Fabrication of Aluminum Clad Copper Tube by Planet Schràge Walzwerk Process

Abstract:

In the present paper, a fabrication process to roll-bonding aluminum clad copper tube(ACC) by Planet Schràge Walzwerk(PSW) has been introduced. Aluminum alloy(3003) as a outer tube layer and oxygen free copper(C12200) tube as a inner tube, were rolled to bond together using a PSW mill. Different specifications of ACC tube were selected to investigate the Al-Cu bonding layer thickness using scanning electronic microscope with EDX and bonding strength using peering test, and mechanical properties of ACC tube were also test. The experiment results indicated that Al-Cu composite layer is not only mechanical bonding but also metallurgical bonding with thickness of several micrometers. Moreover, tensile test indicated that the tensile strength of ACC was not less than 135 Mpa and elongation is about 35%, while peeling strength test showed that the two composite layers bond strength nearly arrived to 120 N/cm.
