Straight Tube
- 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.
- 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.
- 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.
- 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.

Frequently Asked Questions
What materials are these plain and straight tubes made of?
Both our Plain Tubes and Straight Tubes are manufactured using high-quality copper, including OFC (oxygen-free copper) options for enhanced corrosion resistance.
What are the primary applications for Plain Copper Tubes?
Plain copper tubes are widely used in the AC and refrigeration industries, LNG gas installations, medical care, building construction, and shipbuilding.
What makes Straight Copper Tubes suitable for high-precision industries?
Straight copper tubes feature a smooth, flat surface without wrinkles, high purity (over 99% copper content) for excellent conductivity, outstanding ductility, and strong corrosion resistance. This makes them ideal for electronics, aerospace, and medical devices.
Are the copper tubes corrosion-resistant?
Yes, both tube types possess high corrosion resistance. Specifically, our Oxygen-Free Copper (OFC) tubes deliver superior performance against corrosion in harsh environments.
What ranges of outside diameters and wall thicknesses do you offer?
For Plain Tubes, we offer outside diameters from 3.60mm to 28.58mm with wall thicknesses from 0.25mm to 2.00mm. For Straight Tubes, we offer outside diameters from 3.60mm up to 108.00mm with wall thicknesses from 0.25mm to 3.50mm.
