Samarium and Gadolinium RFI - Warstopper

Requested Information
     DLA Warstopper Directorate is seeking information for establishing a Samarium and Gadolinium Buffer

Samarium and Gadolinium Information

• Please provide all information on the Samarium and Gadolinium grades and specifications that are used by your company to produce DPAS-rated orders.  Proprietary specification information submitted to the Government will be held as Business Confidential and not disclosed outside of DLA Warstopper or the chain of command responsible for the operation of the Warstopper program. The provider is responsible for identifying proprietary information. Specification information is important as it helps ensure that the materials potentially acquired for the Buffer fit what is needed by the OEMs
  • What exact purity levels (e.g., 99.5%, 99.9% TREM) are required for your Sm and Gd metal inputs?
  • What are your maximum allowable limits for non-rare-earth impurities (specifically Oxygen, Carbon, Iron, and Calcium) in these metals?
  • In what physical form or intermediary state do you procure these materials? (e.g., pure metal ingots, distilled chunks, strip-cast flakes, or pre-alloyed SmCo/SmGdCo powder)?
  • For Gadolinium specifically, what is your typical ratio or blending requirement relative to Samarium for temperature-compensated magnet grades?
  •  What is your current annual volume requirement for both Sm and Gd (or pre-alloyed intermediaries) to support DPAS-rated orders?
  • What is your expected demand for these items over the next five years, factoring in known platform modernization or production increases?
  • What is the current expected lead time for these materials from the time of order placement to delivery at your facility?
  • Do any of these specifications or forms have Minimum Order Quantities (MOQs) or batch-size requirements that affect your ability to produce your products in a timely manner?
  • Do you currently have your own internal buffer of intermediaries?
  • What do you do with any waste produced by the manufacturing process?
  • What specific end-products or platforms do you produce that have known surge requirements which could be affected by increased rare-earth lead times?
  • Are your current sources for Sm and Gd compliant with DFARS 252.225-7052 (Restriction on the Acquisition of Certain Magnets, Tantalum, and Tungsten)?
  • At what tier in your supply chain are the oxide-to-metal reduction and alloying steps occurring?
  • What percentage of the initial Sm/Gd material is lost to manufacturing waste (e.g., swarf, grinding sludge, or off-cuts) during the magnet production and machining process?
  • Do you have an established process or vendor for recycling this manufacturing waste back into usable Sm/Gd intermediaries?

Interested vendors should submit their response as well as any questions through email to the contract specialist, SmCo RFI – Warstopper Christy Boyer at [email protected] with “RFI – SmCo” in the subject line. Responses must be received by 17JULY26 before 3pm EST. It is the vendor’s responsibility to ensure the email was received and is viewable. Verbal questions/responses will not be accepted
