Your Partner Every Step of the Way

Strict Quality Control

From inspecting raw materials to control testing and sampling as the alloy progresses to the final pour, we monitor ingot quality at every stage. All samples are analyzed per A.S.T.M. specifications and calibration standards are traceable to N.I.S.T. Two laboratories – one in production and one main lab – are equipped with three atomic emission spectrometers to ensure consistent quality.

Custom Tailored Scrap Handling Service

Our fleet is fully equipped to handle your generation of scrap metal. From small in-plant containers to large roll-off bins, we will custom tailor a scrap handling system to best fit your needs. On top of purchasing your scrap metal, we also offer a tolling service to convert your scrap back into specification alloy ingot.

Operating our own fleet, we offer next-day delivery West of the Rockies. Whether you require just-in-time deliveries – or need us to work out a regularly scheduled shipment – a Custom Alloy truck will be there when you need it.
