MATERIALS · BULK SUPPLY
Powder Supply — For Shops That Run Their Own Machines
If you operate your own SLM or SLS line, the powder is your largest running cost and your most variable input. We supply titanium, stainless steel, aluminium alloy, copper and nylon powders in bulk, sourced from qualified mills with batch documentation traceable to the melt — and we check the export position for your destination before you commit.

OVERVIEW
What we actually supply, and how
We supply the same powders we run on our own lines, in the quantities a production shop or a research group consumes rather than the sachets a hobbyist buys. That covers titanium, stainless steel, aluminium alloy and copper for laser powder-bed metal machines, plus nylon grades for SLS. Each batch comes with a certificate of analysis stating particle size distribution, chemistry and oxygen content, traceable back to the melt it came from — because when a part fails a test, the powder batch is one of the first things you will be asked about.
Traceability is the part that separates industrial supply from "buying powder". A certificate of analysis that cannot be tied to a batch number, a batch that cannot be tied to a mill, and a mill that cannot be tied to a chemistry is not traceability — it is paperwork. We source from qualified mills, keep batch records, and quote the specific batch you will receive so you can put it in your own system before the shipment lands. Where re-use is concerned we will tell you plainly what proportion of virgin powder the material is suited to, and we will not sell recovered powder as virgin.
The commercial reality of metal powder is that it is export-controlled in most jurisdictions, and the rules differ by destination, by grade and by quantity. Rather than discover that at the port, run your destination through our export eligibility checker first. It covers 63 countries and states where a licence is required for each grade. If you need documentation for a licence application we will supply what we can, but we will not ship around a control.
PROPERTIES
How We Supply It
The commercial and logistical terms matter as much as the chemistry when you are buying powder as a production input.
Powder familiesTi-6Al-4V, 316L stainless steel, AlSi10Mg aluminium and copper for metal machines; PA12, PA11, PA12 glass-filled and TPU for SLS.
Particle size distributionMetal powders are supplied in the 15 – 45 µm range that laser powder-bed machines specify. Tell us the machine model and we will confirm the distribution rather than assume a generic one.
DocumentationBatch certificate of analysis covering particle size distribution, chemistry and oxygen content, with the batch number traceable to the melt of origin.
QuantitiesBulk. The right pack size depends on your machine, your build volume and your monthly consumption — tell us those three numbers and we will propose a supply arrangement rather than a one-off shipment.
Batch consistencyWe quote the specific batch you will receive, so you can log it in your own quality system before arrival. Where a repeat order needs a different batch, we tell you in advance, because a chemistry change mid-qualification is a real problem.
Re-use proportionWe will state plainly what proportion of virgin powder a given material is suited to, and we do not sell recovered powder as virgin. If your process relies on a fixed refresh ratio, we will supply to it.
Storage & shelf lifeMetal powders should be kept dry and sealed; moisture and oxidation degrade flowability and raise oxygen content in the built part. We will send the mill’s storage guidance with the certificate.
Export controlsMetal powders are export-controlled in most jurisdictions, with rules that differ by destination, grade and quantity. We check the position for your destination before shipping.
ShippingPowders ship from Guangzhou by air or sea freight depending on quantity and urgency, with customs documentation prepared to match the declared grade.
GRADES & VARIANTS
Powder Families & Grades
These are the powders we keep in supply. Each one corresponds to a material page with the full property data for the parts it makes.
Stainless Steel 316L
METALThe most widely used metal powder we supply, and the most forgiving to run. Chloride- and acid-resistant, ductile and machinable. Full material data.
7.9 g/cm³Marine gradeWeldable
Aluminium AlSi10Mg
METALCasting-grade aluminium developed for laser powder-bed machines. Light, thermally conductive and the easiest of the metal powders to post-process. Full material data.
2.67 g/cm³ThermalMachinable
Copper & Cu Alloys
METALPure copper, CuCrZr and GRCop-42. The most difficult powder to run, because copper reflects almost all of the infrared laser energy, and among the most controlled for export. Full material data.

Powders outside this list — Inconel, CoCr, 17-4PH, specialist polymers — can be quoted on request, subject to export eligibility and mill availability. Ask before you design a process around them.
FINISHING
From Enquiry to Batch
This is what buying powder from us actually looks like, and what we need from you at each step.
Tell us the machine
Model, build volume and layer thickness. Particle size distribution is machine-specific, and this is the single most useful piece of information you can give us.
Tell us the draw
Expected monthly consumption and the refresh ratio your process runs. That determines both the pack size and whether a standing supply arrangement makes more sense than repeat orders.
Check your destination
Run the country of import through the eligibility checker before we quote. Some grades need a licence in some destinations, and knowing early changes the whole timeline.
We quote a specific batch
Not a generic grade — a batch number with its certificate of analysis, so you can qualify it in your own system before it ships.
Documentation goes with it
Certificate of analysis, packing list and customs paperwork prepared to match the declared grade and quantity.
Shipping and tracking
Air or sea freight from Guangzhou depending on volume and urgency, with tracking and customs documentation for the destination.
Repeat orders stay consistent
When a repeat needs a different batch we tell you in advance, because an unannounced chemistry change mid-qualification is a problem you would rather hear about from us.
Technical support
If a powder will not run the way it should in your machine, tell us the parameters and the symptom. We run the same materials and can usually narrow it down.
WHERE IT FITS
Who Buys Powder From Us
Bulk powder is a B2B product with a specific buyer. These are the cases where our supply route is a good fit — and one where it is not.
Strengths
- Five powder families from qualified mills, with batch documentation traceable to the melt
- The same powders we run on our own production lines, so the data behind the material pages is measured on what we sell
- Batch numbers quoted in advance so you can qualify the material in your own quality system
- Straight answers on refresh ratios — we do not sell recovered powder as virgin
- Export eligibility checked per destination before shipping, with assistance on licence documentation
- Machine-specific particle size distribution confirmed against your model rather than assumed
- Consolidated sourcing: powder and printed parts from the same supplier, against the same property data
- Technical support from people who run the same materials daily
Limits to know
- Export controls apply to metal powders in most jurisdictions, and can add lead time or rule a destination out entirely
- Bulk quantities are the point — this is not economic as a route for small or hobby volumes
- Metal powder is a hazardous material for shipping purposes, which constrains air freight and adds documentation
- Batch-to-batch chemistry variation is inherent to powder metallurgy; we manage it by quoting the batch in advance, not by pretending it does not happen
- Powder outside our five families is mill-availability dependent and needs a lead-time conversation
- We will not ship around an export control, and that means some enquiries simply cannot be served
Production shops running SLM lines
A second qualified source for the powder your machines consume, with batch records that fit your quality system. The most common reason clients come to us.
SLS service bureaus
Nylon supply with refresh-ratio guidance, where powder ageing and refresh proportion drive both part quality and running cost.
Research groups and universities
RePEATABLE batches with documented chemistry, which is what makes a result publishable and a comparison meaningful.
R&D departments qualifying a new material
Powder for process development, with the certificate and the batch record you will need when the process is transferred to production.
Companies bringing printing in-house
Powder supply alongside printed reference parts, so you can compare your output against a known-good part in the same material.
Machine integrators and resellers
Consumable supply arrangements for customers who have bought a machine and need a powder source that comes with documentation.

FAQ
Bulk powder — Common Questions
What is the minimum order quantity?
This is a bulk B2B product, so the honest answer is that it depends on the machine and the draw rather than a number we can state in isolation. Tell us the machine model, the build volume and your monthly consumption, and we will propose a pack size and a supply arrangement. If your requirement is genuinely small, we will say so rather than sell you a tonne.
Do I get a certificate of analysis?
Yes, with every batch. It covers particle size distribution, chemistry and oxygen content, and the batch number is traceable back to the melt of origin. When a part fails a test, the powder batch is one of the first things you will be asked about, and a certificate that cannot be tied to a batch number is not much use.
Can you ship metal powder to my country?
Often, but not always, and it depends on the grade as much as the country. Metal powders are export-controlled in most jurisdictions and the rules differ by destination, grade and quantity. Run your destination through our eligibility checker first — it covers 63 countries and will tell you where a licence is required. We will help with documentation, but we will not ship around a control.
Is the powder virgin or recovered?
We sell virgin powder, and where a material is suited to a proportion of recovery we will tell you the working refresh ratio plainly. We do not sell recovered powder as virgin, and we will not quote a refresh ratio we cannot stand behind.
How is the powder shipped?
By air or sea freight from Guangzhou, depending on volume and urgency. Metal powders are classified as hazardous goods for transport, which constrains air freight and adds documentation, so allow for that in your timeline. Customs paperwork is prepared to match the declared grade and quantity.
Can you supply a powder that is not on this list?
Sometimes. Inconel, CoCr, 17-4PH and specialist polymers can be quoted on request, subject to mill availability and export eligibility. The five families listed here are what we keep in supply and run ourselves, so they are the ones we can talk about from direct experience rather than from a datasheet.
