Alticolor hard anodizing process

This is an electrolytic process carried out by immersing the titanium item into a solution whose temperature, movement and voltage is continually monitored. 

This type of anodising on titanium obtains an even layer with a typical intense grey colour that enables the component to acquire specific properties and characteristics.

Since 1996, Alticolor has been the trusted point of reference for companies in need of treatments on titanium components.

How we support our customers

A customer needed to increase the oxide thickness on some items to increase their biocompatibility. We worked together with Padua University's faculty of engineering, studying and finalising a new process that resulted in obtaining an oxide thickness of 10 micron, instead of the 5–6 micron produced with conventional methods.

Alticolor treatments undergo rigorous control procedures
resulting in certification to guarantee the quality
of the process management.

  • certificato-uni-en
  • certificato-uni-cei
  • certificato-qualanod
  • certificato-en-9100-2018
  • certificato-nadcap


The service providing assembly operations in cleanrooms is available for anyone requiring products to be assembled in a controlled environment, and is available for every sector either as a final step following treatment or as a one-off service.
