How Indian Foundries Optimize Secondary Aluminium Feedstocks for Quality Castings
Optimizing melt chemistry, balancing ADC12/LM6 silicon ratios, and reducing dross formation when using imported scrap feedstocks.

Secondary aluminium casting is the backbone of India's automotive component supply chain. High-pressure die-casters producing engine brackets, transmission cases, and pump housings rely primarily on secondary aluminium ingots conforming to specifications such as ADC12 (Al-Si9Cu3) and LM6 (Al-Si12).
Balancing the Charge with Scrap Feedstocks
Formulating a high-recovery charge requires strategic pairing of scrap varieties:
- Base Alloy Feeder: Sourcing Aluminium Auto Purja Scrap provides pre-alloyed automotive cast metal with baseline silicon and copper content, reducing the need for expensive master alloy additions.
- Low-Magnesium Dilution: Utilizing clean Aluminium Bartan Scrap introduces high-purity aluminium that allows metallurgists to control magnesium thresholds without excessive fluxing.
- Dross Reduction Practices: Compacted bales (such as compressed sheet offcuts and baled wire) minimize surface area exposure to oxygen, significantly curbing metal oxidation and melt losses during induction heating.
Partnering with a reliable importer who guarantees batch consistency ensures foundry yield targets are met shift after shift. Explore Clueblu's full materials catalog or contact our technical team for custom supply consultations.
