What is Electroless Nickel with High Phosphorus?
Silchrome offer a semi-bright Electroless Nickel Plating containing between 10-12% Phosphorus content. Electroless Nickel produces a uniform coating that will increase the wear and corrosion protection of components.Being Lead and Cadium free, Electroless Nickel meets ELV, WEEE and Rohss regulations.
Why Choose High Phosphorus and not Medium Phosphorus?
Electroless Nickel using a High Phosphorus level has a higher corrosion resistance against chemicals that are acidic in nature such as Phosphoric Acid. High Phosphorus is the most ductile of the Electroless Nickel processes and is suitable for build up of thicker deposits. High Phosphorus Electroless Nickel is non-magnetic in nature whereas Medium Phosphorus Electroless Nickel is slightly magnetic. In terms of appearance, High Phosphorus is duller but is less prone to staining than Medium Phosphorus. Where corrosion is of more concern, you might select a Higher Phosphorus Content.
What Are the Advantages?
The main advantage of Electroless Nickel Plating is the uniformity of the coating. Components with threads, holes and complex geometry can be enhanced with a corrosion and wear barrier that will be even on all surfaces.
Electroless Nickel provides an excellent level of corrosion resistance and can provide protection against a wide range of sources including oxidation, seawater, petroleum as well as a number of different chemicals including Phosphorus Oxychloride, Benzoyl Chloride, Benzitrichloride, Phosphoric Acid and more. Electroless Nickel can be heat treated which further increases its hardness and wear resistance and this process can rival the outcome of Hard Chrome Plating for many applications.
Electroless Nickel is a very versatile coating used in a cross section of industries and has applications for automotive, petrochemical, petroleum and many other industries. Any component whose part life could be extended through added wear and corrosion resistance could potentially benefit.
