Alloy Selection
ADC12 vs LM24: choosing between die casting workhorses
Both are aluminium-silicon-copper die casting alloys with overlapping chemistry, but referencing the wrong standard in an enquiry produces offers that cannot be compared. What to state in a requirement.
ADC12 alloy ingotAlloy Selection
Why LM6 is specified for thin-wall and marine castings
High silicon content gives LM6 fluidity and corrosion resistance at the cost of machinability. Where that trade-off works, and where a copper-bearing alloy is the better commercial answer.

Secondary aluminium and the cost of contamination
Grading, coating residue and mixed alloy streams show up as melt loss and rejection rates. How recycled aluminium requirements should be described commercially.
Recycled aluminiumBillets
6063 or 6082: extrusion billets for architectural and structural work
Surface finish and extrudability against mechanical strength. The billet specification points that most affect extruder productivity.

What a complete aluminium enquiry contains
Grade basis, chemistry tolerance, quantity, packing, destination, delivery period, documentation and inspection. The checklist we work through before approaching producers.

Trading structures in international aluminium supply
Principal trading, indenting representation and sourcing coordination each change who contracts, who invoices and who carries risk. Why the structure is confirmed per transaction.
