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.
Typical Uses for C17510 Beryllium Copper
On the basis of maintaining high strength, fatigue resistance, processability and other characteristics, it has particularly prominently improved electrical conductivity (up to 60% electrical conductivity). Under the current battery fast charging market background, it has a wide range of applications background:
- ELECTRICAL: Instrument Parts, Connectors, Heavy Duty, Relay Parts, Conductors, Switch Parts, Fuse Clips
- FASTENERS: Washers, Fasteners, Lock Washers, Retaining Rings, Roll Pins, Screws, Bolts
- INDUSTRIAL: High Flux Electromagnets, Thermal Transfer Plates, Welding Equipment, Springs, Die Casting Plunger Tips
- C17510 copper alloy is widely used as connectors, terminals, relays, springs, switches or construction materials, daily necessities, mechanical components, etc. as components of electrical/electronic equipment;
- C17510 beryllium nickel copper (NBC), the overall performance is better than chromium zirconium copper, and has good creep resistance, easy to process and shape. Used in resistance welding (butt welding), it can be processed into spot welding electrodes, electrode caps, electrode blocks, electrode arms, contact tips, electrode heads, sealing molds, etc. The advantages are good electrical conductivity, high hardness, and fewer repairs. It has a long life and can be widely used in industries such as automobiles, airplanes, machinery manufacturing, household appliances, hardware and electronics.

Note: In the Brush name:
- "A" represents the state of solution annealing (annealed, the alloy is in the softest state, easy to be stamped and formed, and needs to be cold worked or strengthened during the direct failure period);
- "H" stands for cold processing state (hard);
- "T" means that the material has been aging hardened by standard heat treatment (heat treatment means the state of aging strengthening heat treatment).
