The Ultimate Tensile Strength of Beryllium Copper constant displays the value of ultimate tensile strength for beryllium copper UNS C17200 (1110 MPa).
The strength of a material is its ability to withstand an applied load without failure or plastic deformation. The capacity of a material to withstand loads tending to elongate is known as ultimate tensile strength (UTS).
Beryllium copper, also known as beryllium bronze, is a copper alloy that contains 0.5-3% beryllium. It is the strongest and hardest of any copper alloy. The UTS for beryllium copper UNS C17200 is 1110 MPa.
