance and high strength-to-weight ratio as the base parent metal.

Product Range Overview
Our titanium TIG filler wire product line encompasses the most widely used grades in industrial applications:
Titanium Grade 2 Filler Wire (ERTi-2): Commercially pure titanium offering excellent corrosion resistance and superior weldability. Ideal for chemical processing, marine environments, and applications requiring optimal ductility.
Titanium Grade 5 Filler Wire (ERTi-5): Ti-6Al-4V alloy providing exceptional strength-to-weight ratio and elevated temperature performance. The preferred choice for aerospace structures, automotive components, and high-stress applications.
Specialty Grades: We also supply ERTi-1, ERTi-7, and ERTi-12 for specialized applications requiring specific corrosion resistance or mechanical properties.

Quality Control
Certified to AS9100 and ISO 9001 TSM Technology Co. operates a state-of-the-art manufacturing facility where every meter of wire is inspected for surface defects and dimensional accuracy. Our commitment to quality ensures that your high-value projects remain compliant with the strictest industry codes.

Industry Applications
Our titanium welding filler wire products serve critical applications across multiple high-performance industries where failure is not an option. Understanding these applications helps illustrate why quality, consistency, and reliability are non-negotiable in our manufacturing processes.

Aerospace
Grade 5 titanium filler wire is extensively used for welding airframe structures, landing gear components, and wing spars. The exceptional strength-to-weight ratio of Ti-6Al-4V allows for significant weight reduction while maintaining the structural integrity required for flight-critical applications. Modern commercial aircraft like the Boeing 787 and Airbus A350 contain over 15% titanium by weight.

Medical Device Manufacturing
Both Grade 2 and Grade 5 titanium welding filler wire are used for manufacturing orthopedic implants including hip replacements, knee joints, and bone plates. The excellent biocompatibility and osseointegration properties of titanium make it the material of choice for permanent implants.

Chemical Processing Industry
Process piping for chemical transport, particularly in chlor-alkali plants and pulp & paper mills, relies on titanium TIG filler wire for leak-free joints that maintain process purity and prevent contamination.
Why choose us?
Guaranteed Material Purity & Consistency
Every batch of our titanium filler wires undergoes comprehensive chemical composition analysis using ICP-OES spectrometers. We guarantee 99.2% minimum titanium purity for Grade 2 and precise Al-V ratios for Grade 5, eliminating concerns about material quality variations that could compromise weld integrity.
Complete Certification & Traceability
We provide EN 10204 3.1 Material Test Certificates with every shipment, documenting chemical composition, mechanical properties, and compliance with AWS A5.16 standards. Full batch traceability from raw material to finished product ensures accountability and regulatory compliance.
Comprehensive Size Range & Customization
From 0.8mm precision welding wire to 6.0mm heavy-duty filler rods, we offer the industry's most extensive size range. Custom diameters, lengths, and special packaging configurations are available to meet your specific production requirements.
