An alloy comprised of silver and other metals, formulated to exclude nickel, is increasingly prevalent in jewelry and other applications. This compositional choice caters to individuals with sensitivities to nickel, a common allergen often found in metal alloys. A typical example involves sterling silver, which usually contains 92.5% silver and 7.5% of other metals. When crafted to be free of nickel, the remaining 7.5% often consists of copper, zinc, or other non-allergenic alternatives.
The avoidance of nickel offers significant advantages, primarily reducing the likelihood of allergic reactions, such as contact dermatitis. This characteristic is especially important for items worn directly against the skin, ensuring greater comfort and wearability for a broader range of consumers. Historically, nickel was included in alloys for its hardening properties and cost-effectiveness; however, growing awareness of its allergenic potential has spurred the development and adoption of alternative formulations.
