OPTICAL EMISSION SPECTROMETER LAB

Tested at every stage, not just at the end.

Testing, start to finish: We test at three points, not one: incoming raw material, in-process during melting and refining, and outgoing finished goods. That's what makes our ingot quality possible to promise consistently, not just occasionally.

  • 100% Optical Emission Spectrometer chemical analysis per melt batch.
  • Traceable ingot batch coding & mill test certificates supplied with each load.
FREQUENTLY ASKED QUESTIONS

Quality Control FAQs

Answers to common questions regarding our alloy specifications, testing certificates, and quality standards.

How does Silverton ensure 100% chemical composition accuracy?
Every heat melt batch is tested twice using our Optical Emission Spectrometer (OES) — once during the liquid refining stage in the furnace, and once after ingot casting. Test certificates detailing exact element percentages (Si, Fe, Cu, Mn, Mg, Zn, Ti, etc.) are issued for every shipment load.
Can Silverton manufacture custom tailor-made alloy compositions?
Yes! Silverton offers tailor-made chemical compositions tailored to customer-specific automotive wheel and piston casting tolerances, conforming to JIS, BS, EN, ASTM, or customized specs.
