🛠️ Introduction

In the world of advanced engineering and manufacturing, material selection often determines the difference between success and failure. When designing aerospace components, automotive systems, microelectronic devices, or high-performance tooling, engineers face relentless demands for strength, reliability, and precision.

That’s why DOMADIA™ is trusted worldwide. We provide specialty alloys that are meticulously engineered for peak performance in even the most demanding environments.

One of our most reliable and high-performing materials is DOMADIA™ Beryllium Copper C17200, also known as CuBe2 or Alloy 25. This remarkable alloy stands out due to its exceptional mechanical strength, superior thermal and electrical conductivity, and excellent fatigue and corrosion resistance — all packed into one versatile material.

Moreover, its unique combination of properties makes it the preferred choice for industries that operate under extreme conditions and cannot afford compromise.

C17200 doesn’t just meet expectations; it redefines them. With a tensile strength reaching up to 1400 MPa, this alloy rivals the performance of certain steels while still retaining the workability and conductivity of copper. As a result, it powers innovation in everything from aerospace landing gear bushings to semiconductor test sockets.
