TU1 Copper Tube is made from really pure copper. It's great at carrying electricity and heat, so it's perfect for things that need to work well and last. It's built to meet ASTM B68 and ASTM B75 standards. You'll usually find it in fridges, heating and cooling systems, electrical stuff, and anything else that needs to resist rust and move heat well.
TU1 Copper Tube is mostly pure copper (at least 99.9% pure). Because it resists electricity so well, it's great at conducting heat, so it's the best pick for heat exchangers, heat transfer setups, and electrical connections. The way it's made is by drawing copper into tubes without any seams. These tubes get processed carefully to give them great surfaces, the right size, and some strength. This guarantees the TU1 Copper Pipe will work consistently for a long time, even when things get rough.

Features & Advantages
Great at Conducting Electricity and Heat
TU1 Copper Tube is awesome at passing electricity or heat. This is ideal for when it is used for wiring, connectors, and heat exchangers. Because it's so conductive, things run better, waste less energy, and work better overall.
Seamless Build for Reliability
TU1 Copper Tube doesn't have any seams, so it's extra strong. It won't fail at weak points like tubes that are welded. Also, the insides are smooth, so there's less friction and wear when liquids or gases are moving through.
Dimensions that Fit Your Needs
TU1 Copper Tube comes in all kinds of sizes, like different diameters, thicknesses, and lengths. That means you can get exactly what you need for your project, so you don't waste stuff and things work better.
Long-Lasting Durability
Made with really pure copper and top-notch production methods, TU1 Copper Tube can handle crazy temperatures and pressures. Because it's so tough, it's great for jobs where things just have to work right.

FAQ
Q: Where is TU1 copper tube mainly used?
A: It is mainly used for manufacturing high-precision heat exchangers (such as engine coolers), conductive tubes for high-end power equipment, cooling pipelines for semiconductor manufacturing equipment, as well as vacuum and sealed components requiring high reliability.
Q: Compared with ordinary purple copper tubes, what unique advantages does TU1 have?
A: The core advantage of TU1 lies in its 'oxygen-free' property. It will not undergo 'hydrogen embrittlement' at high temperatures, making it more stable during welding and processing, with almost no risk of porosity or cracks. It is particularly suitable for critical components that require absolute reliability.
Q: Can I get custom sizes or shapes for my project?
A: Yes. In addition to standard round tubes, we can also provide special-shaped tubes such as rectangular and oval tubes, and can perform pre-bending or end forming processing according to your assembly requirements.
Q: Can TU1 copper tubes be used in high-pressure or ultra-low temperature environments?
A: Absolutely. Its seamless structure and excellent low-temperature toughness make it an ideal choice for high-pressure gas/liquid piping and low-temperature systems (such as deep cryogenic equipment, LNG-related equipment).
Q: How to confirm the quality of TU1 copper tube is qualified?
A: We provide a full range of original factory material reports with coverage of chemical composition, mechanical properties, and dimensional accuracy along with the goods. Additionally, we support re-inspection by third-party authoritative institutions (such as SGS, BV) or issuance of independent material certification reports.
