Abstract：
The design and development status of Sm ₂Co ₁₇magnet blocks for two in-vacuum undulators (IVU20) at the SSRF with the same hybrid design has been described. By the technological improvement of some processes and comparison with the experimental Sm ₂Co ₁₇magnet blocks for the IVU25A, magnetic properties such as the intrinsic coercive force H _ciand the average magnetic moment Mare increased, the bend point magnetic field H _kvalue and pass rate are significantly increased, and the magnetic field uniformity of the magnet blocks are significantly improved. The basic developmental method of high uniformity Sm ₂Co ₁₇magnet blocks for IVU20 is presented. The magnetic field qualities of the magnet blocks, including the magnetic property, the magnetic moment distribution, the magnetization deviation angle and the magnetic field uniformity, basically satisfy the specifications of the two IVU20 in-vacuum undulators.
