CuNiBeTi (BrNBT) Nickel Titanium Beryllium Copper Rod / Bar

A). CuNiBeTi (BrNBT) Details
CuNiBeTi (BrNBT) Nickel Titanium Beryllium Copper
CuNiBeTi ---BrNBT Nickel Titanium Beryllium Copper is the mirror image of alloys C17510 in terms of its properties & Characteristics. CuNiBeTi is also primarily utilized in the industry applications that require most highly thermal or electrical conductivity, which features a Nickel alloying addition (1.40-1.80%). 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 and with abt. 0.10% Titanium can refine and minimize the grain sizes of the beryllium copper alloys.
