Description

Sold by the box.

This ingot measures approximately 1.75" x 7/8" x 4.25" and weighs 1-1.1 
pounds

This is a pre packed box if 12 ingots   you will get 12-13 pounds total 

 

ZA-12 is the most versatile zinc alloy in terms of combining high performance properties and ease of fabrication using either gravity or pressure die casting. ZA-12 is the best gravity casting alloy for sand, permanent mold and the new graphite mold casting process. It is also a good pressure die casting alloy (cold chamber) which provides a sounder structure than ZA-27, as well as higher die cast elongation and impact properties. For these reasons, die cast ZA-12 often competes with ZA-27 for strength application. An excellent bearing alloy, ZA-12 is also plateable, although plating adhesion is reduced compared to the ZAMAK alloys.

ZA-12 alloy is an excellent combination of mechanical properties and casting ability. Due to its elevated aluminum content, this alloy is cast in a cold chamber die casting machine.

ZA-12 advantages - not sensitive to cooling rate, great machinability (stress relieving temperature - 212 degrees F for 3-6 hours, air cool), great reproduction of pattern detail due to better castability, palatability is similar to zinc die cast parts, lower material costs & casting temperatures versus copper alloys, also used to create prototype/short run parts that can be die casted, has the corrosion resistance of zinc die castings.

Casting - does not separate readily; use a gating/riser system (such as used for red basses or aluminum alloys).  Surface shrinkage occurs on the underside (not upper).

Melting - to be done quickly.  Pouring temperature - below 930 degrees F.

    A repeat purchase for me, a great alloy in a great size for the foundry hobbyist.

    Excellent for casting and the smaller ingots are great for the "weekend warrior" with a small furnace.

    Great option for smaller castings

    Posted by Frederick William Pletz on Mar 30th 2024

    This is a great option for smaller castings. I wish they were slightly skinnier as this just barely fits in the small crucible I have - but it's easier to trim the edges of this than trying to cut the larger bars down to size. Would love to see this available in chunks like what brass comes in.
