zinc alloy

Steel and iron components are zinc plated to provide improved corrosion resistance. The protection is largely the result of the zinc deposit acting as an anode to the base metal.

Alloying metals such as aluminum, iron and nickel with the zinc plate significantly improves this corrosion resistance.

The most common zinc alloys can be summarized;

 

  • Enviralloy Ni (alkaline) and Kenlevel Ni (acid) zinc-nickel systems are the most popular, particularly for automotive
    applications.
  • Zinc-iron is an economical deposit offering improved corrosion protection compared to zinc plate. Enviralloy Fe (alkaline) has been used for many years to provide a high quality black finish with exceptional deposit
    distribution for both fasteners and fluid transfer tubes.
  • AlMac (mechanical) zinc-aluminum* is extensively used in rivet fastening applications for light metals such as
    aluminum sheet.
  • Enviralloy SN tin-zinc finds use for fluid transfer tubes and fasteners in contact with aluminum respectively.

 properties of zinc

properties of zinc metal

Zinc is a bluish-white, hard and crystalline transition metal which is electronegative to iron and gives excellent corrosion resistance, particularly in industrial and urban environments.

It is used extensively to protect ferrous metals and the properties of zinc metal mean that it can applied by hot dip galvanizing, electrodeposition or mechanical plating.


The Standard atomic weight of zinc metal is 65.38 and has a density of 7.14 g·cm−3. Zinc's melting point is 419.5°C and it has a boiling point 907 °C.
