Which metals do not cause allergic reactions?

Fine metals: Most fine metals used in expensive jewelry (like pure gold, platinum, & titanium) do not cause contact allergies. The metals most likely involved are nickel, cobalt, and chromate which are often mixed with other metals. They are also found in insecticides, dyes/inks/paints, construction materials like cement, & leather tanning products. Patch testing can help identify dermatitis due to allergy.

Metal Allergy: Cheap metals tend to cause allergic reactions with nickel being the most common. Gold, silver, solid steel, platinum and titanium tend not to cause allergic reactions.
