Cold Extrusion Forming of Copper/Aluminum Clad Composite
The cold extrusion forming of copper/aluminum clad composite based on the low pressure casting billet is presented in this paper. The technology was studied by using the experimental investigation and the finite element method. The drop-in phenomenon occurred in aluminum during the extrusion forming process. The product will be having good quality when the extrusion ratio is 5.45 and the extrusion modular angle is 30°. The crack appeared on the head of product when the extrusion ratio and extrusion angle is large than the aforementioned values.
