The performance of dispersion-reinforced copper is derived from the addition of alumina. The size of the alumina particles is only 3 to 12 nanometres and the particle spacing is about 50 to 100 nanometres, which is thermally stable*, even at temperatures close to the melting point of copper. as well as hardness and strength are well maintained.
