USPS Standard Cast Aluminum Mailbox Specifications

A cast aluminum mailbox is not automatically USPS approved. For curbside mail delivery, the complete mailbox designâ??not only its material or external dimensionsâ??must comply with USPS-STD-7C and receive approval before a manufacturer can use markings such as â??Approved By The Postmaster Generalâ?� or â??USPS-Approved.â?�

Cast aluminum and wrought aluminum

https://www.ljmetals.com/company-news/cast-aluminum-vs-wrought-aluminum-fence.html

Cast aluminum and wrought aluminum perform different functions in a commercial fence system. Cast aluminum is produced by pouring molten alloy into a mold, making it suitable for decorative panels, finials, post caps, medallions, bases and complex architectural shapes.

Wrought aluminum refers to aluminum processed into extruded, rolled or fabricated sections. In fencing, it is commonly used for rails, pickets, posts and standardized structural panels. The Aluminum Association maintains separate technical data and standards for cast products and wrought aluminum products because their production methods, tolerances and mechanical properties differ.

ZAMAK is a family of zinc-based casting alloys containing aluminum, magnesium, and copper. The name is derived from the initial letters of the main components: Zinc, Aluminum, Magnesium, and Kupfer (copper).
ZAMAK alloys are characterized by high fluidity, casting precision, good strength, and a high-quality surface finish. They are particularly well-suited for the mass production of complex parts using die casting.
