How To Alleviate Internal Stress In Copper Terminal Blocks Through Heat Treatment Processes

copper terminal block undergoes cold working and forming during the manufacturing process, and multiple deformations will accumulate stress inside the material. As this residual stress is released naturally over time, it can cause minor displacements or warping in the structure, affecting the dimensional stability and assembly accuracy of the components.

In the field of metallic materials, annealing is a mature heat treatment technique. By heating the material to a specific temperature and controlling the cooling process, the grain structure is reshaped and internal stresses are released. This process is widely used in physical metallurgy for copper distribution block devices. According to metallurgical principles, during the annealing process, the dislocations and micro-defects inside the copper terminal strip crystal are adjusted, and recrystallization transforms the originally stretched grains into a more uniform shape, thereby reducing stress concentration.
