GR2 titanium wire

Gr2 low strength, good plasticity, good low temperature toughness, corrosion resistance is very high. Has good pressure machining process performance, cutting performance is poor. Heating in nitrogen can be burned, so titanium in the heating and welding should be protected by argon.

What is GR2 Titanium Wire

Titanium wire is highly valued for its excellent combination of high strength, low weight, corrosion resistance, and biocompatibility. It offers superior quality and performance thanks to its precise composition and strict manufacturing standards.

GR2 titanium wire contains nominally 2% molybdenum and 6% aluminum alloyed with titanium. The molybdenum increases strength and creep resistance at elevated temperatures, while the aluminum stabilizes the alpha phase crystal structure to ensure excellent cold formability and mechanical properties. The remainder is high purity titanium.

With its optimized alloy composition, It provides an outstanding balance of properties:

  • High strength-to-weight ratio

  • Excellent corrosion resistance

  • Low thermal expansion

  • Non-magnetic

  • Exceptional cold formability

  • Good ductility and toughness

  • Excellent biocompatibility

These characteristics make GR2 an ideal choice for applications where strength, low weight, and corrosion resistance are critical, including aerospace, automotive, medical devices, chemical processing, and more.

Product Specifications

It is available in a wide range of sizes and strengths to suit specific application requirements. Standard wire diameters range from 0.010” to 0.500” (0.25mm to 12.7mm) with tensile strengths from 100 ksi to 300 ksi (690 MPa to 2070 MPa). Custom diameters and properties can also be supplied.

It meets the exacting quality standards of AMS 4928 and AMS 4967. Wire is supplied in continuous coil lengths up to 5000 lbs, precision spooled to ensure uniform unwinding and prevent tangling.

Composition

It has the following nominal composition:

  • Titanium: 90%

  • Aluminum: 6%

  • Molybdenum: 2%

  • Oxygen: 0.08%

  • Iron: 0.30%

  • Carbon: 0.10%

  • Nitrogen: 0.05%

The remainder consists of trace amounts of hydrogen and other impurities. Tight controls during melting, alloying, and processing ensure the chemical composition stays within specified limits to guarantee mechanical properties and corrosion resistance.

Mechanical Properties

It offers an excellent combination of tensile properties, making it stronger than commercially pure titanium while maintaining good formability:

  • Tensile strength: 125-300 ksi (862-2070 MPa)

  • Yield strength: 115-290 ksi (793-2000 MPa)

  • Elongation at break: 10-25%

  • Reduction of area: 25-55%

In addition to high strength, GR2 titanium demonstrates:

  • Outstanding corrosion resistance

  • Low modulus of elasticity

  • Excellent fatigue strength

  • Good impact toughness

  • Non-magnetic permeability

These properties make GR2 suitable for the most demanding applications across multiple industries.

Applications of GR2 Titanium Wire

With its optimized balance of mechanical, chemical, and physical properties, It serves critical applications across diverse industries:

Aerospace - Hydraulic tubing, fasteners, engine components, landing gear Automotive - Valves, springs, fasteners, tubing Medical - Implants, prosthetics, instruments, braces Chemical - Heat exchangers, condensers, tubing, pipe Power Generation - Condensers, tubing, heat exchangers
Oil & Gas - Valves, wellhead components, completion equipment

GR2 is also widely used in sports equipment, marine hardware, food processing equipment, and more. Its biocompatibility and corrosion resistance make it an ideal choice for products that must perform safely in prolonged contact with the human body.

Frequently Asked Questions

Q: What is the difference between ASTM B863 Gr2 titanium wire and other titanium alloys?

A: GR2 has a higher aluminum content than GR1 for increased strength. It offers better corrosion resistance than titanium 6-4 due to lower molybdenum and vanadium content.

Q: What types of certifications are available?

A: linHui provides full material traceability and certifications including mill test reports, composition analysis, tension test results, NDT inspection, etc.

Q: Can it be welded?

A: Yes, GR2 can be readily welded using inert gas shielding. Welding maintains the excellent corrosion resistance of the base metal.

Q: What are the typical applications?

A: Key applications include aerospace components, valves, medical implants, chemical processing equipment, and marine hardware.

Q: Does linHui stock inventory?

A: As a manufacturer, we maintain extensive inventory of standard and custom sizes to enable rapid delivery. Contact us for availability.
