ASTM F75 Cobalt Chromium Molybdenum Rod, UNS R30075 Cobalt Chromium Molybdenum Rod, 2.4975 Cobalt Chromium Molybdenum Rod, ASTM F75 Medical Grade Rod, Cobalt Chrome Moly Rod, F75 Surgical Alloy Rod, ASTM F75 CoCrMo Round Rod in India.

PM Industries is a manufacturer, supplier, and stockist of ASTM F75 Cobalt Chromium Molybdenum Rod, a biomedical alloy made for demanding surgical implant work. The specification, in its current ASTM F75-23 form, sets the chemical, mechanical, and metallurgical requirements for cobalt-28 chromium-6 molybdenum alloy castings (UNS R30075), which are supplied in rod form for machining into orthopedic parts. The nominal composition is roughly 58 to 68% cobalt as the base, 27 to 30% chromium, and 5 to 7% molybdenum, with carbon held to 0.35% or less and tight limits on nickel, iron, and other trace elements.

Chromium does much of the corrosion work, forming a stable passive oxide layer on the surface. Molybdenum adds resistance to pitting and crevice corrosion and lifts overall strength. Together they make CoCrMo rod a sound choice for long-term implantation, where the metal has to hold up in an aggressive physiological environment without breaking down.

ASTM F75 cast rod typically gives a minimum ultimate tensile strength of 655 MPa, a yield strength of 455 MPa, and elongation of 8%, with optimized processing reaching higher values. The alloy has strong wear resistance, high fatigue strength, and good ductility, which suits load-bearing parts such as hip and knee prostheses, femoral stems, tibial trays, and metal-on-metal bearing surfaces. It is also non-magnetic, so it works with MRI imaging, which matters in modern diagnostics.

The rod is produced by investment casting and then put through tight quality control to keep inclusion content low and the microstructure and grain size uniform. That controlled casting limits defects and supports biocompatibility. Implant manufacturers choose F75 because the alloy balances biocompatibility, mechanical durability, and tribological performance, which lowers the risk of wear debris and adverse tissue reaction.

Beyond orthopedics, CoCrMo serves in dental implants, spinal fixation devices, and cardiovascular applications. Processing keeps advancing too, including additive manufacturing powders made to ASTM F75 chemistry, which opens up patient-specific implant designs. With a long clinical record, strong corrosion and wear resistance, and the ability to take decades of cyclic load inside the body, ASTM F75 rod stays a benchmark material in medical metallurgy.

When ordering ASTM F75 CoCrMo rod, call out the diameter and tolerance, the length, the condition, and the testing and certification you need, including chemical analysis, mechanical results, and microstructure or inclusion checks. PM Industries supplies ASTM F75 cobalt-chromium-molybdenum rod in a range of sizes, each produced under strict quality control.
