Frequently Asked Questions
When is zinc preferable to aluminum?
Zinc suits small, detailed parts requiring thin walls, dimensional stability and high-quality plated finishes. Weight and material cost must still be considered.
Can zinc castings be plated?
Yes. Nickel, chrome and other systems are common, but pretreatment, thickness, rack marks and cosmetic zones should be defined before quotation.
