Zamak

Zamak Composition

Zamak is primarily composed of zinc and aluminum, along with other metals. The main components of Zamak 3 are about 96% zinc and a small amount of aluminum. In addition, it contains trace amounts of other metals. The table below lists all the components of Zamak 3:

Advantages of Zamak 3 Alloy

Zamak 3 has become the de facto standard, meaning it is the most widely recognized Zamak on the market. Its advantages include:

• Low melting point and high fluidity, which saves energy during metal part production.
• Excellent castability with high complexity and precision, while maintaining low tolerances.
• Versatile and can undergo various surface treatments such as painting and electroplating.
• Outstanding dimensional stability, contributing to excellent casting performance.
• Recyclable, making it environmentally friendly.
• Excellent vibration damping and shock absorption capabilities.
• High resistance to impact, wear, and corrosion.
• Zamak 3 molds are more durable than aluminum molds, resulting in a longer service life.
• Suitable for both small-scale and large-scale production.
• Does not emit harmful substances that could pollute the air.

Applications of Zamak 3

Zamak 3 is used across many industries to manufacture die-cast components. Some of its most notable applications include:
