About KBM

KBM Advanced Materials, LLC (“KBM”) is a newly established company formed to finance, sell, and distribute metal powders to the additive manufacturing, MIM, and other advanced manufacturing markets.

KBM bridges the inventory gap between smaller lot customers and larger metal powder producers. Producers can schedule their production equipment to larger regular blanket orders from KBM.  Customers can book jobs, plan R&D and operate their businesses knowing that KBM has in stock their raw material and it is only a day or two away. 

If you are a producer know that KBM sells your product under your brand, preserving your brand recognition and value.   If you are a consumer, know that KBM has in stock the alloy, size fraction AND brand that you need and depend on.

In addition, as a global market leader in metal powder alloys, KBM also provides a valuable e-commerce platform for customers that is not currently available at scale from any producer or supplier.  Digital manufacturing deserves a digital marketplace for physical materials.

Technical and commercial support is provided by The Barnes Global Advisors.
