Contraception, 1979
Epicutaneous tests with copper, nickel and cobalt were performed in 37 patients using copper IUD who had shown side-effects to the IUD. None of them was allergic to copper; four were allergic to nickel and one to cobalt. Metal allergy was not considered to be the cause of the side-effects in any of the patients.

Current Opinion in Gastroenterology, 2007
Reports of the neurologic findings in adults with acquired copper deficiency as well as the development of novel models for Menkes disease have permitted a greater understanding of the role of copper in the central nervous system. A role of mitochondrial copper homeostasis in cellular energy metabolism suggests roles for this metal in cellular ...

In 1958 exposure tests were started in Sweden to gain knowledge of the natural patination and the corrosion behavior of copper and copper alloys when used outdoors. The investigation covered 36 alloys in sheet or rod form: 5 coppers, 20 brasses, 5 phosphor bronzes, 1 silicon bronze, 1 aluminum bronze, 1 cadmium bronze, 2 nickel-silvers, and 1 free ...

Copper and its alloys are widely used because of their outstanding conductivity, workability and resistance to corrosion. Selected alloys from the principal groups of copper-based materials are presented, including unalloyed coppers, high-copper alloys, brasses, and bronzes, highlighting the capability of this class of materials. The description of the
