Product Description
CuZr40 Copper Zirconium Master Alloy 40 Percent Zr Grain Refiner for High Strength 7xxx Series Aluminum Alloys
CuZr40 Copper Zirconium Master Alloy – 40% Zr Grain Refiner
This CuZr40 master alloy is a specialized zirconium additive designed for precise grain refinement in high-performance aluminum alloys, particularly the 7xxx series (Al-Zn-Mg-Cu) used in aerospace structural applications. The copper-based carrier ensures rapid dissolution and uniform zirconium distribution in the aluminum melt.
Key Metallurgical Functions
- Al3Zr Dispersoid Formation: Zirconium reacts with aluminum to form coherent L12-structured Al3Zr dispersoids during homogenization, effectively pinning grain boundaries and suppressing recrystallization during hot working and solution heat treatment
- Grain Structure Control: Provides uniform fine equiaxed grain structure in cast and wrought products, improving mechanical isotropy and reducing anisotropy in rolled plates and forgings
- Stress Corrosion Resistance: Finer grain structure combined with dispersoid distribution significantly enhances stress corrosion cracking resistance in aggressive environments
- Superplastic Forming Enablement: Stabilized fine grain structure permits superplastic forming of complex aerospace components at elevated temperatures
Market Applications
| Industry | Alloy Systems | Component Examples |
|---|---|---|
| Aerospace | 7050, 7055, 7085, 7449 | Wing spars, fuselage frames, bulkheads |
| Defense | 7039, 7017 | Armor plate, missile components |
| Automotive | 7xxx casting alloys | Lightweight chassis, EV battery trays |
Quality Assurance
