Titanium Filler Rod

Titanium filler rods represent one of the most widely used titanium alloy products in advanced engineering applications. Among them, Ti-6Al-4V (Grade 5, "6-4") is the industry standard, combining high strength, excellent weldability, heat-treat capability, and superior fatigue resistance.

Designed for demanding environments, titanium filler rods are extensively used in precision welding processes, including:

• Plasma Arc Welding (PAW)

• Gas Tungsten Arc Welding (GTAW / TIG)

Their stable metallurgical performance ensures consistent weld quality, structural integrity, and long-term durability.
