High-Purity Aluminium Strontium Master Alloy – Precision Engineered for Superior Performance
Premium-grade AlSr master alloy (AlSr10, AlSr15, AlSr20) with exact strontium composition for consistent grain refinement in aluminum casting. Ultra-low gas content and controlled impurity levels ensure crack-free, high-density aluminum alloys for automotive and aerospace components. Precision-manufactured using vacuum induction melting for uniform strontium dispersion, enhancing fluidity and reducing porosity in die-casting applications. Ideal for foundries producing engine blocks, wheels, and structural parts requiring fatigue-resistant aluminum-silicon alloys. Global bulk supply with factory-direct pricing – optimized for large-scale industrial procurement without quality compromise. Strict ISO-certified production with batch traceability, meeting ASTM B956 standards for master alloy additives.
