praxair gases for consistent atmospheres in Sintering

Stronger metals, better parts

Sintering Sintering is a process that uses compressed metal or ceramic powders to form various shapes. These structural parts are usually complex. Almost all metals can be sintered, but pure metals with little to no surface contamination result in a better product. The process of sintering with atmospheric pressure requires a protective gas such as hydrogen, nitrogen, or carbon monoxide. Using nitrogen and hydrogen-based atmospheres results in a more consistent performance for your sintering operation. Our atmospheres that use hydrogen or carbon monoxide are considered reducing agents. They work together and protect the sintered parts from oxidation and decarburization.

Benefits of sintering: 

  • Reproducible size and hardness

  • Brighter and cleaner parts

  • Decreased soot formation and oxidation

  • Fewer process interruptions

  • Decreased idle furnace time

  • Faster start-ups
