Alloy Passes Biocompatibility Tests
An alloy from Hamilton Precision Metals is safe for use in implants.
After thorough investigation, a specialized alloy has been found to meet all criteria for implant compatibility as set forth under USP 24-NF 19 and ISO 10993 guidelines. Known as Havel, the material has passed independent, third-party testing for cytotoxicity, systemic toxicity, intracutaneous irritation, intramuscular implantation, skin sensitization, blood hemolysis, and pyrogenicity. Manufactured by Hamilton Precision Metals Inc. (Lancaster, PA), the alloy is available in foil or strip form with standard thicknesses of 0.0005–0.025 in. and widths to 7.5 in. Foils as thin as 0.000060 in. are also produced in up to 4-in. widths. During production, the foil is segregated from other materials to reduce airborne contamination.
