Intro

Alloys that met at low temperature (431C) [1] and have 60ksi tensile strength. They display the low melting point slightly smaller than that of zinc, with strength significantly greater than that of aluminum (45 ksi). [2].
Majority of composition is Zinc - commonly - 8, 12, 27%
ZA alloys not only show the best melt/strength properties of each component metal. They show IMPROVED melt point (430 compared to 660C for Aluminum) - strength (30% stronger)properties compared to their components.
As such, ZA are magical ingredients for the Desktop Foundry.

Zinc and ZA alloys melt readily at around 420C, as low as 375C - and can possibly be 3D printed through a melting nozzle.
Zinc is also the materials of galvanizing - a critical ingredient of lifetime design with metals.
