Component Specifications

Definition
A specialized metallurgical component consisting of high-purity zinc combined with controlled trace elements, designed for precise addition to copper melts to create copper-zinc master alloys. This element enables controlled zinc content adjustment in final alloys, ensuring consistent composition for applications requiring specific mechanical, electrical, or corrosion-resistant properties.
Working Principle
Works through controlled dissolution and diffusion mechanisms when added to molten copper. The zinc element dissolves uniformly in the copper matrix, forming solid solutions that modify crystal structure, grain boundaries, and phase distribution. This alters electrical conductivity, tensile strength, hardness, and corrosion resistance through metallurgical bonding at atomic level.
Materials
High-purity zinc (99.99% Zn minimum) with controlled additions of aluminum (0.01-0.05%), magnesium (0.005-0.02%), and titanium (0.001-0.01%) as grain refiners. Trace elements limited to: Pb<0.003%, Cd<0.002%, Fe<0.005%, Sn<0.001%.
