Jewelry Test Magnet or Metal Testing & Specialty Magnets

Keychain and handle jewelry or metal test magnets for industrial and hobby use:

  • Jewelry & Pawn: Test gold and silver items to check for ferrous cores under plating.
  • Antiques: Check for iron present in brass, bronze, pewter, and copper pieces (which might indicate a forgery).
  • Industrial Recycling and Salvage: Sort austenitic  (300 series) from ferritic and martensitic (most 100, 200, and 400 grades) stainless steels. Sort ferrous from non-ferrous items where paint, chrome, or surface polishing makes a visual i.d. impossible.

Identify and sort steel grades and metal alloys that contain iron, nickel, or cobalt.
Identify/sort chrome plated items from polished aluminum, silver, and non-magnetic grades of stainless steel
Identify/sort solid brass and bronze from plated steel items (handy in the antique market and hardware store)
Identify/sort some types of costume (fake) jewelry, which often use steel or nickel as the base material under the plating.
