PROBLEM TO BE SOLVED: To achieve an improved method for manufacturing copper based precipitation hardenable alloys, such as copper-chromium (CuCr), copper-chromium-zirconium (CuCrZr) and copper-zirconium (CuZr), by using continuous casting for an elongated casting, such as a rod, instead of a cast billet and thus to shorten the manufacturing process. SOLUTION: The method contains: a step where an elongated piece made of a copper based precipitation hardenable alloy such as copper-chromium, copper-chromium-zirconium and copper-zirconium and having an essentially circular, rectangular or ring-like cross-section is cast by continuous casting; a step where the cast piece is drawn, and; a step where at least one aging treatment is carried out for the final product.
