Description：
Beryllium bronze is a copper alloy containing 0.5-3% beryllium and a small amount of nickel, chromium, titanium and other elements. Under complete heat treatment and cold working conditions, copper-beryllium is the hardest and strongest among all copper alloys (UTS up to 1250～1500MPa). It combines high-strength, non-magnetic and non-sparking characteristics. It is like many high-strength alloy plates of steel in mechanical properties. But compared with steel, it has better corrosion resistance (like pure copper).
