Shenzhen High-Tech Industry Ltd. has been specializingin continuous electroplating since 1995. After a decade ofresearch, we developed black chromium nickel-plated copper. Now wehave a large supply of black chromium nickel-plated copper /Alunimum coil to manufacturers of flat plate solar thermalcollectors. Black chromium nickel-plated copper / Alunimum is avery desired selective surface using in solar absorber fins for aflat-plate solar thermal collector, which is very durable, highlyresistant to humidity or oxidizing atmospheres and extremetemperatures while being able to retain its selective properties.Because it has very good resistance to corrosion, low maintenancerequirements and high thermal stability. The descriptions are asfollows. Copper strip measurement (T x W x L): A. 0.15 x125 x 1840 (mm) B. 0.15 x 140 x 1840 (mm) C. 0.15 x 250 x 1840 (mm)D. 0.15 x 475 x 1840 (mm) l Rolling coil is available,regularly about 200--250Kg per roll. l Thickness is available from0.14/0.20mm. Absorption (alpha) a= 0.97 Emission (epsilon) e=0.10 . Flat Plate Solar Collector with three kinds of absorberfin made of Black Chrome Nickel plated copper, Aluminium coilregular size: 980(max width).We have other products: 1.tinned copper coil for radiator; 2.tinnedcopper net for battery; 3. steel board plated with copper and soon;4. Anodic Oxidation of Aluminum Coil for Solar Flat PlateCollectors;5.USB Type C 3.1 Plug Shell Tube &Connectors;6.Three - Layer Insulated Wire. Welcome to contact me for more information.
