1.As-Cast
Zinc and zinc-aluminum parts can be left as-cast and retain reasonable corrosion resistance. Aluminum and magnesium parts must be 

coated to achieve corrosion resistance.Cast parts are typically broken away from the casting

sprue, leaving rough marks at the gate locations. Most castings will also have visible marks 

left by the ejector pins.Surface finish for as-cast zinc alloys is commonly 16-64 microinch Ra.



2.Anodizing (Type II Or Type III)Aluminum is typically anodized. 

Type II anodizing creates a corrosion-resistant oxide finish. Parts can 

be anodized in different colors—clear, black, red and gold are most 

common. Type III is a thicker finish and creates a wear-resistant layer

 in addition to the corrosion resistance seen with Type II. Anodized coatings

 are not electrically conductive.


3.Powder Coating
All die cast parts can be powder coated. This is a process

where powdered paint is electrostatically sprayed onto a part which is then 

baked in an oven. This creates a strong, wear- and corrosion resistant layer that is more durable than standard wet painting methods. 

A wide variety of colors are available to create the desired aesthetic.


4.Plating
Zinc and magnesium parts can be plated with electroless 

nickel, nickel, brass, tin, chrome, chromate, Teflon, silver and gold.


5.Chemical Film
A chromate conversion coat can be applied to protect aluminum 

and magnesium from corrosion and improve the adhesion of 

paints and primers. Chemical film conversion coatings are electrically conductive.
