To verify compliance, manufacturers may rely on standards and testing methods that measure nickel release rather
Absolute nickel absence can be difficult to guarantee because trace amounts can appear as impurities or due
Common non-nickel-containing materials include titanium alloys, certain cobalt-chromium alloys, aluminum-based alloys, nickel-free stainless steels (as marketed),
