DIN/EN CuNi2Be UNS C17510 Nickel Beryllium Copper Alloy 3

CuNi2Be C17510 (CDA 1751) Nickel Beryllium Copper is the mirror image of alloys C17500 in terms of its properties & Characteristics. C17510 is also primarily utilized in the industry applications that require most highly thermal or electrical conductivity, which features a Nickel alloying addition (1.40-2.20%). C17510 also offers good strength and hardness characteristics coupled with conductivity in the range of 45-60 percent of copper with ultimate tensile and hardness properties approaching 140 ksi and RB 100 respectively

Chemical Composition:
Be: from 0.20 to 0.60%
Ni: from 1.40 to 2.20%
Cu: Balance
Note: Copper plus additions equal 99.5% minimum.
