Terminology Used in This Section:

Electrolytic Tough Pitch (ETP): A refining process that utilizes electrolysis ensures exceptional purity, typically around 99.9% copper. The term “tough pitch” denotes the controlled addition of a small quantity of oxygen (approximately 0.02–0.04%) during the manufacturing process, which enhances the metal’s soundness by minimizing gas porosity. While the presence of oxygen improves the material’s electrical and mechanical properties, it renders ETP copper unsuitable for applications that require welding or high-vacuum environments, where oxygen-free grades are preferable.
