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.

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]
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]

Carbon monoxide (CO) produced in many large-scale industrial oxidation processes is difficult to separate from nitrogen (N2), and afterward, CO is further oxidized to carbon dioxide. Here, we report a soft nanoporous crystalline material that selectively adsorbs CO with adaptable

Lytic polysaccharide monooxygenases (LPMOs) exhibit a mononuclear copper-containing active site and use dioxygen and a reducing agent to oxidatively cleave glycosidic linkages in polysaccharides. LPMOs represent a unique paradigm in carbohydrate turnover and exhibit synergy with hydrolytic enzymes in biomass
