Using Titanium Alloys for CNC Machining

Titanium alloys offer excellent corrosion resistance compared to many alternative materials. Precise mixtures of alloys in different titanium grades and their high melting point and machinability allow producing titanium CNC machined parts with unique properties to suit every application. As the most biocompatible metal, titanium is used extensively in medical industries.

Coatings & Finishes

We provide a wide selection of aesthetic and functional coatings and finishes to meet any needs.

Finishes and Post-Processing Options

As-Machined: The most cost-effective and simple finish, As-Machined is the go-to choice for situations where a smooth surface won’t be exposed or its appearance isn’t of utmost importance.

Bead-Blasted: This creates a beautiful matte finish with a uniform texture. This approach is achieved by using abrasive media such as glass beads and aluminum oxide, producing a consistent finish.

Anodized: This method creates a robust oxide layer on the surface of the titanium that can also be colored in various shades. Ideal for outdoor applications, as the protective film safeguards against rust and corrosion!

Powder-Coated: Powder coating is an economical finishing process used on machined titanium parts to add a unique variety of colors, textures, and corrosion resistance. By melting and then curing the polymer-based powder onto the surface, it achieves a strong and durable finish.
