This material is not chemically treated to protect against oxidation. However, the product is packaged under Nitrogen gas to prevent oxidation. Purging the bottle with Nitrogen gas is recommended after opening. Unfortunately, long term stability has not been determined, but is impacted by conditions and handling.

General description
Copper powder is a metal based powder that can be produced by electrolytic and non-electrolytic techniques. These processes include spray pyrolysis, chemical reduction in the presence of reducing agents, solvothermal and hydrometallurgical methods, and atomization.[1]
Application
Copper (Cu) based powder can be used for a wide range of industrial applications. Its electrical properties and thermal characteristics make it useful in the development of electronic and electrical devices. It can also be used for self-lubricated bearings, brazing, mechanical plating, and cold soldering.[1]
