Its excellent ductility (elongation ≥40%) allows cold bending, flaring and other processing and forming, and it has good corrosion resistance, making it suitable for conventional engineering scenarios such as water supply and drainage, gas transmission, etc. Compared with oxygen-free copper tubes, T2 copper tubes have more cost advantages while ensuring performance, and have outstanding cost performance.

The copper tube is available in three states: hard (H), semi-hard (H2) and soft (O). The hard tensile strength can reach 300MPa to meet different strength requirements. It is commonly used in air conditioning refrigerant pipes in the refrigeration industry, and can be used as busbars or grounding conductors in electrical engineering. It should be noted that there may be a risk of hydrogen embrittlement in a high-temperature reducing environment. At this time, it is recommended to upgrade to oxygen-free copper tubes (such as C10200). Its surface can be tinned or passivated to enhance corrosion resistance, and the scrap recycling value is as high as over 95%.
