Aluminum Zirconium Master Alloy

Aluminum Zirconium Master Alloy is a binary master alloy with aluminum (Al) as the matrix and zirconium (Zr) as the primary alloying element. Available in Zr5 and Zr10 grades with zirconium contents of 5% and 10% respectively. Supplied in two forms: waffle ingot and CCB — waffle ingots suit manual batch addition with standardized weight; CCB can be added online via automatic feeders on continuous casting-rolling lines or cut as needed. Feed rate is adjustable according to requirement; its core function is grain refinement and improving strength (Grain refinement, improve strength).

[Key Advantages]
· Zr5 (5%) and Zr10 (10%) grades for flexible selection based on target alloy zirconium content requirements; feed rate adjustable according to requirement.
· Zirconium forms dispersed Al₃Zr particles in aluminum alloys, effectively inhibiting grain growth and recrystallization, significantly refining grains, and improving strength, thermal stability, and creep resistance.
· Introducing zirconium via master alloy form offers lower melting temperature than pure zirconium, faster dissolution, and uniform zirconium dispersion, reducing segregation risk and ensuring batch-to-batch composition consistency.
· Waffle ingot form suits batch addition; CCB form enables online stable addition via continuous casting-rolling automatic feeders or flexible cutting as needed; both forms are convenient for storage and transportation.
· Uniform and stable composition; both forms cover multiple production scenarios from batch smelting to continuous casting-rolling.

[Product Uses]
· Core application: grain refinement, improve strength; feed rate according to requirement — mainly used in aluminum alloy production requiring zirconium microalloying to enhance strength, thermal stability, and anti-recrystallization capability.
· Widely applied in 7xxx high-strength aluminum alloys (e.g., 7075, 7050) and aerospace aluminum alloy smelting batching; zirconium refinement and recrystallization inhibition improve strength, toughness, and thermal stability, meeting stringent aerospace structural component performance requirements.
· Suitable for aluminum alloy continuous casting-rolling production; CCB form added online for continuous stable zirconium content control; widely used in high-strength aluminum plate/strip and profiles requiring good formability.
· Can be used in electronic heat dissipation alloys, rail transit aluminum components, and high-end consumer electronics casing alloys, improving comprehensive mechanical properties and service reliability through zirconium microalloying.
