Zinc Alloys
Zinc alloys include pressure-die-casting, foundry, wrought and rolled products whose creep, aging, dimensional stability and corrosion behavior differ fundamentally from zinc coatings on steel.
Classification basis
Manufacturing route, aluminum level, dimensional/creep duty and finished product form
The directory separates Zamak, higher-aluminum ZA, wrought zinc and sheet/strip procurement while excluding galvanized steel from the base-alloy taxonomy.
A familiar grade name never replaces the governing product specification and certified documentation.01
Explore subcategories
Zamak Die-Casting Alloys
Covers Zamak pressure die castings; excludes ZA foundry alloys and zinc-coated steel.
→ZincZA Casting Alloys
Covers ZA castings and continuous-cast bar; excludes Zamak-only assumptions and wrought sheet.
→ZincWrought Zinc Alloys
Covers mechanically worked zinc and galvanic-anode products where specified; excludes cast Zamak/ZA and coated steel substrate.
→ZincZinc Sheet and Strip
Includes solid rolled zinc products; explicitly excludes zinc-coated or zinc-aluminum-coated steel sheet.
