The following are the characteristics: 1. The Copper Panel is made by vacuum smelting process technology, high purity copper, good thermal conductivity, and no defects such as pores, sand hole and unconsolidated. 2. Safe and reliable copper welding process makes the welded joint satisfies the requirment of high temperature and strength. 3. The perfect structure design and appearance meet the requirment of field use and completely replace the imported products. 4. Perfect internal waterway structure design, uniform waterway, closely mating, low flow resistance, and good cooling effect. Technical Parameter Chemical Composition:Cu=99.93% O= 30ppm H =1.0ppm Conductivity:=94%IACS Pressure test:Water pressure 1.5MPa maintain 30 min without leakage.
