Define the part’s function
Light weight, corrosion resistance, temperature resistance, conductivity or tool life do not point to the same material. Write down the part’s environment, load, operating temperature and failure criterion. Deciding on price per kilogram alone before these needs are covered is not the right approach.
Check machine and process compatibility
LPBF, DED, binder jetting and MIM require different powder properties. The same chemical alloy may be available with different particle size distributions or morphology. Match the machine model, energy source, feed method and approved powder range against the manufacturer’s documents.
Define the end user’s documentation needs
Request the manufacturer datasheet, batch certificate of analysis (CoA), safety data sheet (SDS), particle size distribution and flow measurement method. For a critical part, define test specimens, build orientation and the heat treatment plan before ordering.
What to include in your quote request
Always share the alloy or performance target, process, machine, particle size cut, trial/series quantity and delivery location. If the material is not yet defined, describe the application and ask for a technical comparison of candidate materials.
Catalogue data is a reference for material selection; the datasheet, certificate of analysis of the delivered batch and application tests prevail.
