Abstract (en)

[origin: EP0238859A2] The object is to develop a corrosion-resistant copper material which can be used to receive flowing media such as water or steam. To improve the cavitation corrosion and stress-corrosion cracking, it is proposed to add to the copper blending components selected from the constituents aluminium/silicon, titanium/niobium, arsenic/phosphorus, nickel/chromium and germanium/gallium within certain limit values which are between 0.1 and not more than 8%. <IMAGE>
