The prepared Al2O3/CU composites have a good cold deformation ability. After 50% cold deformation, the brinell hardness of the Al2O3/CU composites significantly increased, reached 116, but the electric conductivitychanged a little.

• 由反应铸造法制备的Al2O3/Cu复合材料的冷锻性能良好,经过50%25冷压变形后,其硬度可以达到116(HB),变形量越大,硬度越高,而电导率则变化不大。
