Why Think Zinc? The following characteristics contribute to the integrity of the part, making for a better part overall.
Thinner Walls, Stronger Parts
Zinc alloys are stronger per weight than other materials. This means zinc castings may be produced with thin walls and less material and still be designed to optimize strength in ways other materials cannot. Aluminum’s cost per pound may appear less, but aluminum castings require more material and cost for the same strength.
Tighter Tolerances, Less Machining
Zinc alloys allow us to produce parts with tighter tolerances than aluminum or plastic. Zinc’s precision is better than other materials, which allows us to design features that do not require more expensive machining that other materials require.
Zinc alloys have high fluidity when the alloy is molten. This produces a resilient casting with greater impact resistance and rigidity than its plastic and aluminum counterparts.
The surface of a zinc casting allows for great adhesion of many finishes to its surface, from powder coatings to plated finishes.
The variety of zinc alloys allow us to maximize strength, rigidity, or fluidity in our castings.
All in all, these characteristics allow us to make a better part with zinc than we could with other materials.
