Technical scheme is as follows：
A kind of novel copper-aluminium composite, its preparation process comprise the following steps：
（1）By copper coin and molten aluminum liquid, casting is molded under the protection of inert gas, and it is the primary compound of 7 ~ 12mm to obtain thickness
Material；
（2）Preliminary composite is rolled under inert gas shielding, the change of material temperature turns in rolling first protects at 700 DEG C
Warm 3min, thereafter uniform decrease in temperature to 500 DEG C, insulation 2min, thereafter uniform decrease in temperature to 400 DEG C, insulation 3min, thereafter with 10 ~ 20
DEG C/min rate of temperature fall is down to normal temperature, continue to be cold-rolled to obtain the secondary composite material that thickness is 5 ~ 7mm；
（3）Secondary composite material is heated using 10 ~ 15 DEG C/min heating rate, stopped when being warming up to 500 ~ 600 DEG C
Continue to heat up, be incubated 5 ~ 10min；
（4）Thereafter 200 ~ 400 DEG C are cooled to 5 ~ 10 DEG C/min speed, are incubated 30 ~ 60min；
（5）By step（4）Obtained material carries out hot rolling immediately, and drafts is 0.5 ~ 1mm, and hot-rolled temperature is 200 ~ 400 DEG C；Heat
Normal temperature is down to after the completion of rolling, obtains the novel copper-aluminium composite by post processing.
Preferably：The step（3）~（4）Including procedure below：
（3）Secondary composite material is heated using 10 DEG C/min heating rate, stops continuing to rise when being warming up to 550 DEG C
Temperature, it is incubated 5 ~ 10min；
（4）Thereafter 300 DEG C are cooled to 10 DEG C/min, are incubated 60min.
It is also preferred that：The step（3）~（4）Including procedure below：
