Titanium Wire Types, Grades, Applications and Manufacturing Specifications

Titanium Wire Overview

Titanium wire is a high-performance material widely used in industrial and consumer applications.

It is known for its excellent strength-to-weight ratio, corrosion resistance, and biocompatibility.

This makes it suitable for aerospace, medical, welding, and jewelry industries.

Titanium wire is produced through cold drawing processes to achieve precise diameters.

It is the finest form of titanium product used in manufacturing and fabrication.

Due to its low weight and high strength, it performs well under extreme mechanical stress.

Types of Titanium Wire

Titanium wire is available in several forms depending on application and processing requirements.

Spools

Spools are typically used for diameters under 3.0 mm.

They are commonly supplied in 1 lb, 5 lb, or 25 lb reels.

Coils

Coils are used in industrial manufacturing and spring production.

They are supplied in large loose loops for continuous processing.

Straight Lengths

Straight lengths are typically 36 inches or 1 meter long.

They are mainly used for TIG welding and medical applications.

1. Common Grades & Specifications

Titanium wire grades are selected based on structural or filler requirements.

2. Available Product Forms & Dimensions

Titanium wire is supplied in coils, spools, or straightened cut lengths depending on usage.

It is widely used in precision welding and manufacturing industries.

3. Surface & Tolerance Conditions

The surface condition of titanium wire directly affects its performance.

Pickled: Acid cleaned surface with matte silver appearance.

Bright: Diamond-drawn surface with high gloss finish.

Black: Industrial surface with lubricant or oxide layer.

Chemically Cleaned: Used for welding applications to avoid contamination.

Tolerance levels typically range from ±0.02 mm to ±0.05 mm depending on diameter.

1. "Can I use Grade 2 wire to weld Grade 5 plate?"

The Answer: Generally, no. You should match the filler wire to the base metal. Using Grade 2 wire on a Grade 5 plate will result in a weld that is much weaker than the surrounding material, leading to joint failure.

2. "Why is my titanium wire snapping during bending?"

The Answer: This is usually due to hydrogen embrittlement or work-hardening. If the wire was drawn too many times without vacuum annealing, it becomes brittle. Ensure you are ordering "Annealed" (Condition A) wire for any application involving tight bends.

3. "How do I achieve different colors on the wire?"

The Answer: Titanium wire is unique because it can be anodized. By submerged the wire in an electrolyte bath and applying specific voltages, you grow a transparent oxide layer. The thickness of this layer refracts light into different colors (e.g., 25V for Blue, 60V for Yellow).

4. "Is the wire 'Spring Tempered'?"

The Answer: If you are making springs or eyeglass frames, you need Cold Worked wire. If you need to weave a mesh, you need Annealed wire. Always specify the "Temper" to ensure it has the right "spring-back" for your project.

5. "What is the spooling standard?"

The Answer: For automated welding or 3D printing (DED), we use standard SD300 or BS300 spools to ensure compatibility with wire feeders. For fine jewelry wire, smaller plastic spools are standard.
