Properties
Manufacturing Process
Step 1
Melting & Refining
High-purity aluminum ingots are melted in a furnace, and the required alloying elements are added to achieve the desired composition. The molten metal is then refined through fluxing, degassing, grain refinement, and ceramic filtration to remove impurities, dissolved gases, and inclusions, ensuring a clean, homogeneous melt ready for casting.
Step 2
Continuous Casting & Rolling (CCR)
Molten metal is cast via a twin-belt caster and immediately hot-rolled in-line (Properzi/CCR process) for energy-efficient rod production.
Step 3
Hot Rolling
A continuous multi-stand rolling mill reduces the rod diameter from the cast cross-section to 6–12 mm in multiple passes at 400–480 °C.
Step 4
Quench & Temper
Water quench immediately after the final roll pass achieves T1 temper, locking in conductivity and providing a clean, bright surface.
Step 5
Coiling
Rod is coiled on a Stelmor-type cooling conveyor; controlled air cooling prevents surface oxidation and ensures uniform temper along the coil length.
Step 6
Inspection & Dispatch
Electrical conductivity (% IACS) measured per coil; surface, dimensional, and tensile tests performed. Coils tagged with full traceability data.
