WHAT IS C17510 MATERIAL(COPPER NICKEL BERYLLIUM)?
C17510 Beryllium Nickel Copper alloy that is used primarily in applications that require high thermal or electric conductivity. This hard heat treatable copper alloy offers good strength and hardness characteristics and conductivity in the range of 45-60 % of copper with ultimate tensile and hardness properties approaching 140 ksi and RB 100 respectively.C17510 is an RWMA Class 3 material. The maximum amount of nickel is 0.30% and beryllium range is 0.2-0.6% with the balance of copper.
WHAT IS C17510 USED FOR?
Typical Uses for C17510 Beryllium Copper:
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
WELDING: Great for Spot and Seam welding.
COPPER-NICKEL-BERYLLIUM C17510
C17510 is designated as a RWMA Class 3 material which is assigned to copper alloys with high strength and good electrical conductivity. The material must be heat-treatable with good thermal conductivity and high tensile strength.
Class 3 C17510 is recommended for projection welding dies, flash and butt welding dies, current carrying shafts, and bushings. C17510 is recommended for highly stressed welder structural current carrying members and heavy duty offset electrode holders.
Class 3 C17510 is generally recommended for spot welding and seam welding steels, such as stainless steel, since it has high electrical resistance.
The most common uses for C17510 are in those applications that need high conductivity (electrical or thermal). Its ultimate tensile strength is 100- 140 ksi while its hardness approaches RB 100. The conductivity of C17510 is about 45-60% of regular copper.
The fabrication properties of beryllium copper alloy C17510 include: Cold Working, Hot Working, Welding, Forging.
Welding processes such as brazing, soldering, gas shielded arc welding, butt welding, seam welding, coated metal arc welding, and spot welding are recommended for C17510 copper alloy. Oxyacetylene welding is not recommended for this alloy. C17510 copper alloys can be hot worked between 648 and 885 degrees Celsius.
