Our work contains experimental and theoretical studies on the surface resistance of aluminium A999, A99 as a function of annealing temperature, frequency of electromagnetic oscillations, cooling temperature and processing technology. Results of investigation of Al-Be alloy surface resistance in a wide range of low temperatures are presented. The technology of the alloy production and treatment for getting the surface resistance lower then that of initial materials (Al, Be) is described. As we have found, this parameter remains to be a constant in a wide range of low temperatures.
