Description
ASTM F75 CoCrMo Casting Alloy Bar
⭐ Introduction
The ASTM F75 Cobalt Alloy Bar is presented here as CoCrMo casting-alloy material for procurement enquiries. ASTM F75 covers unfinished investment castings and casting-alloy shot, bar and ingot for implant applications. For a CoCrMo Rod enquiry, specify the intended casting route, dimensions and supplied condition; finished-device suitability is assessed by the device manufacturer.
For the Cobalt Chrome Molybdenum Bar, strength, wear and corrosion behaviour depend on the alloy chemistry, manufacturing route and condition. Confirm the ordered grade and batch inspection results for the F75 Cobalt Alloy Bar against the application requirements.
⚙️ Chemical Composition
The following composition values for ASTM F75 Cobalt Alloy Bar are catalogue references. Agree the standard edition and acceptance limits, then verify the supplied batch analysis before use:
| Element | Content (wt%) |
|---|---|
| Cobalt (Co) | Balance |
| Chromium (Cr) | 27.0 – 30.0 |
| Molybdenum (Mo) | 5.0 – 7.0 |
| Carbon (C) | ≤ 0.35 |
| Nickel (Ni) | ≤ 1.0 |
| Iron (Fe) | ≤ 0.75 |
| Silicon (Si) | ≤ 1.0 |
| Manganese (Mn) | ≤ 1.0 |
Chromium contributes to corrosion resistance, while molybdenum and the cobalt matrix influence strength and hardness and material behaviour. The ordered chemistry and supply condition of ASTM F75 Cobalt Alloy Bar require confirmation against the selected acceptance criteria.

🛡 Key Advantages
-
⭐ Strength and Toughness – Specify the loading and toughness requirements for the ASTM F75 Cobalt Alloy Bar in the ordered material condition.
-
🛡 Wear Resistance – Define the contact conditions, surface finish and wear-testing requirements for the intended component.
-
⚙️ Corrosion Protection – Confirm corrosion performance in the actual saline or service environment using the ordered material and surface condition.
-
🏥 Biocompatibility – For the Cobalt Chrome Molybdenum Bar, the device manufacturer evaluates the finished component, processing residues, surface condition and biological response for its intended use.
-
🔧 Manufacturing Flexibility – Confirm whether the order is casting-alloy feedstock or a separately specified forged, hot-rolled or precision-machined material route.
🏥 Medical Applications
Manufacturers considering the F75 Cobalt Alloy Bar for the following applications should specify the material route and finished-component acceptance requirements:
-
Hip and knee joint implants
-
Trauma fixation devices (plates, screws, rods)
-
Dental crowns, bridges, and partial dentures
-
High-strength surgical tools
For implant manufacturing, the ASTM F75 Cobalt Alloy Bar is a material input; finished-device design, wear, corrosion and biological evaluation determine suitability. A CoCrMo Rod enquiry should identify the ordered raw material and the downstream mechanical, corrosion and biological acceptance criteria.

The comparison table is a catalogue selection aid. Confirm the F75 Cobalt Alloy Bar requirements for the intended manufacturing and service conditions; medical-device acceptance requires assessment of the finished device.
🔧 Processing and Fabrication
-
Forging & Rolling: These are wrought processing routes. Define a separate wrought material specification when the requirement differs from F75 casting-alloy feedstock.
-
Heat Treatment: Specify the required thermal condition and confirm its mechanical test results for the selected material route.
-
Machining: Carbide tooling recommended for precision shaping of CoCrMo Rods.
-
Surface Options: Polished, turned, or ground, depending on customer requirements.
🏭 Quality Standards & Certification
For an ASTM F75 Cobalt Alloy Bars order, identify the applicable material specification and inspection-document requirements. The following references concern casting-alloy material and order documentation:
-
ASTM F75: casting-alloy bar, shot or ingot and unfinished investment-casting scope
