Description

Cobalt-Chromiumalloy CAS NO 11114-92-4 is a high-performance metallic alloy composed primarily of cobalt and chromium, known for its exceptional strength, corrosion resistance, and biocompatibility. This material is critical in applications demanding durability under extreme thermal and mechanical stress, as well as in environments requiring long-term stability. It is an essential material for manufacturers in the aerospace, medical device, and industrial gas turbine sectors seeking reliable, high-integrity components.

Application

• Medical Implants and Surgical Instruments: A primary material for orthopedic implants (e.g., hip and knee replacements), dental prosthetics, and surgical tools due to its excellent biocompatibility and wear resistance.
• Aerospace Components: Used in the manufacturing of turbine blades, jet engine parts, and other high-temperature structural components where strength and oxidation resistance are paramount.
• Industrial Gas Turbines: Essential for hot-section components in power generation turbines, offering superior creep resistance and thermal fatigue properties.
• Chemical Processing Equipment: Employed in valves, pumps, and reactor parts that must withstand highly corrosive environments.
• Wear-Resistant Coatings: Applied via thermal spray techniques (e.g., HVOF) to protect surfaces from abrasion, erosion, and galling in industrial machinery.
• High-Performance Fasteners and Bearings: Used in applications requiring a combination of high strength, corrosion resistance, and reliability under load.

Quality Control

Our Cobalt-Chromiumalloy is produced under stringent quality management systems to ensure batch-to-batch consistency and compliance with critical industry specifications such as ASTM F75 (for castings), ASTM F90 (for wrought forms), and ISO 5832-4. Quality is verified through comprehensive testing including chemical composition analysis, microstructure evaluation, and mechanical property testing. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids and oxidizing agents. For long-term storage of finished components, a controlled, low-humidity environment is recommended to prevent surface oxidation.
