Auriferous Bronze Plating- is one of the largest selling Yellow bronze plating chemistry in India, giving an excellent brightness & yellow gold colour with an excellent corrosion resistant when used as an underlayer prior to gold specially in Micron gold plating for jewellery, watch, bath fitting components, writing instrument and optical goods giving a very fast gold colour which ultimately leads to saving in overall gold metal.
Auriferous Bronze is an electrolytic bronze process which provides yellow deposits. They are often used as precious metal undercoats for nickel-free, non-allergenic coatings
Yellow bronze plating containing Copper-tin (Cu-Sn) layers are well known and frequently used to avoid the use of nickel in many decorative and some technical applications. Consequently, the plating of yellow bronze has been with us for a long time.
Below are the excellent properties of Yellow bronze plating, such as:
- Good resistance to outdoor exposure,
- White and yellow (gold) color with a bright appearance,
- Hard and polishable,
- Diamagnetic properties for high frequency connectors, and
- Good wear resistance
- Wide range of applicable current density
- Good throwing power (similar to cyanide copper)
- Compact, shiny/bright coatings
- Good color distribution (constant color)
- Wide range of alloy composition possible
- Applicable for barrel, rack and high-speed plating
- Current efficiency (75 %)
- Stable electrolyte
- Long lifetime
Auriferous Bronze is a Yellow bronze plating electroplating processes for the deposition of alloy coatings of copper and tin or of copper, tin and zinc.
Auriferous Bronze coatings are characterized by an excellent thickness distribution even in the case of parts with complex shapes. The coating layer hardness are around are 400 HV. The layers are abrasion-resistant and are suitable for coating bearing shells or pistons. The coating is diamagnetic. Therefore, connectors for high-frequency technology reach very low intermodulation values in the mobile radio frequency range.
Auriferous Bronze is the best-in-class Yellow bronze plating chemistry.
Virjin Coat
Virjin coat- is a breakthrough in technology which helps in significant cost reduction by reducing gold & silver thickness and enhancing corrosion & wear resistance for the plated articles. It can reduce atleast 50% of gold usage. Virjin Coat is a water based nanotechnology protective layers which forms a nanometre thin film on Au/Ag surface to provide substantial anti-tarnish,
corrosion and wear resistance for gold/silver deposit, . It reduces the porosity of hard gold deposit. It can be used on Gold, Silver, Copper & Tin. It passes NSS, Artificial sweat, High Temp-Humidity & Nitric acid test. Virjin Coat provides the highest level of protection as compare to any protective layer/Anti tarnish currently available in market.
Virjin coat Silver & Gold Anti-tarnish is widely used in jewellery, watch industry, bath fitting industry, writing instrument, optical goods, connectors & telecom devices. The shortest/simplest process and broad operating window enable the mass production to be controlled easily. With this excellent chemistry we offer a special equipment VirjinX which reduces the chemical consumption by less wastages & extends bath lives, the overall lifetime of the electrolyte is extended considerably.
Tarnishing of silver and its alloys in certain environments is a persistent problem, inherently non-tarnishing silver has not been formulated yet, Virjin coat is one of the technologies which gives the highest protection as Silver & Gold Anti-tarnish in most of the environment and maintain the virginity of the metal.
Virjin coat provide long-term protection for gold, silver, copper and tin and permanently preserve metal brightness on jewellery, handles, rivets and decorative components, and reduces gold’s inherent porosity. By penetrating the grain structure, and prevent oxidation of the underlying nickel or copper.
Gold plating is primarily used in the electronics industry to provide a corrosion-resistant, electrically conductive layer on copper. It is also widely used in the jewellery industry.
Gold is the protective metal of choice because it has the greatest standard electrode potential. This makes it the most noble metal for plating with the highest corrosion resistance. Due to the scarcity and significant cost of gold, it is often sparingly applied, which can create lack of protection. This is problematic because it causes overall structural integrity issues when some areas corrode and degrade faster than others. Hence by applying Virjin coat Silver & gold anit-tarnish we can overcome the problem to a great extent.
Apart from jewellery Gold is also plated on electrical & functional component The reliability of electronic systems is greatly depended on the reliability of electrical contacts inside. Gold plating is usually adopted as the top finish of the electrical contacts in dry circuits because of its excellent stability and conductibility. But driven by cost pressure, gold finish becomes thinner and thinner. It is even considered to coat gold plating only on one side of a pair of contacts
Virjin coat is a protective layer which gives similar results even at half the thickness of gold as compare to usual plating thickness, thus giving substantial saving & the functional property are not impacted.
Tarnishing of Silver and alloys is a corrosion process manifested by the appearance of dark areas at material surface, an undesirable property in jewellery making. Main factors of surface tarnishing in silver and its alloys are numerous, but they could be classified according to compound types causing tarnishing. Leading groups are compounds containing sulfur, chlorine, and nitrogen Besides the concentration of gases containing the elements above, significant influence has physical factors like temperature, humidity, and illumination Reactions which lead to tarnishing are followed by oxidation reactions with atmospheric oxygen, which is confirmed by researches of tarnishing mechanisms. However Virjin coat Silver Anti-tarnish can gives a much longer life & protection in the environment.
Virjin Coat is the best-in-class Silver & Gold Anti-tarnish available globally.
It is widely used in jewellery, watch industry, bath fitting industry, writing instrument, optical goods, connectors & telecom devices. The shortest/simplest process and broad operating window enable the mass production to be controlled easily. With this excellent chemistry we offer a special equipment VirjinX which reduces the chemical consumption by less wastages & extends bath lives, the overall lifetime of the electrolyte is extended considerably.
Elite Bronze Plating-
Elite Bronze Plating- is a white bronze plating chemistry which gives a brilliant white colour similar to that of Rhodium plating giving an excellent brightness & excellent corrosion resistant and can be used as an underlayer for Nickel free substitute for jewellery, watch, bath fitting components, writing instrument and optical goods giving a very fast white colour.
