Foundry Metallurgy & Chemistry Control

The Metallurgy Department manages alloy chemistry, metallurgical control and casting quality at Knights Foundry's Wadeville, Gauteng foundry. Every melt is analysed and controlled against the customer's specified material requirements before release for pouring.

Optical Emission Spectrometry (OES) is used to verify chemical composition, with chemistry adjusted where required. No melt is released for pouring until the required specification is aligned.
