ASTM Grade 5 Gr2 Polished Titanium Wire For Making Jewelry

ASTM Grade 5 Gr2 Polished Titanium Wire For Making Jewelry

Precision-manufactured ASTM Grade 5 Gr2 Polished Titanium Wire For Making Jewelry,made from the Ti-3Al8V6Cr4Mo4Cr alloy composition, is available from LINHUI Titanium. With diameter options ranging from φ0.8mm to φ6.5mm, our wire has a remarkable tensile strength of ≥700 MPa, which is 30% more than standard standards. A minimum of 75% titanium purity and stringent tolerance control within ±0.02mm are guaranteed for every batch. Micro-defects are eliminated by the mirror-polished surface finish, guaranteeing consistent workability for complex jewelry designs. We provide factory-direct quality, supported by ISO 9001:2015 and EN 10204 3.1 certification, with more than 200 tons of stock inventories and FDA-compliant material traceability. We can accelerate trial orders up to 50 kg in 3–7 days.

Key Features & Benefits 

Improved Strength to Weight Ratio

Our polished titanium wire is ideal for comfortable yet durable jewelry because it is 40% lighter than steel and has a tensile strength of over 700 MPa.

Hypoallergenic and biocompatible

Its proven biocompatibility eliminates skin irritation, making it perfect for clients with sensitive skin and medical-grade body jewelry applications.

Excellent Corrosion Resistance

The natural oxide coating is resistant to tarnishing and discoloration from chlorine, ocean, and daily wear even after decades of use.

Precise Surface Quality

Multi-stage polishing is used to achieve Ra 0.2μm surface roughness, which produces a lovely sheen and clean edges that stop thread fraying during wire-wrapping.​​​​​​​

Product Information For ASTM Grade 5 Gr2 Polished Titanium Wire For Making Jewelry

Manufacturing Process

Vacuum Arc Remelting (VAR) is the first stage.

For constant mechanical qualities, the triple-melt technique removes impurities and guarantees uniform alloy distribution.

Stage 2: Cold Drawing and Hot Extrusion

Precise diameter tolerance and increased surface density are achieved by controlled cold rolling. The ideal ductility for jewelry making is maintained over several annealing cycles.

Step 3: Polishing in Multiple Stages

Microscratches are eliminated by progressive buffing with diamond compound, which is followed by electrolytic polishing for a mirror-quality finish.

Step 4: Last Inspection

Before spooling in a cleanroom setting, subsurface flaws are found using 100% laser diameter scanning and eddy current testing.

Quality Inspection

· Dimensional Verification: Laser micrometer inspection ensures h8 tolerance compliance

· Tensile Testing: ASTM E8 protocol validates strength and elongation per batch

· Surface Analysis: Microscopic examination confirms defect-free polished finish

· Chemical Analysis: ICP-OES testing verifies alloy composition and interstitial limits

· NDT Testing: Eddy current detection eliminates wires with internal cracks or laps

· Traceability: Each spool tagged with heat number and EN 10204 3.1 certificate

Applications

Manufacturing of Fine Jewelry

Sculpted artwork, wire wrapping, and chain-making all call for lightweight, high-strength materials with a lasting sheen.

Jewelry with body piercings

Surgical-grade body jewelry, nose rings, and earring posts all benefit from corrosion resistance and biocompatibility.

Medical Device Components

Orthodontic archwires and maxillofacial reconstruction cables demanding non-magnetic properties and tissue compatibility.

Luxury Watch Components

Spring bars, bracelet pins requiring durability without adding weight to premium timepieces.

Craft & Artisan Projects

Sculptural wire art and decorative metalwork where material integrity ensures lasting craftsmanship.

FAQ

Q: Is it possible to anodize this wire to make colored jewelry?

A: Anodic oxidation is perfectly accepted by the polished surface. Without compromising strength, voltage control creates consistent rainbow, blue, gold, and purple colors.

Q: What distinguishes Grade 5 wire from Grade 2 wire?

A: While our Ti-3Al8V6Cr4Mo4Cr delivers intermediate performance perfect for jewelry requiring both formability and durability, Grade 5 (Ti-6Al-4V) gives 50% greater strength than Gr2.

Q: After bending, is heat treatment necessary for the wire?

A: No. There is enough ductility for cold-forming in the annealed state. For intricate spring designs, stress-relief annealing at 480°C may be used.

Q: What impact does surface finish have on the longevity of jewelry?

A: Surface microcracks that cause fatigue failure are eliminated by mirror polishing. By avoiding stress concentration locations, our Ra 0.2μm finish prolongs the life of jewelry.

Q: Is laser welding appropriate for this wire?

A: Definitely. When combining complex jewelry components with argon shielding, a clean polished surface guarantees contamination-free weld pools.---
