About C17510
UNS C17510 is a nickel-beryllium copper alloy with a nominal composition of 0.5% Beryllium, 2.5% Nickel, balance Copper.
C17510 is designated as a RWMA Class 3 material which is assigned to copper alloys with high strength and good electrical conductivity.
Standard Specification for Copper-Cobalt-Beryllium Alloy, Copper-Nickel-Beryllium Alloy, Copper-Nickel-Lead-Beryllium Alloy, and Copper-Nickel-Cobalt Alloy Rod and Bar
This specification establishes the requirements for copper-cobalt-beryllium alloy (UNS No. C17500), copper-nickel-beryllium alloy (UNS No. C17510), and copper-nickel-lead-beryllium alloy (UNS No. C17465) rods and bars in straight lengths. Tempers available under this specification are: TB00 (solution heat treated (A)), TF00 (precipitation hardened (AT)), TD04 (solution heat treated and cold worked: hard (H)), and TH04 (hard and precipitation heat treated (HT)). Materials shall be tested and adhere to mechanical (tensile strength and Rockwell hardness), electrical conductivity, and chemical composition requirements.
