Alloys and Manufacturing Technologies from Phyllis Lucius's blog

In general, about half of the zinc consumed finds its way into galvanizing steel, where it serves to prevent corrosion. Zinc is also used as an oxide in a variety of industries, including the chemical, pharmaceutical, cosmetics, paint, rubber, and agricultural industries. The market offers a variety of wrought alloys in the form of flat-rolled, wire-drawn, extruded, and forged products, as well as products made from other metals. Their use in the construction industry includes the production of roofing, downspouts, gutters, flashlight reflectors, lamp parts, and other related materials and products.

The second section is titled "Alloys and Manufacturing Technologies."

Zinc alloys that are commonly available on the market can be manufactured using a variety of processes, depending on the amount of alloying elements present. These processes include hot chamber die-casting, cold chamber die-casting, gravity and sand casting, as well as spin casting and slush casting.

A permanent die is used to cast metal parts, and the molten metal is injected into the die under high pressure and at high speed. Thus, die casting aluminum is possible to obtain castings with nearly net shape, which are characterized by thin sections, tight dimensional tolerances, smooth surfaces, high production rates, and other characteristics. When using the hot-chamber process, for example, the injection system (which includes a pump die casting aluminum supplies heated channel known as the gooseneck) is submerged into the crucible holding the hot-chamber alloy mixture. Because of their low melting temperature, zinc alloys are typically processed using the hot-chamber die-casting technique, which accounts for approximately 90–95% of all zinc alloys. This is due to the associated increase in their melting temperatures and their tendency to attack, react with, or dissolve the injection system.

Spin casting is a method of filling a rubber mold that makes use of centrifugal force.

As previously stated, zinc casting alloys always contain aluminum as the primary alloying element in their composition.
They are the most widely used in industrial applications because they correspond to the hot-camber die-casting alloys, which are commonly referred to as Zamak in the industry. The hyper-eutectic/eutectoid alloys are more devoted to cold chamber process or gravity and sand casting, and they serve a more limited market segment than the others.
