Embodiment Construction
[0017] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0018] The invention discloses a method for manufacturing a copper-aluminum composite panel. The method comprises the following steps:
[0019] Step 1, pre-processing;
[0020] Hang the soft pure copper plate of δ0.7×430×360 on the pre-treatment line for degreasing and degreasing treatment; including: degreasing tank-hot water tank-cold water tank-neutralization tank-cold water tank-drying tunnel Dry process processing.
[0021] Put the soft pure aluminum plate of δ3.0×430×360 into a box furnace, heat it to 350-420 degrees, and carry out degreasing treatment for half an hour.
[0022] Raw materials used in this embodiment: industrial pure copper plate (soft state) with Cu≥99.9%, industrial pure plate (soft state) with Al≥99.6%. According to the different thickness of the required product, the thickness of the raw material is selected: copper Cu is 0...
