Experts in precious metals plating for jewlery and fashion



In order to support our clients, Royalegroup lab technicians share their knowledge and experience providing on request the following analysis, complying to the most recent regulations:

Metallurgical trials

  • Chemical analysis on metallic materials (determination of elements and contents, impurities and titles)
  • Specific analysis for metallic powders (granulometric profile, morphology and apparent density)
  • Wear trials (mechanical stress) and corrosion on metallic materials
  • Microscopy (electronic and optical with analysis of the images)
  • Physical/mechanical (color coordinates, hardness and traction trials, thermogravimetric analysis; surface and roughness of the scanned objects determination)
  • Preparation of samples and services (resin inglobation, casting and rollings)

Trials on baths

  • Hull cells
  • Deposit trials
  • Cathodic efficiency measurement
  • Tarnish trial
  • Stress test

Chemical analysis for the galvanic sector

  • Determination of metals in the baths, including impurities and chemical-physical characteristics (ph, bath density)
  • Determination of the deposit nature (alloy % and deposit titulation)
  • Determination of deposit thickness
  • Morphology of plating deposit
  • Wear trials (mechanical stress) and corrosion of plating deposits
  • Deposit color coordinates
