18 Gauge Titanium Wire, 1.02 mm Gr2 and Gr5 for Jewelry and Industrial Use

Shaanxi Chuanghui Daye Metal Material Co., Ltd. supplies titanium wire for jewelry work. Industrial buyers use it too. One listed size is 18 gauge titanium wire. Nominal diameter is 1.02 mm. Buyers can choose Ti Gr2 or Gr5. The listing gives tensile strength as 345–895 MPa. Elongation comes in at 10–25%. Density is 4.43–4.51 g/cm³. That balance lets the wire be formed and coiled. Weaving works as well. Parts made from it stay light. TIG welding suits it. So do chainmaille weaving, coiling, and anodizing. The company is based in Baoji High-tech Development Zone. People call that area China's Titanium Capital.

What Is wire?

18 gauge measures about 1.024 mm (0.0403 in) in the American Wire Gauge system. That size makes the product stiff enough for light structural parts. Cold forming still works. Weaving does too, since the wire stays ductile. For titanium wire, ASTM B863 is a common reference. Before you order, check the standard your project needs.

Specifications

Both Gr2 and Gr5 are covered by the tensile strength and elongation ranges. You will not find values for a specific grade and temper here. No temper is specified. Supply form is not stated. It could be coil, spool, or cut length. Surface finish is missing too. Nothing is said about the applicable standard. The listing also leaves out MOQ and lead time. Email the company before you order to confirm these details.

Key Properties

Strength and weight. Titanium gives you good strength without much weight. That matters when a finished part has to stay light.

Springback. The modulus sits near 110 GPa. Steel is about twice that. Coil or bend titanium and the springback will be clear.

Corrosion behavior. Titanium grows a thin oxide skin on its surface. Saltwater and chlorine find it harder to get past that skin. Does a certain setup hold up? Your chemistry, your temperature, and exposure time still decide that. Test it under your own conditions.

Heat and finishing. The melting point sits near 1,668 °C. That lets the wire take far hotter conditions than aluminum ever could. It has no magnetic pull either. Want color? Anodizing gives you that, and no dyes are needed.

Skin contact. Jewelry worn against the body uses titanium a lot. Does your product need a particular biocompatibility certification? Then check the grade and the paperwork before you order.

Choosing Between Gr2 and Gr5

Gr2 means commercially pure titanium. This one bends by hand with less effort, since it is softer. Weaving and jump rings suit it well, and so does everyday bending work.

Ti-6Al-4V is what Gr5 stands for. Stiffer and harder, it fits parts that have to hold up against deformation.

Temper matters as well. Annealed wire is softer and bends more easily. Wire with a harder temper holds its shape for longer. Check the 345 to 895 MPa strength range and the 10 to 25% elongation range against what your forming step needs. Ask which grade and temper your order can get after that.

Applications

Welding. TIG welding titanium parts? 18 gauge titanium wire can work as a filler rod. A fine diameter makes the weld pool easier to control. Shield the weld with argon. That stops oxidation.

Industrial assemblies. Wire this size also turns up in woven mesh, hangers, and small frameworks that sit in corrosive conditions. Check first that it holds up against your own chemistry and temperature before you write it into a spec.

Jewelry and chainmaille. Jump rings, chainmaille, and frameworks are common uses for this product in jewelry. Its strength helps weaves hold their shape. Daily wear stays comfortable as well, because the density is low.

Incoming Batch Checklist for 18 gauge titanium wire

• Grade: Gr2 and Gr5 look the same. Get a material test report (MTR) or XRF testing to confirm which grade you have.
• Diameter: Take readings at a few points. Compare each one to the 1.02 mm nominal value. Also compare them to the tolerance both sides agreed on.
• Surface: Look for residue from drawing lubricant. Seams count too, and so do deep scratches. Each of these can concentrate stress.
• Mechanical results: Compare tensile strength and elongation with the temper your job calls for.

Be used in a wide range of industries.

FAQ

Q: Will regular wire cutters work on this wire?

A: Most of the time, no. Reliable steel nippers can get through softer grades. Gr5 and work-hardened wire are a different story. They can damage regular jewelry cutters. Go with flush cutters that have tungsten carbide inserts. Heavy-duty shears are another option.

Q: Why does it spring back more than copper or silver?

A: Titanium has a lower modulus of elasticity. Bend the wire slightly past the angle you want. That takes care of the recoil. For coils, choose a mandrel a little smaller than the inner diameter you're after.

Q: Can I solder it?

A: Most of the time, traditional soldering won't work. Titanium builds up a stable oxide layer. The usual alternatives are laser welding, pulse arc welding, or vacuum brazing under inert gas.

Q: How do I tell Gr2 from Gr5?

A: To the eye, they are the same. Gr5 is stiffer, and bending it by hand takes more effort. Still, telling them apart for sure calls for an MTR or an XRF test.

Q: Can the wire be anodized?

A: Yes. Color comes out of anodizing with no dyes at all. Which color you get depends on the voltage. So try a scrap piece first, and clean the surface before you start.

Q: Which specifications are listed?

A: This product is 1.02 mm in diameter, in Ti Gr2 or Gr5, with tensile strength of 345–895 MPa. See the Product Specifications table for all values.
