Nickel Plate

1. Visual InspectionColor & Shine: Real nickel is shiny silver-white. Fake pieces may look dull, yellowish, or gray.Surface: Pure nickel is smooth and rust-free. Fake sheets might feel rough or bumpy.2. Easy Physical TestsScratch Test: Scratch the surface with a knife. If it shows gold/red under the layer, it’s fake (plated). Real nickel stays silver.Weight Check: Pure nickel is ~15% heavier than fake nickel-plated iron (use a scale).Saltwater Test: Soak in saltwater for 4-5 hours. Green/yellow water = fake. No change = real.Magnet Test: Pure nickel is slightly magnetic. Strong magnetism = likely mixed with iron.3. Quick Chemical TestsNitric Acid Test: Drop nitric acid on the surface. No reaction = real nickel. Bubbles/color change = fake.Copper Sulfate Test: Rub the surface, then add copper sulfate. Turns purple-red? Likely fake (e.g., manganese steel).4. Professional TestingXRF (X-ray Fluorescence): Checks exact nickel content.Electron Probe Analysis: Detects surface layers (real nickel vs. plating).5. Extra TipsResistance Check: Pure nickel has lower electrical resistance than plated materials.Certification: Always ask for a quality report (ISO/ASTM standards) or brand labels.
