Anodize (MIL-A-8625F TYPE II CLASS 1/2)
Anodizing is a metal finishing process that uses oxidation to cover the surface of metal with a layer of aluminium oxide. Anodizing offers an excellent corrosion protection that is strong enough to withstand 336 hours of Salt Spray Test. Making it suitable for items that are kept outdoors/indoors. It will greatly improve the corrosion resistance if apply a layer of anodizing as a primary coat.

Electroless Nickel Plating ( ASTM B733-97 )
Electroless nickel plating is a process that is capable of depositing an even layer of Nickel-phosphorus alloy on a wide range of substrates. It offers corrosion protection and increases the item’s wear resistance. The metallurgical properties of the alloy highly depend on the percentage of phosphorus, ranging from 5–12%.
High phosphorous electroless nickel offers a pore free barrier coating that protects the underlying substrate from damage on impact while also providing high corrosion resistance. Meanwhile, Medium phosphorous electroless nickel is used to achieve corrosion resistance together with a better wear resistance.
Gold Plating (ASTM MIL-DTL-45204D)
Gold plating is a method of depositing a thin layer of gold onto the surface of another metal. Its often used in electronic products to provide a corrosion-resistant layer with excellent electrical conductivity.
Chromate Conversion (MIL-DTL-5541F TYPE II CLASS 1/3 )
Chromate conversion coating is a passivation process used on aluminum. It results in a thin film protecting the aluminium metal surface providing corrosion resistance that can withstand up to 168 hours Salt Spray Test. It preserves conductivity after process and also improve the item’s adhesion with wet paint or powder coat.
Passivation (ASTM B967-05 )
The passivation process is a method of improving the corrosion resistance of stainless steel parts by removing ferrous contaminants like free iron from stainless steel surface by using Nitric acid or Citric acid. This makes the product less likely to react with air which avoids corrosion and any formation of rust.
Bright nickel plating involves electroplating nickel to produce ductile and bright nickel deposit. It can be applied to a variety of ferrous and non-ferrous metals for a clean and bright finish including steel, copper, brass and iron. It provides corrosion protection with strong wear resistance and an improved appearance.
Alkaline Zinc Plating ( ASTM B633-07 )
Zinc plating is the process of covering metals with a layer or coating of zinc. Alkaline Zinc has a better thickness distribution and ductility. Zinc Plating offers a strong protection against corrosion while also keeping itself in a competitive price range. It’s also a more environmental friendly choice.
Zinc plating is a sacrificial coating that will corrode first before corrosion penetrates and corrode the underlying metal substrate.
