Copper:Standard 102 OFC (Alternatively 110 ETP or 101 OFHC)or tailored
Alumium:Al1050 (Alternatively Al100) or tailored
Standard: Upon ISO, ASTM, ASME, JIS, NB, JB
Copper and Aluminim have good electricity and heat conduction performance. They are the basic material for power transmission and heat transfer engineering. With the shortage of copper resource, using aluminium to save copper and replace copper is a inexorable trend.
Compared with copper, the welding performance of aluminium is worse and its surface contact resistance is bigger. So it is difficult to use aluminium to replace copper in some components. When clad one layer of copper in the aluminum, the clad conduct material can improve Aluminium's contact resistance; Enhance the welding performance of the aluminium and anti-corrision of copper and aluminium contact surface. All these decreased the cost and lowered the weight. Many important components like heat sink, tube solar and transition plate in heat exchanger manufacturing, power transimission and electrical appliances are made by copper and aluminium clad material.
