Will It Fade? The 2026 Gold Plating Durability Report

We put our pins through the torture chamber (Salt Spray Test) so you don't have to. Here is the data on Real Gold vs. Imitation Gold.

"Will these turn my customers' shirts green?"

It's a fair question. Cheap plating oxidizes, tarnishes, and fades. To prove the quality of our 2026 plating formulas, we conducted a standard ASTM B117 Salt Spray Test.

Salt Spray Test Results (ASTM B117)

We exposed different plating types (applied over Zinc Alloy and Brass bases) to a continuous 5% salt fog at 35°C. This simulates years of exposure to sweat, humidity, and air.

Plating Type24 Hours48 Hours72 HoursEst. Lifespan*
Real Gold (24K) (Recommended for Hard Enamel) No Change No Change No Change10+ Years
Nickel (Silver) No Change No ChangeSlight Dullness8-10 Years
Imitation Gold No ChangeMinor SpotsVisible Oxidation2-3 Years

*Estimated lifespan assumes normal indoor storage and occasional wear. High humidity or direct contact with chemicals (perfume) will reduce lifespan.

Which Plating Should You Choose?

Real Gold Plating

Uses actual 24K gold in the electroplating tank.

  • Jewelry-grade shine
  • Increases perceived value
  • Costs ~15% more

Imitation Gold

A tinted alloy that looks like gold but contains none.

  • Cheaper (Budget friendly)
  • Good for giveaways
  • Will fade eventually

Want Samples You Can Test?

Don't take our word for it. Request a sample pack containing both Real Gold and Imitation Gold pins so you can see (and test) the difference yourself.
