Beautiful and easy to fade rose gold manufacturing red gold 18K gold technology has been circulating for hundreds of years, the principle is very simple to adjust the 24 to remove 18 gold than 6 other metal ratio. Copper and more, the color is more red, the proportion of copper to reduce the proportion of silver to increase the color from red to pink. More dazzling rose gold on the left is platinum, the middle is the rose gold, the right is the gold But compared to gold, the uk replica watches color of the copper is more lively metal, when the case contact with tap water, sea water, swimming pool chlorine water, salt water, soapy water (tap water, sea water, the swimming pool water, salt water or soapy These electrolytes containing water and copper and gold electrochemical reaction, will be as anodic corrosion of copper off. This reaction is actually very weak, and only occurs in the surface, but the surface of the colored copper corrosion away, the beautiful red will fade away. This fade in the experiment is very obvious in 40 degrees Celsius saturated salt water immersion ten days will be significantly dim color. Rolex's first generation of eternal rose gold technology In order to make the color of pink gold more durable, as early as September 4, 2003 rolex replica uk applied for the European patent EP1512765, inventor of up to eight people, then the idea is to join platinum, component On to ensure that 18K of 75% of the gold, showing red 15% to 18% of copper, protect copper 0.5% -4% platinum. This technical principle is actually the introduction of more stable platinum, because the amount of platinum is relatively small, contact with brine electrolytes such as copper consumed relatively less, and slow down the color transformation. Rolex's latest eternal rose gold technology Rolex February 6, 2014 this year for the latest eternal rose gold patent WO2014122235, the inventor PASCAL DUBOS, JEAN-FRANÇOIS RICARD. Introduced a more thorough solution to the problem. In order to protect the red copper, adding more lively calcium, indium, silicon. If the corrosion first corrodes these more lively, the copper protects it down replica rolex watches and can protect the beautiful red and pink. From which you can see the continuous progress of technology. From the principle of corrosion of copper is very small, the color is basically not back.
