  • Aluminium
    • Corrosion resistance of aluminium alloys maybe enhanced by chemical passivation which is to chemically convert the aluminium surface into mixed chromates and oxides in a slightly hydrated form.  This surface coating inhibits corrosion of the aluminium underneath. An aluminium alloy surface maybe chemically converted to provide protection against corrosion where low electrical resistance is required or to provide maximum protection against corrosion. MIL-DTL-5541 is a widely used specification on the requirements for chemical conversion coatings on Aluminium. 

  • Blackening
    • Several metal and metal coatings can be blackened for various applications including corrosion protection, colour coding and thermal properties. The metals that can be readily blackened include aluminium, copper/copper alloys, nickel, steel, stainless steel and zinc..

  • Cadmium
    • Cadmium is a white metal and has excellent corrosion resistance. Cadmium plating is malleable and is more ductile and lubricating than zinc. It provides reliable torquing of plated threads and works well either as a final finish or as a paint base. Pure Cadmium and LHE (Low Hydrogen Embrittlement) Cadmium plating is widely used in aerospace and military applications. A widely referenced standard for Cadmium plating is SAE AMS-QQ-P-416. 

  • Copper
    • Copper is a reddish pink coating that may be deposited as an undercoat or final plate. Copper is a good barrier finish used to secure adhesion between a substrate and the next layer of plating by preventing attack on the substrate and providing a consistency pure interface. Copper plating has exceptional ‘levelling’ power that helps to smooth out or hide surface imperfections and to reduce polishing costs.

      Copper plating requirements may be referenced in accordance with SAE AMS 2418. 

  • Electroless Nickel (EN)
    • Electroless Nickel is a hard Nickel phosphorus alloy of uniform thickness. That means the EN coating thickness on the internal corner of the box shaped object can be the same as the coating thickness found on the external surfaces or sharp points. This coating has very high corrosion resistance and low porosity. The hardness of EN can be increased by heat treatment. EN is deposited without the use of electrical current but by a mechanism called autocatalysis in which Nickel is the catalyst. The abrasion resistance of EN is superior to that of electrolytic Nickel. EN is smooth and reduces galling tendency.

      Some commonly referenced specifications of EN include ASTM B 656, ASTM B733, SAE AMS 2404, SAE AMS 2405, SAE AMS 2405, SAE AMS 26074, ASTM B733, ISO 4527 and MIL-C-26074.

  • Electroless Nickel – PTFE (EN-PTFE)
    • EN-PTFE is a Nickel alloy with PTFE built in to it. EN-PTFE is self-lubricating and coats evenly onto any geometry. EN-PTFE provides the hardness and uniformity of electroless nickel with the improved lubricity and non-stick properties of Teflon.

      EN-PTFE is also deposited by autocatalytic means.

      EN-PTFE maybe plated in accordance with ASTM B 656, ASTM B733, SAE AMS 2404, SAE AMS 2405, SAE AMS 26074, ASTM B733, ISO 4527 and MIL-C-26074.

NEDOX® resists corrosion, friction, sticking, galling and static build-up as well as provides superior mould release. 

    • Nickel is a very widely used plated metal. Nickel is a white metal characterised by a very faint yellow tint that is not always visible to the naked eye. It is very often used as an undercoat or as a final coat. When used as an undercoat, it enhances adhesion and acts as a barrier between the substrate and the next layer of coating. Nickel plating can be ductile and hard and gives improved wear resistance on softer metals such as copper and aluminium. Nickel plating can hide minor surface defects by a mechanism known as levelling. Nickel has good corrosion resistance and is mildly magnetic. 

    • Ductile Nickel: is a modified nickel coating that has an aesthetically pleasing sheen yet is more ductile than any other types of electroplated nickel coatings. Despite its uniqueness, ductile nickel plating requirements maybe specified in accordance with AS 1192, BS 1244, BS 12540, DEF STAN 03-10, DIN 50968, MIL-STD-868 and SAE QQ-N-290
