Superior Medical Grade CoCrMo Alloy Sheet – ASTM F1537
Original price was: $100.00.$80.00Current price is: $80.00.
Medical Grade CoCrMo Alloy Sheet offers high strength, wear resistance, and biocompatibility, ideal for orthopedic, dental, and surgical applications.
Description
📄 Product Overview
The Medical Grade CoCrMo Alloy (Cobalt Chromium Molybdenum) Sheet is a premium-grade biomedical alloy specifically engineered for applications that require exceptional strength, wear resistance, corrosion resistance, and biocompatibility. Manufactured according to ASTM F1537 Alloy 1 and UNS R31537 standards, this high-performance sheet is widely used in orthopedic implants, dental prosthetics, cardiovascular devices, and other demanding medical applications.
This CoCrMo Alloy delivers superior performance in both static and dynamic loading environments, maintaining structural integrity under repeated stress cycles. Thanks to its unique combination of cobalt (Co), chromium (Cr), and molybdenum (Mo), this alloy offers a perfect balance of hardness, flexibility, and biological inertness, making it the preferred choice for critical healthcare devices.
🧪 Chemical Composition (Typical Range)
| Element | Symbol | Typical Content (%) | Function in Alloy |
|---|---|---|---|
| Cobalt | Co | Balance (~60%) | Provides strength, corrosion resistance, and wear resistance |
| Chromium | Cr | 26–30% | Forms a passive oxide layer for excellent corrosion resistance |
| Molybdenum | Mo | 5–7% | Enhances pitting resistance and improves strength in chloride environments |
| Carbon | C | 0.35% max | Increases hardness and wear resistance |
| Nickel | Ni | ≤1% | Improves toughness |
| Iron | Fe | ≤0.75% | Minor impurity control |
| Silicon | Si | ≤1% | Improves oxidation resistance |
| Manganese | Mn | ≤1% | Strength and deoxidation |
| Nitrogen | N | ≤0.25% | Grain refinement and hardness increase |
Conforms to ASTM F1537 Alloy 1 specification.
⚙ Mechanical Properties (Typical at Room Temperature)
| Property | Value | Standard Reference |
|---|---|---|
| Tensile Strength | ≥ 1000 MPa | ASTM E8 |
| Yield Strength (0.2% offset) | ≥ 827 MPa | ASTM E8 |
| Elongation | ≥ 8% | ASTM E8 |
| Hardness | 25–35 HRC | ASTM E18 |
| Modulus of Elasticity | ~ 210 GPa | ASTM E111 |
| Density | ~ 8.3 g/cm³ | ASTM B311 |
These properties ensure that CoCrMo Alloy sheets retain exceptional durability and shape stability, even in small or complex medical components.
💡 Key Advantages of CoCrMo Alloy Sheet
✅ 1. Superior Wear Resistance
The alloy’s high hardness and excellent tribological behavior make it ideal for joint replacement implants and other components exposed to sliding contact.
✅ 2. Outstanding Corrosion Resistance
Chromium’s passive oxide film protects against bodily fluids, saline environments, and sterilization cycles.
✅ 3. Exceptional Biocompatibility
CoCrMo Alloy exhibits minimal ion release in biological environments, significantly reducing the risk of allergic or inflammatory responses.
✅ 4. High Fatigue Strength
With a fatigue limit exceeding that of many stainless steels, the material performs reliably in cyclic loading conditions typical of orthopedic implants.
✅ 5. Proven Clinical Record
This alloy has been used in medical applications for decades, with a history of safe, reliable performance in human implants.
