Zinc Alloy Plating Solutions

Zinc Alloy Plating can mean the use of Tin Zinc, Zinc Iron or Zinc Nickel.

Tin Zinc Plating for corrosion protection

Tin Zinc plating provides an extremely lubricious film with exceptionally good throwing power and exhibits exceptional corrosion resistance.

The alloy of Tin and Zinc in the plated layer also provides galvanic corrosion protection of steel substrates when they are in contact with aluminium.

The plated film is conductive and offers solderability where required.

It is also incredibly ductile and components can be post formed by crimping and bending after plating.

Tin zinc is an ideal replacement for cadmium plating whilst not suffering from the harmful environmental impacts.

Key Properties

• Corrosion Protection
• Typical Rack plated component with yellow passivate - 2000+ hours to Red corrosion (neutral salt spray)
• Ductile
• Temperature resistant
• Conductive
• Solderable
• Lubricious

Zinc Iron Plating for corrosion resistance

Zinc iron plating offers good corrosion resistance, typically 4 to 5 times better performance than Zinc plating and a deep, lustrous black appearance.

It is used extensively in applications where its appearance is of key importance.

Key Properties

• Corrosion Protection
• Typical Rack plated component with black passivate - 480 hours to White corrosion
• Consistent Black finish
• Abrasion resistance - harder than normal Zinc plating systems
  
  

Zinc Nickel Plating as an anti corrosion solution

Zinc nickel plating has the ability to offer outstanding corrosion protection, especially when subjected to high temperatures. It is used extensively in automotive under bonnet applications where its temperature and corrosion resistance are vital.

Zinc Nickel is used to plate steel components when they are to be assembled with other dissimilar metals, particularly aluminium, and where there is a greater risk of galvanic corrosion. The plating layer is extremely ductile which enables pipe and tube assemblies to be plated prior to manipulation into their final shape.

Its corrosion protection can be enhanced with clear, yellow or black Trivalent passivates.

Key Properties

• Corrosion Protection
• Typical Rack plated component with colour passivate - 1000 hours to White corrosion, 1500 hours to red corrosion (neutral salt spray)
• Ductility
• Temperature Resistance
• Abrasion resistance - harder than normal Zinc plating systems
