Aluminum Alloying Element: Thermal Conductivity 120-240 W/m·K

Component Specifications

Definition

Aluminum alloying elements are specific metallic substances intentionally added to aluminum during the production of zinc-aluminum master alloys to achieve desired metallurgical characteristics. These elements alter the microstructure, mechanical properties, corrosion resistance, and processing behavior of the final alloy. In industrial-grade high-purity zinc-aluminum master alloys, these elements are precisely controlled to ensure consistent performance in applications requiring specific strength, ductility, or thermal properties.

Working Principle

Aluminum alloying elements work by dissolving into the aluminum matrix or forming intermetallic compounds that modify the crystal structure. This alters dislocation movement, grain boundary characteristics, and phase distribution, resulting in improved mechanical properties, enhanced corrosion resistance, or modified thermal expansion coefficients compared to pure aluminum.

Materials

High-purity aluminum (99.7%+ Al) with controlled additions of alloying elements such as copper, magnesium, silicon, manganese, or zinc. Trace elements like iron, titanium, or chromium may be present within specified limits.
