DOMADIA™ Beryllium Copper UNS C17510 – The Alloy That Bench-Presses Steel and Outsmarts Copper
Why settle for average when your material can do both the heavy lifting and high-voltage thinking?
DOMADIA™ Beryllium Copper UNS C17510 (CuNi2Be) is your go-to alloy when strength, smarts, and conductivity are non-negotiable. It performs like a bodybuilder with an engineering degree—strong, reliable, and precision-tuned.
Whether you’re designing aerospace components or high-end electrical connectors, our rods and bars don’t just meet specs—they show off.
Chemical Composition (UNS C17510 / CuNi2Be)
Element | Content (%) |
Copper (Cu) | Balance |
Beryllium (Be) | 0.2 – 0.6 |
Nickel (Ni) | 1.4 – 2.2 |
Cobalt (Co) | ≤ 0.35 |
Others | ≤ 0.2 |
This unique blend gives C17510 its exceptional thermal conductivity, corrosion resistance, and mechanical strength.
Applications: Trusted Across Critical Industries
Beryllium Copper UNS C17510 is the engineer’s secret weapon, especially in:
