Products Description
Copper-nickel alloy heat exchangers/condensers are renowned for their superior corrosion resistance, wear resistance, and erosion resistance. This alloy also possesses good strength, weldability, and machinability, and is known for its excellent oxidation resistance. Copper-nickel alloys are the highest copper and nickel content alloys, containing no other elements, and also 1% zinc. Nickel plays a crucial role in the physical and mechanical properties of copper-nickel alloy heat exchangers and condensers.

Products Description
Copper-nickel alloys possess excellent thermal stability and conductivity. This particular grade of copper-nickel alloy has a high melting point and a large coefficient of thermal expansion, making it suitable for temperature control in heating equipment. Furthermore, it exhibits good resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking. Copper-nickel alloys perform optimally in reducing environments such as those containing chlorides, sulfides, alkalis, and other corrosive chemicals.
Quality Assurance – At GNEE, quality is our top priority. We employ a rigorous quality management system to ensure all products meet international quality standards. Our quality team conducts meticulous inspections at every stage of production. In addition, finished copper-nickel alloy heat exchangers/condensers undergo numerous parameter tests. Some tests include thermal performance testing, natural circulation stability testing, mechanical property testing, hardness testing, material property testing, and chemical composition testing. Other tests include destructive/non-destructive testing, intergranular corrosion testing, ultrasonic testing, radiographic testing, pitting corrosion testing, and visual inspection.
Packaging Standards – We pay close attention to every aspect of the packaging process. We use high-quality packaging methods such as wooden crates, tins, large cages, pallets, and cartons. In addition, we have installed extra support structures to prevent bumps and damage during the outlet process.
We can supply copper-nickel alloy heat exchangers/condensers in a variety of standard, specifications, and custom sizes.
