Cobalt Chromium (CoCr) alloy tubes represent one of the most advanced material choices for industries that demand exceptional durability, temperature stability, and corrosion resistance. The alloy’s composition typically includes 60–65% cobalt, 25–30% chromium, and controlled additions of molybdenum, tungsten, and nickel to enhance hardness and oxidation resistance.
This unique blend results in a microstructure that retains high mechanical strength under extreme temperatures, offering excellent fatigue resistance and dimensional stability. CoCr alloys also resist oxidation and corrosion in acidic, saline, or high-temperature conditions, making them ideal for energy systems, medical devices, and aerospace applications.
At DLX, our imported Cobalt Chromium tubes are manufactured using vacuum induction melting (VIM) and precision cold-drawing technology to guarantee purity, consistency, and dimensional accuracy.
