Medical Device Materials: Titanium, Stainless Steel, Cobalt Chrome and Polymers

'Titanium' is not a complete purchasing specification. Alloy, condition, product form, heat, supplier evidence and the device's intended use define the material record that manufacturing must preserve.

'Titanium' is not a complete purchasing specification. Alloy, condition, product form, heat, supplier evidence and the device's intended use define the material record that manufacturing must preserve.

Start with the controlled specification

Material selection is a design and regulatory decision. A recognized standard can define chemistry and properties, but the manufacturer must apply the current approved specification and determine which edition or acceptance criteria control the product.

Machinability is not the only question

Titanium heat and tool loading differently from stainless steel; cobalt-chromium alloys present their own cutting and finishing challenges; polymers can be sensitive to heat, moisture and handling. Process planning must protect both geometry and material condition.

Preserve traceability

Heat or lot identity, incoming acceptance, cut-piece control, scrap segregation and outside-process records should connect to the finished device history. Re-marking or relabeling material without a controlled record breaks the chain that a certificate was meant to support.

Validate substitutions

A commercially similar grade is not automatically interchangeable. Changes in supplier, specification, product form or process route can require formal evaluation under the manufacturer's quality system. MBB describes common manufacturing behavior, not material approval for a device.
