Zinc Alloys were developed specifically for pressure die casting using hot chamber casting, which is highly automated and the most popular and efficient die casting process. ZA Alloys (Zinc Aluminum Alloys) were developed initially for gravity casting using sand, permanent mold, plaster mold and graphite mold casting techniques. ZA alloys can be used in pressure die casting, but require a cold chamber casting method. Only ZA-8 can be hot chamber die cast.

Hazards Identification

Skin / Eyes

N/A Acute: Contact with zinc powder or dust or zinc oxide fume may cause local irritation.


N/A When excessive zinc or aluminum oxide fumes are inhaled, it may cause flu-like symptoms or fever, chills and nausea.


N/A When ingested in excessive amounts, zinc can irritate the stomach resulting in nausea and vomiting.

Effects of Chronic Exposure to Product

N/A Skin Contact: Prolonged or repeated skin contact with zinc dust powder may cause a mild dermatitis.
