Although more commonly used in the die casting industry as a high strength, highly cosmetic alloy, ZA-8 is also cast using a gravity fed process known as the Graphite Permanent mold process. It's lower aluminum content allows for the casting to be plated much easier than its ZA-12 or ZA-27 counterpart.
