At EPI Materials, our tantalum sheet and plate production process embodies a meticulous journey from sourcing raw materials to delivering finished products of unmatched quality. Here is a detailed walkthrough of our tantalum sheet/plate workflow:

  • Raw Material Procurement
    • Sourcing: EPI Materials ensures the procurement of raw tantalum of the highest purity (99.95%), primarily from conflict-free zones, aligning with the RMAP compliance.
  • Powder Metallurgy
    • Powder Production: Utilizing advanced technologies, we convert raw tantalum into fine powder form, maintaining a keen focus on achieving uniform particle size and purity.
  • Sheet/Plate Formation
    • Compaction: The tantalum powder undergoes a compaction process where it is shaped into preliminary sheets or plates under high-pressure conditions.
    • Sintering: The compacted material is then sintered at temperatures exceeding 2000 °C, which facilitates the development of the desired microstructure and density.
  • Mechanical Processing
    • Rolling: Post-sintering, the material is rolled to achieve the final thickness, adhering to precise tolerances that meet or exceed industry standards.
    • Using precision equipment, the sheets and plates are cut into standardized or custom sizes as per client specifications.
  • Quality Assurance
    • Testing: Each batch undergoes stringent testing to verify conformity with ASTM B708 and ASTM F560 standards, ensuring the mechanical and chemical properties are up to the mark.
    • Certification: A certificate of quality is generated, detailing the compliance of the product with established standards and verifying the purity levels.
  • Packaging and Delivery
    • Packaging: The finished sheets and plates are carefully packaged to prevent any damage or contamination during transit.
    • Delivery: Ensuring timely delivery, we ship the products to the client’s location, adhering to the agreed timelines.
  • Customer Service
    • Support: Our team remains available for any post-sales support, addressing any concerns or queries that might arise.
