Silicio 5505
Industrial grade with excellent value. Ideal for secondary casting alloys where maximum purity is not critical. Special pricing available.
Silicon 5505 is an industrial grade widely used in secondary aluminum casting. Its impurity limits (Fe ≤ 0.5 %, Al ≤ 0.5 %, Ca ≤ 0.05 %) make it suitable for most general-purpose AlSi alloys like 380, 383, and A413 where recovered aluminum is the base material. The nomenclature indicates maximum allowed levels: 55 = 0.5 % Fe + 0.5 % Al, 05 = 0.05 % Ca. We offer this grade with very competitive pricing and immediate availability.

Metallurgical Function
Raise silicon content in Al-Si alloys to improve fluidity, reduce solidification shrinkage, and increase wear resistance.
Dosage & Usage
Variable depending on target alloy. To bring a secondary aluminum base to AlSi7 requires approximately 6–8 % addition. For AlSi11 (413), approximately 10–12 %. Add directly to molten bath and stir for complete dissolution.
Applications
- AlSi casting alloys (356, 360, 380, 383, 413)
- 6xxx series extrusion alloys
- Secondary aluminum casting
- Al-Si master alloy production
