优势
1️⃣ Excellent corrosion resistance: C44300-O61 tubes are made from copper nickel brass， which provides exceptional resistance to corrosion in both marine and industrial environments. This makes them suitable for applications where exposure to seawater， brine solutions， or corrosive gases is common.
2️⃣ High strength and durability: Copper nickel brass tubes exhibit good mechanical properties， including high tensile strength and excellent resistance to erosion， vibration， and stress. This makes them capable of withstanding high pressures and mechanical stress， making them suitable for applications in heat exchangers， condensers， and similar systems.
3️⃣ Thermal conductivity: Copper nickel brass has excellent thermal conductivity， making C44300-O61 tubes efficient for heat transfer applications. They can effectively carry heat away from sources and distribute it evenly， making them useful in heat exchangers， cooling systems， and HVAC applications.
4️⃣ Biocompatibility: Copper nickel brass is known for its biocompatibility， meaning it is suitable for use in medical and pharmaceutical industries. It does not cause adverse reactions in contact with human tissues or body fluids， making it ideal for medical gas， water， or refrigeration systems.
5️⃣ Easy to work with: Copper nickel brass tubes are easily fabricated and formed due to their malleability and ductility. They can be bent， rolled， machined， and welded into various configurations and shapes as per specific requirements.
