Gold Characteristic

  • Excellent conductor of electricity and heat.
  • The Most malleable of all metals – in fact gold is so soft it can even be molded by hand. Gold can be drawn to the thinnest wire approaching one atom in diameter.
  • It does not corrode or tarnish, unlike other highly conductive metals like copper or Silver.
  • Gold is biocompatibility, meaning it will not create adverse or toxic reactions when coming in contact with human tissue.
  • Gold is diamagnetic – almost zero reflected by magnetic field.
