      STRAIGHT TUBE

      Material
      Copper
      Characteristic
      • ① Smooth and flat surface: The surface of smooth copper straight pipes is smooth and flat, without ripples or wrinkles. This smooth surface makes them widely used in some fields that require high-precision copper pipes, such as electronics, aerospace, and medical equipment.
      • ② High purity and good conductivity: Smooth copper straight pipes usually have high purity, with copper content usually reaching over 99%, which makes them excellent in electrical and electronic fields. Smooth copper has high conductivity and can effectively reduce the loss of electrical energy during transmission.
      • ③ Excellent ductility and plasticity: Smooth copper straight pipes have good ductility and plasticity, and can be easily stretched, bent, and processed into various shapes to meet different industrial needs. This characteristic makes smooth copper straight pipes highly flexible in manufacturing various copper products.
      • ④ Corrosion resistance: Compared to ordinary copper materials, smooth copper straight pipes have better corrosion resistance and can maintain stable performance in harsh environments. This feature gives it a unique advantage in some applications that require high demands on the external environment.
      Application
      Due to the above characteristics, smooth copper straight pipes have been widely used in multiple fields. For example, in the field of electronics, smooth copper straight pipes are used to manufacture circuit boards and connectors; In the aerospace industry, used for manufacturing components in high-temperature environments; In the field of medical devices, used for manufacturing precision instruments and equipment.
