GlidCop® AL-25 is copper that is dispersion strengthened with 0.5 wt% ultrafine particles of aluminum oxide. It is produced using an internal oxidation powder metallurgy process whereby aluminum oxide is formed in the Cu matrix. The matrix is hardened while the Cu electrical and thermal conductivity are minimally lowered. The aluminum oxide particles are very thermally stable and remain effective in strengthening the copper matrix and resisting grain coarsening even after very long exposures to high temperatures as in brazing or high temp duty cycles. GlidCop® is available with three different levels of Al2O3. Increasing the Al2O3 levels will increase strength but decrease conductivities. All three grades can be further strengthened by cold work. GlidCop® is available in a wide range of extruded and drawn shapes and sizes, including rounds, rectangles, wire, plates, tubes, and strip. Available on a limited basis in powder form.
