Beautiful and easy faded red rose gold manufacturing technology has been around for hundreds of years of 18 k gold. The principle is adjusting to remove 18 of 24 gold ratio of 6 copies of other metals. Copper to add more, the color is more red.The proportion of copper reduction has increased the proportion of silver color from red to pink.There are so many supermarket Aliexpress Rolex.
But compared to gold, produce the color of copper is more active metals.When the case contact with tap water, sea water, the water of the swimming pool chlorine, salt water, soap water, tap water, sea water.The swimming pool water, salt water or soapy water water containing the electrolyte and electrochemical reaction occurred in the copper and gold, will make copper anode corrosion.
The actual reaction is very weak, and only occurs on the surface, but the color on the surface of the copper etching, the beautiful red will fade away. The fade is evident in the experiments, under 40 degrees Celsius in saturated salt water soak ten days color will be dim.
Eternal rose gold rolex’s first generation of technology in order to let the rose gold color more durable, as early as September 4, 2003, rolex has applied for European patent EP1512765, inventors as many as eight people, the idea is to join the platinum, components to ensure that 75% of 18 k gold, red copper, 15% to 18% of the protection of copper 0.5% – 4% of platinum. This actually is the introduction of more swatches platinum technology principle, because of less amount of platinum, consume of copper electrolyte brine such contact is relatively less, slows down the color change.
Rolex latest eternal rose gold rolex technology this year on February 6, 2014 to apply for the latest eternal rose gold patent WO2014122235, inventor PASCAL DUBOS, JEAN FRANCOIS RICARD. Introduced a better thorough solution. In order to protect the present red copper, joined the more lively, indium, calcium silicon. If corrosion corrosion first these more lively, copper protection down, can protect the beautiful red and pink. We can see technical progress. Copper corrosion from the principle of volume is small, the color basic won’t refund.
