Metal Finishing Techniques & Processes
Since the earliest days of metal usage thousands of years ago, people have needed to manage and adjust the characteristics of their metal creations.
In modern times we employ a number of metal finishing techniques and technologies that continue this age-old endeavor.
Benefits of Metal Finishing
Although metal finishing is a simple idea, it is one that can accomplish many goals, including:
- preventing corrosion
- changing conductibility
- altering emissivity
- enhancing or reducing conductivity
- modifying lubricity
- improving wear
- increasing hardness
- improving heat response & resistance
- enhancing aesthetic appearance
From its humble beginnings with our ancestors to the advanced techniques we employ today, metal finishing is part of our unending collective effort to improve the performance of the tools we build and the beauty of the things we create.
