TU1 is a type of oxygen-free copper that is commonly used in the production of copper sheets. Oxygen-free copper, including TU1, is characterized by an extremely low oxygen content, typically below 0.001%. This low oxygen content enhances the electrical conductivity, corrosion resistance and thermal stability of the material. tU1 copper sheet is typically used in electrical and electronic applications where high electrical conductivity is required.
The absence of oxygen in TU1 copper sheets reduces the risk of oxidation, ensures a long service life and maintains the electrical properties of the material over time. These copper sheets are used in the manufacture of electrical connectors, distribution systems and various components in the electronics industry.
