Niobium plates provide cold-rolled and chemically cleaned surfaces. Due to its strength and workability, very thin niobium plates can be coated on other surfaces, providing excellent corrosion protection and cost-effectiveness. According to your specifications and requirements, all our niobium plates and plates have been visually inspected, and only after removing the stains, wrinkles, and excessive rolling marks on the surface of the plates, will they be shipped.
