Does The Annealing Process Of Copper Terminal Blocks Affect Their Conductivity?

Annealing removes residual stress and reduces crystal defects in copper materials, thereby optimizing the grain structure. The total conductivity of high-purity copper in the annealed state is often used as a benchmark for evaluating the performance of conductive materials; for example, the International Standard for Annealed Copper (100% IACS) is a commonly used reference for measuring the conductivity of copper.

In the application scenarios of copper terminal block, the uniformity of grains and stress release inside the material help maintain a stable resistance level. In other words, under normal current density, copper distribution block can maintain a stable conductivity. On the other hand, annealing also has a positive effect on machinability such as ductility and formability. This optimization of the internal structure will not cause a decrease in the conductivity of copper terminal strip.
