CuCrZr material has high heat load capacity, high yield strength and tensile strength, good thermal conductivity and low vacuum outgassing rate. At present, it has been used as a heat sink material in the heat exchanger of nuclear reactors. In this paper, based on the previous process exploration, the Front-end absorber is made of CuCrZr material, and the technical scheme of integral processing of flange and absorber is adopted. The thermal stress and deformation of CuCrZr absorber are analyzed by finite element method, and the processing of CuCrZr absorber is completed, and it is applied to the SSRF BL04Ucanted front end. After a period of electron beam cleaning, vacuum and temperature tests were carried out under high thermal load power, and the characteristics of the material in practical use were analyzed, which proved that CuCrZr material can be used in SSRF under high heat load.
