TA1G (ERTi-1) Commercially Pure Titanium Welding Wire

TA1G is a Chinese grade of commercially pure titanium in welding-wire form, corresponding to AWS A5.16 ERTi-1 / ASTM Grade 1. It shares the same composition and properties as TA1, but is supplied as straight length or coil wire for TIG/MIG welding and fastener manufacture, offering excellent ductility, corrosion resistance and biocompatibility.

Overview

• Material: TA1G — CP titanium welding wire / fastener stock
• International equivalent: AWS A5.16 ERTi-1 / ASTM Gr.1 / UNS R50240
• Typical forms: straight wire and coiled wire (for TIG/MIG); bar and coil for fasteners

Mechanical Properties

Key Features

• Low density, moderate strength and excellent formability;
• Good corrosion resistance against a wide range of media;
• Good biocompatibility;
• Stable properties at low temperature.

Fabrication & Heat Treatment

• Hot working: forged or rolled at 700–900 °C; protect the surface during heating.
• Cold working: cold drawn and rolled; intermediate annealing is required at high cold-reduction levels.
• Welding: typically TIG welding; clean the surface thoroughly before welding.
• Annealing: 550–700 °C for 1–2 h.

Typical Applications

• Aerospace: rivets and other fasteners;
• Chemical industry: corrosion-resistant components;
• Food and medical equipment: food-processing equipment and surgical instruments;
• Welding consumable: filler wire (ERTi-1) for CP titanium fabrication.
