Description
National High Magnetic Field Laboratory (MagLab) uses Cu matrix composites to build high field magnets. One of the composites is made from alumina- reinforced Cu. The fabrication of these composite conductors requires pure Cu cladding or container, which contains the Cu+ alumina composites, leading to a macro-composite. The cladding has lower strength and higher electrical conductivity than Cu+ alumina composites. In out pulsed magnets, we have been using macro-composite. In our tests, however, we sometimes tested only Cu+alumina core. This paper reports our work on the impact of cladding on mechanical properties of Cu+alumina composites. We will discuss the important for testing samples with and without cladding.
