Zinc die-cast alloys are generally non-magnetic. Pure zinc is a non-ferrous metal, meaning it does not contain iron and is not inherently magnetic. Most zinc die-casting alloys, such as the commonly used Zamak alloys (e.g., Zamak 3, Zamak 5), are primarily composed of zinc with small amounts of aluminum, magnesium, and copper. These elements are also non-magnetic, so zinc die-cast parts typically do not exhibit magnetic properties.

Key Points:

Zamak Alloys: The most common zinc die-casting alloys (e.g., Zamak 3: 96% zinc, 4% aluminum) are non-magnetic because they lack iron or other ferromagnetic elements.

Contaminants or Additives: If a zinc die-cast part contains trace amounts of iron or other magnetic materials (e.g., due to contamination or specific alloy formulations), it could exhibit weak magnetic properties, but this is rare and not typical for standard die-casting alloys.

Applications: Zinc die-cast parts are often chosen for their non-magnetic properties in applications like electronics or automotive components where magnetism could interfere with performance.
