There are two symmetrical standard bend sections been updated to super-bend sections in the storage of Shanghai Synchrotron Radiation Facility(SSRF). Photon absorbers made up of CuCrZr were used for absorbing radiation with very high power density in the super-bend sections. Meanwhile, CuCrZr absorbers were also used as beam chamber and pump port for the lattice of super-bend section is very compacted. The absorbing surface was designed as serrate structure in order to diminish the power density. CuCrZr was cold-forged before machining to enhance its strength, thermal conductivity and hardness. Friction welding is adopted for absorber fabrication to avoid the material properties of absorber deterioration. Rectangle flanges of absorbers were designed as step rather than knifer for vacuum seal. These high power density photon absorbers have been installed on the storage ring, both pressure and temperature being in accordance with design anticipation in the case of beam of 240 mA running.
