C17510 High-Conductivity Beryllium Copper (Alloy 3)
Also known as Alloy 3, UNS C17510
C17510 (Materion Alloy 3) is a high-conductivity copper-nickel-beryllium alloy that offers good strength together with high electrical and thermal conductivity, good stress-relaxation resistance and good strength at elevated temperature. It suits parts that must carry current or move heat rather than take the highest loads.

All Beryllium CopperFrequently asked questions
- Should I choose C17510 or C17200?
- Choose C17200 (Alloy 25) when strength comes first and C17510 (Alloy 3) when conductivity comes first. Materion lists Alloy 3 at 45–60% IACS against 25–30% IACS for Alloy 25.
- Is C17510 the same as Alloy 3?
- Yes. C17510 is the UNS number of Materion Alloy 3.
- What is the price of C17510?
- Prices for C17510 are quoted per enquiry, because they depend on the grade, the form (rod, plate, strip and so on), the size and the quantity. Send those details through the quote form, by phone on 02-728-0150 or on LINE @vanintertrade, and we will quote.
