Zamak 5 Zinc Alloy: The Higher Strength Choice for Die Casting Applications on Alibaba.com

Understanding Zamak 5: Composition and Mechanical Properties

When Southeast Asian manufacturers consider selling zinc die casting products on Alibaba.com, understanding material specifications becomes critical for matching buyer requirements. Zamak 5 (also known as ZL0410 in European standards) represents one of the most widely used zinc alloys in the die casting industry, distinguished by its enhanced copper content that delivers measurable performance advantages over the more common Zamak 3.

Zamak 5 Chemical Composition: Aluminum 3.5-4.3%, Copper 0.75-1.25%, Magnesium 0.03-0.08%, with the remainder being zinc. The copper content is the defining difference from Zamak 3, which contains less than 0.03% copper ^[1]^[2]^[3].

The addition of copper fundamentally alters the alloy's mechanical behavior. According to comprehensive materials testing data, Zamak 5 achieves a tensile strength of 331 MPa and yield strength of 295 MPa, representing approximately 10% improvement over Zamak 3's 283 MPa tensile strength ^[1]^[3]. This strength enhancement comes with trade-offs: Zamak 5 exhibits reduced ductility with elongation at break ranging from 2% to 7%, compared to Zamak 3's 10% elongation ^[3].

Zamak 5 vs Zamak 3: Mechanical Properties Comparison
