Fayyadama MRI keessatti, qaamoleen dirree maagneetii akka hin jallisnee fi bakka kutaaleen gara maagneetiitti harkifaman 'bu'aa piroojektiilii' ittisuuf maagneetii hin taane ta'uu qabu. Standard carbon steels and 400-series stainless steels are ferromagnetic and unsuitable. 316 Stainless Steel is generally non-magnetic (permeability $\mu < 1.01$), but cold-working can induce magnetism through martensite formation. Therefore, for 'Zero-Magnetic' requirements, materials like Beryllium Copper (CuBe) or MP35N are preferred. CuBe (alloy 25) offers excellent spring properties and remains completely non-magnetic regardless of cold work or heat treatment, making it the industry standard for MRI-compatible wave springs.
