美国采购需求：ra铜箔,ra铜箔

I hope this message finds you well. I am reaching out to inquire about your High-precision RA Copper Foil, particularly interested in the thinnest variant. We are currently conducting experiments that require precise materials, and I believe your product could be a strong fit for our needs. To evaluate its suitability, I would greatly appreciate it if you could provide a free sample of the 9 µm option. Should our tests yield promising results, we would be keen to discuss bulk purchasing possibilities with you. Thank you for considering my request, and I look forward to your positive response.
