The color of karat gold also has the type of brownish red in addition to yellow, white with outside red.Traditionally, it is formed when Pd is added in gold
Billon just have reddish brown color and luster.But regrettably, the addition of Pd can form intermetallic compound.And such is closed
Gold is passing through the phenomenon that often changing colour, the serious perception for affecting jewellery after using some months.
Although China's bullion industry, especially first jewelry alloy is quickly grown, and due to starting evening, starting point is low, one
Also there is a big difference compared with world level on a little sport technique segments.Industry problems do not solve for a long time, not only affect related production
The market sales volume and usage experience of product, also it is serious limit such product international scope market occupancy volume.Exploitation is simultaneously
