Embodiment 1
[0035] Copper alloy, cold deformation 60%, recrystallization temperature 850°C
[0036] Copper alloy is used as the base metal alloy for manufacturing composite plates. The thickness of the flying plate and the base plate are 5mm and 15mm respectively. The copper alloy is processed to the corresponding thickness according to the plate size specification, and the surface of the alloy is cleaned. See figure 1 (b), figure 1 (b) is the microstructure of the alloy matrix. The alloy matrix structure is mainly α solid solution, the grain size is from tens to hundreds of microns, the compactness is good, and there are no defects such as pores and impurities. It can be used as the base metal alloy for explosive welding for the next step process.
