Gold is a chemical element with a bright, slightly reddish yellow color in its purest form. As a precious metal and one of the least reactive chemical elements, it does not oxidize in air, so it remains stable under standard conditions and its electrical conductivity is constant over long periods of time. Gold plating can be used to enable metal pieces to be soldered together in situations where this would have not been previously possible and to increase wear resistance when it is mixed with cobalt. Its resistance to corrosion also makes gold electroplating suitable for connector pins, electrical switch contacts, and other applications where electrical contacts occur intermittently. ProPlate® regularly gold plates components for the medical & dental industries, energy and technology, telecommunications, semiconductors & electronics, oil & gas, and defense & aerospace industries. |

Underplate Recommendations
Metal ions from base metals such as brass, bronze, or beryllium copper, can disseminate into a gold layer applied on top and degrade the non-oxidizing and hardness properties of the gold. An anti-diffusion underplate such as electro-less or sulfamate nickel applied to the surface of the metal can prevent such occurrences and create a bright finish. Purity and Coating Thickness Gold of the highest purity is preferred for selective gold plating as impurities in the deposit can make soldering more difficult. Gold electroplating coatings should range between 50 and 100 micro inches for the best soldering. Hardness Grades
