Gold Alloy Plating Processes
AURUNA 539 and 539LC produce gold alloy deposits of 99.7% gold, alloyed with cobalt. The ultra bright deposits have good corrosion and abrasion resistance with a hardness of 150 - 220 HV.
The processes exhibit excellent deposit distribution.
A high speed cobalt gold alloy process for reel to reel and tab plating applications.
Gold content is 12 g/l and deposition rate is up to 11 µm per minute.
A weakly acid, decorative gold/iron/indium alloy plating solution, producing a deposit of approximately 1-2 N.
AURUNA 220 produces a pale yellow, bright 14 carat gold/nickel/indium alloy deposit ideally suited for decorative applications.
With gold content 4 g/l and a deposition speed of 0.6 µm per minute the process is suitable for both rack and barrel applications.
A high efficiency nickel-gold alloy plating process containing 0.3% nickel.
The deposits show low and stable contact resistance and good wear resistance whilst showing a wide operating window.
It can be used in both rack and barrel and meets ASTM B488: type 2 - 3, code C.
AURUNA 527 produces a nickel gold alloy deposit and has been designed specifically for barrel plating.
This gold bath displays excellent metal distribution characteristics. The bath has a gold content of 2 - 5 g/l and a deposition rate of 0.02 - 0.1 µm per minute.
A weakly acid, hard gold plating electrolyte with high current efficiency.
This nickel alloyed gold plating solution is ideal for both printed circuit and decorative applications producing a yellow coloured deposit.
AURUNA 531 is a weakly acidic electrolyte for the deposition of bright, hard gold coatings – deep yellow in colour.
The nickel gold alloy coatings have a hardness of 140 - 150 HV and display good abrasion resistance.
AURUNA 535 is a weakly acidic electrolyte producing deposits containing 99.8% gold. The gold is alloyed with nickel and the resulting deposit has a hardness of 140 - 150HV.
Both the 535 bath and the 535LC bath (low concentration) may use stainless steel anodes.
A new high speed hard nickel-gold alloy process designed for electrical contacts.
Low porosity and wear resistance are features together with an extended operating range.
ASTM B-488: type2-3, code C.
A weakly acid, nickel/cobalt alloyed gold plating electrolyte specifically designed for the bathroom industry. The yellow-grey coloured deposit has good corrosion and abrasion resistance as well as good hardness.
A decorative, deep-yellow iron/gold alloy deposit is produced by AURUNA 536 which is suitable both decorative and technical applications (MIL-G 45204 classification I-11C).
The solution has a gold content of 11 g/l and has a deposition speed of 1 µm per minute.
These electrolytes produce a gold deposit of 99.7% gold alloyed with iron. Crack-free coatings of up to 10 µm can be achieved with a hardness of 150 - 170 HV.
A weakly acid, nickel/indium alloyed gold plating electrolyte producing a pale yellow 1N coloured deposit.
Deposits have good corrosion and abrasion resistance making them ideal for decorative applications.
Similar to AURUNA 221 but producing a light 2N colour.
A high speed, nickel-indium alloyed gold plating electrolyte producing a pale yellow colour.
As AURUNA 230 but producing a light yellow 2N colour.
A range of alkaline-cyanide, silver alloyed gold electrolytes producing thick coatings of gold.
