100% SPECTROGRAPHIC CHEMICAL CERTIFICATION

Every Melt Charge Tested Prior to Dosing

We operate on-site Optical Emission Spectrometers (OES). Prior to tapping molten aluminium into holding furnaces, chemical composition—including Silicon (Si), Copper (Cu), Magnesium (Mg), Iron (Fe), and trace elements—is verified against customer master standards. Full Mill Test Certificates (MTRs) accompany every shipment.
