CCM Cobalt Chrome Moly - ASTM F1537 Alloy 1
We are suppliers of Cobalt Chrome Molybdenum (CCM) in round bar stock, commonly known as chrome moly steel, which is a non-magnetic, cobalt-chromium-molybdenum (Co-Cr-Mo) alloy used for machining and forging stock in the orthopedic implant industry. CCM maintains excellent wear resistance and is biocompatible, making it an ideal material for surgical implants. This material is commonly specified to ASTM F1537 Alloy 1 for forging and machining applications.

Chromaloy vs. Cobalt Chrome Moly
Cobalt-chrome-molybdenum alloys are widely used in orthopedic implants. The alloy has a much higher tolerance in the human body that cobalt or nickel, and thus, much less toxicity. CCM is a low carbon, wrought version of ASTM F75 cast alloy. Chromaloy steels are commonly used in bicycle parts, specifically body tubing, as the alloy is lightweight and 30% carbon, thus it is designated AISI 4130.
