Zinc Alloy Machining: Guide to CNC Processing and Applications

Introduction to Zinc Alloys

Zinc alloys are versatile materials known for their excellent castability, corrosion resistance, and cost-effectiveness. They are widely used in automotive, electronics, hardware, and industrial applications due to their superior mechanical properties and ease of processing.

Specific Types of Zinc Alloys (ISO Standards)

Zinc alloys are classified based on their composition and performance characteristics. Common ISO-standard zinc alloys include:

Zamak Series (Zamak 2, 3, 5, 7): High strength, excellent castability, and corrosion resistance, used in die casting.
ZA Alloys (ZA-8, ZA-12, ZA-27): Higher aluminum content for improved strength and wear resistance.
Zinc-Copper-Titanium Alloys: Used in precision components with excellent dimensional stability.
