Titanium Extrusions: Precision Profiles for High-Performance Applications

1. What Are Titanium Extrusions?

Titanium extrusions are profiles made by forcing heated titanium through a die to create specific shapes. This process produces parts with consistent cross-sections and precise dimensions, making it ideal for complex designs that would be challenging or expensive to achieve with traditional machining or forging.

Extrusion is a highly efficient method for creating lightweight, strong, and corrosion-resistant components from titanium—critical qualities for industries like aerospace, medical, and energy.

How the Titanium Extrusion Process Works

Here’s how the extrusion process works:

1. Heating: Titanium billets are heated to a specific temperature to make them more workable.
2. Extruding: The heated billet is pushed through a custom die using high pressure, forming a continuous shape.
3. Finishing: The extruded profile is then straightened, cut to size, and finished according to specifications.

This method offers tight tolerance control while minimizing material waste—an important consideration when working with expensive materials like titanium.

Why Titanium Extrusions Are Different

Titanium extrusions are superior to other forms of titanium products for several reasons:

• Complex shapes: Extrusions allow for intricate cross-sectional designs in one step, which would require much more effort if made from flat plates or bars.
• Less machining: Because the material is shaped in one go, there’s less need for additional machining, saving both time and cost.
• Consistent properties: The extrusion process ensures uniform strengthalong the entire length of the profile.

Compared to forging, extrusions are ideal for creating long, continuous shapes with high-performance properties, while still being cost-effective.

Common Titanium Grades Used in Extrusion

Titanium extrusions are typically made from:

• Commercially Pure Titanium (Grade 1–4): Known for excellent corrosion resistance and good formability.
• Titanium Alloys (e.g., Ti-6Al-4V, Grade 5): Offers higher strength and better fatigue resistance for demanding applications.

The choice of grade depends on your project’s specific requirements, such as strength, corrosion resistance, and environmental conditions.
