We produce C17200 beryllium copper.The good corrosion resistance of copper and its alloys is well known. Among many types of copper alloys, beryllium copper has corrosion resistance. For brass and zinc cupronickel, the fatal stress corrosion embrittlement, while beryllium copper is almost unaffected. In seawater, the corrosion resistance of beryllium copper is equal to or even higher than that of aluminum copper and copper-nickel alloys, which are very practical in areas where corrosion resistance and hardness are required. More significant is that it has the necessary corrosion resistance and mechanical tension at the same time. When the surface of beryllium copper is densely distributed by the oxidation produced by aging hardening, a protective film is formed. Therefore, the oxidation resistance of beryllium copper is also excellent at high temperatures. C17200 beryllium copper is your good choice.
