Abstract
A Cu—Be alloy according to the present invention is a Co-containing Cu—Be alloy, in which the Co content is 0.005% to 0.12% by mass, and the number of Cu—Co-based compound particles having a particle size of 0.1 μm or more that can be confirmed on a TEM image at a magnification of 20,000 is five or less in a field of view of 10 μm×10 μm. Furthermore, a method for producing a Cu—Be alloy according to the present invention includes a solution annealing treatment step of subjecting a Cu—Be alloy raw material containing 0.005% to 0.12% by mass of Co and 1.60% to 1.95% by mass of Be to solution annealing treatment to obtain a solution-annealed material.
