Silver Plating  [silver plating] provides a coating which is matte-white in appearance. This finish provides good corrosion resistance, but also has the tendency to easily tarnish. Though inferior to gold plating, silver plating provides many of the same characteristics at a more economical price. Silver is a great coating for solderabilty of small parts, it also provides a good coating for parts that require low electrical resistance, and lastly, silver provides great lubricity. At Novafin we have two fully automatic silver electroplating baths which can deliver Bright Silver and precision Selective Functional Area (Partial) Silver Plating.

Nickel provides:

Excellent resistance to corrosion.
Provides a strong, durable, and malleable coating.
Versatile finish.
Bright finish.

Bright nickel solution is used to obtain a decorative finish. Nickel plate is protective, mirror bright or dull, and smooth. It can be applied to steel, brass, copper, powdered metal and zinc die castings.

Low-Stress Nickel Plating Or Sulfamate Nickel Plating 
We offer low-stress, 99.9% high-purity sulfamate nickel plating. Sulfamate nickel plating excels where a highly ductile, low-stress nickel deposit is preferred such as flexing or crimping applications as well as joining functions such as soldering, brazing, epoxy bonding or welding.  Sulfamate nickel plating also serves as an excellent under plate for tin plating and silver plating
Low-Stress nickel plating produces a 99.9% pure deposit devoid of organic brighteners or levelers. The high purity of the deposit affords temperature resistance up to the 1400C+ melting point of pure nickel. The deposits have a full matte appearance with a slight yellow or golden cast not known for decorative appeal. The deposits have extremely low deposit stress that can be in the compressive range. The low stress of sulfamate nickel plating yields nickel deposits with ductility, elongation and machinability far superior to other nickel deposits.
Sulfamate nickel plating excels in joining applications including brazing, soldering, over moulding, epoxy bonding and welding. The high purity and lack of co-deposited organics improves the wetting of the nickel deposit when soldering and makes sulfamate nickel plating the preferred under-plate and diffusion barrier when tin plating and silver plating for solderability or brazing. In addition, the unlevelled matte surface makes sulfamate nickel plating the choice for adhesion in over-moulding or epoxy bonding applications. It is normally a dull grey to dull silver colour depending upon the finish of the plated part. 

Electroless Nickel Plating
E/Ni can be plated over a wide variety of metals including aluminium, titanium, mild steels, stainless steel, hardened steel, copper, brass and zinc die-cast. Electroless nickel provides:

Uniform coating on most complex,and/or Irregular surfaces. 
Improves resistance to galling. 
Provides a hard, wear resistant surface.

Electroless Nickel is an auto-catalytic chemical reduction coating requiring no electricity to process.
The phosphorus content of the bath determines the hardness and corrosion resistance of the coating. 
With the addition of a baking operation following the plating, hardness of coating is enhanced.

A process with a high degree of plating uniformity, Electroless Nickel allows for the finishing of complex parts since all wetted surfaces are plated. A wide variety of substrates can be finished with Electroless Nickel and is ideally suited for engineering components. The deposit is harder than electrodeposited nickel and offers excellent wear and corrosion resistance.

Tin plating is a process which provides a bright silver finish and is composed of at least 99.5% tin. This type of plating is commonly used to provide a surface with great solderability and some corrosion protection. Typically tin plating is used in the printed circuit board industry, the food industry, as well as for decorative purposes. The main application for tin plating in the circuit board industry is to make use of the tin's solderability. On such substrate materials as brass or zinc die cast it is necessary to use a barrier layer of either copper or nickel to impede the migration of the zinc into the tin deposit. This barrier layer will further increase the shelf life of the tin plating on these substrate materials.
Base Materials that Tin Plating can be applied to include steel, stainless steel, brass, copper, zinc die cast, and aluminium.

Electro deposited tin is non-toxic, ductile, and resistant to both corrosion and tarnishing. Tin plating provides a uniformly thick coating which is highly conductive and 100% solderable, making it an excellent choice for electrical contacts. The high throwing power of our fully automatic electro-plating tin bath makes it possible to plate items of unusual shapes with exceptional reliabilit.

Zinc Cobalt Plating At Novafin we provide unmached quality Cobalt-Zinc-Trivalent and Zinc-Nickel-Trivalent type nickel alloy electroplating services.

Zinc-Cobalt Provides: 
Enhanced Corrosion Resistance. 
A remarkably bright luster. 
A uniform ductility that will withstand up to 6 times the corrosion resistance of conventional zinc plating. 
Ductility.

Copper Plating provides a coating which is reddish in appearance. Copper can range from a matte to bright finish which is often depends on the surface brightness of the part. This finish provides good corrosion resistance, but also has the tendency to easily tarnish. Copper is a great coating for solderabilty of small parts, and it also provides an economical finish for parts that require low electrical resistance.
Brightness of part can depend greatly on surface finish of base material.
