TITANIUM ETCHING

Titanium is often referred to as a "wonder metal," and for good reason. It boasts the strength of steel at nearly half the weight, survives the most corrosive environments on Earth, and is completely biocompatible with the human body.

​

However, these same legendary properties—its toughness and poor heat conductivity—make it a nightmare for traditional machining. At Metching, our advanced titanium etching services provide a solution that traditional tools simply cannot match, delivering high-precision components with zero material compromise.

Why Conventional Machining Struggles with Titanium

 

If you’ve ever tried to cut titanium with a standard CNC mill or a laser, you’ve likely encountered the "Titanium Challenge":

​

• Heat & Tool Wear: Titanium is a poor conductor of heat. During traditional cutting, heat stays trapped at the point of contact, quickly destroying expensive drill bits and cutting tools.

• Material Distortion: Because titanium is strong yet elastic, mechanical forces like stamping or waterjet cutting can cause the part to spring back or warp, ruining tight tolerances.

• Surface Contamination: At high temperatures, titanium becomes highly reactive, leading to "alpha-case" (a brittle surface layer) or burrs that require costly manual cleaning.

 

The Chemical Etching Advantage

 

Chemical etching (also known as Photochemical Machining) sidesteps these physical hurdles entirely. By using specialized acid solutions to selectively dissolve metal, we treat the titanium with a "cold" process that preserves its natural excellence.

​

Key Benefits of Etched Titanium:

​

• Zero Heat-Affected Zones: Since no heat is used, there is no risk of thermal expansion, warping, or changes to the metal's internal grain structure.

• Complex Geometries for Free: Unlike CNC machining, where more complexity means more cost, etching can produce incredibly intricate patterns and meshes simultaneously at no extra charge.

• Perfectly Bur-Free: Parts come out of the process with smooth, clean edges, eliminating the need for secondary finishing.

• Precision and Scalability: We achieve tolerances as tight as ±0.01mm, making it possible to produce thousands of identical, micro-sized parts with absolute consistency.

Titanium Grades We Support

 

Whether you need commercially pure titanium for its ductility or high-performance alloys for extreme environments, our etching process is optimized for all major grades:

 

• Grade 1 & 2: Commercially pure, highly ductile  >>>  Chemical tanks, heat exchangers, marine parts

• Grade 5 (Ti-6Al-4V): The "Workhorse" alloy; extreme strength  >>>  Aerospace frames, engine parts, high-end racing

• Grade 23 (ELI): Extra-low impurities, biocompatible  >>>  Medical implants, orthopedic devices, surgical tools

• Nitinol: Shape-memory nickel-titanium alloy  >>>  Stents, orthodontic wires, flexible medical components

​

Engineering the Future: Industry Applications

 

Titanium’s unique profile makes it the preferred choice for mission-critical applications where failure is not an option.

​

• Aerospace & Defense: We produce lightweight wing skins, engine turbine blades, and heat exchangers that can withstand the rigors of flight.

• Medical & Dental: Etching is used for orthopedic implants, dental prosthetics, and surgical meshes. The process can even be tuned to create specific surface roughness that helps bone fuse directly to the implant (osseointegration).

• Energy & Automotive: From bipolar plates for hydrogen fuel cells to high-performance racing components that shed every unnecessary gram of weight.
