Technically Advanced Metal Powders

“Goodwin are investing in new facilities in support of global Additive Manufacturing markets to produce customized, high quality metal AM powders of grades that have already been established, as well as creating new, highly specialized powders developed in cooperation with our customers for critical duty applications”

We offer optimised spherical metal powders specific to AM machines including EOS, SLM Solutions, Concept Laser, Renishaw, 3D Systems, Trumpf, and Arcam 3D metal printers. Our metallurgists have the expertise to carefully characterize AM alloys to your specification. Important parameters such as the morphology of powder particles (slope and freedom from satellite particles), selection and reproducibility of powder size distributions and particle surface characteristics dictated by optical emissivity oxide levels, moisture and electrostatic charges are considered during manufacture.

The majority of alloys supplied are to ASTM standards and can also be provided in accordance with other regional standards such as the European EN standards. All powders supplied are fully traceable with certification providing assurances that the product acceptance specification has been achieved. We supply small volumes to facilitate R&D projects, prototyping and specialist requirements. Long-term supply agreements are available for larger volumes

Remelt Stock

Goodwin achieves technically challenging target chemistries to maximise the return for the customer as a result of the breadth of knowledge and skillset retained within the melt shop. A bespoke software system is employed to ensure traceability of material throughout the process in which yield analysis can be performed for each out turn of consolidated or refined feedstock.

We supply air melted ingots to the investment casting industry and industrial melt shops who value known analysis charge material. The minimum consolidation melting charge is 500Kg of material. The minimum refining charge is 8000Kg of material. Goodwin offer re-melting stock in the form of 20Kg pigs or standardised cast billets from 500-5000Kg. Material is securely palletised and shrink wrap covers applied to prevent the ingress of water and aid material identification of saleable feedstock.

With the increasing popularity of the austenitic, super austenitic and duplex stainless steels melt shop face an increasing need to ensure the economic supply of quality feed stock and also the control their melting returns. Many end users and specifiers including BP, Statoil, Norsok, the NACE technical committee and CTi recognise the value and importance of using refined melting stock and the use of refined material is mandatory for some petrochemical contracts.
