Special high grade zinc in 2-14 mesh shot and 50 lb slab forms. Used for galvanizing, zinc die casting alloys, brass production, and as a rubber and plastics stabilizer.
Special High Grade Zinc is a high-purity zinc metal supplied in two forms: 2-14 mesh shot for rapid melting additions and controlled alloy compositions, and 50 lb slabs for bulk melting operations. Zinc melts at 787F (419C) and has a density of 0.258 lbs/in3 (7.13 g/cm3). It is one of the most widely used industrial metals, consumed primarily in galvanizing, die casting, and brass production. In galvanizing, zinc is applied as a protective coating to steel by hot dipping or electrogalvanizing to provide cathodic corrosion protection. In die casting, zinc is alloyed with aluminum, magnesium, and copper to produce Zamak and other zinc alloy families used for automotive, electronic, and consumer hardware components. In copper alloy production, zinc is the primary alloying element in brass. Zinc also functions as an aging inhibitor for rubber and plastics. Forms: 2-14 mesh shot and 50 lb slabs.

Frequently Asked Questions
Common technical inquiries regarding Special High Grade Zinc
Hot-dip galvanizing typically uses Special High Grade (SHG) zinc at 99.99% purity minimum to avoid introducing lead, cadmium, and other tramp elements into the galvanizing bath. Zinc die casting alloys also require SHG purity feedstock because even trace levels of lead and cadmium cause intergranular corrosion in zinc die castings over time, a failure mode known as zinc pest.
The 2-14 mesh shot melts rapidly and uniformly in induction and resistance furnaces due to its high surface area-to-volume ratio, making it preferred for alloying operations where quick dissolution and composition control are important. The 50 lb slab is more economical for bulk melting operations such as galvanizing baths and large die casting holding furnaces where melt rate is less critical and handling efficiency favors larger charge units.
Zinc oxide is the primary zinc-based additive used in rubber compounding, where it acts as an activator for sulfur vulcanization and as an aging inhibitor. Zinc oxide reacts with organic accelerators to form zinc complexes that catalyze crosslink formation during vulcanization, producing a more uniform and stable crosslink network. The zinc complexes also stabilize the rubber matrix against thermal and oxidative degradation over time.
