Shanghai United Metal Materials supplies a portfolio of permanent and soft magnetic materials based on mixed magnetic alloys including sintered and bonded NdFeB, hard ferrite (strontium and barium variants), SmCo in 1:5 and 2:17 grades, cast and sintered AlNiCo, rubber-bonded magnet composites, and soft ferrite cores in Mn-Zn and Ni-Zn compositions. The materials are offered in custom dimensions with surface treatments that include nickel, zinc, chromium, and copper plating, epoxy resin coating, and spray-applied epoxy resin finishes. Grades, dimensions, and plating configurations are configurable to buyer specifications for motor, sensor, speaker, MRI, and industrial holding applications.

NdFeB grades cover both isotropic bonded and anisotropic sintered forms, with typical remanence (Br) ranging from 0.6 T to 1.4 T depending on grade and processing route. Hard ferrite magnets deliver moderate energy product with high coercivity and excellent corrosion resistance without plating; typical (BH)max values span 1.0 to 4.5 MGOe. SmCo 1:5 and 2:17 grades offer temperature stability up to 250-350 degrees Celsius with high corrosion resistance, making them suitable for aerospace and military applications. AlNiCo cast and sintered variants provide high Curie temperature and low temperature coefficient, with typical coercivity in the range of 400-1600 Oe. Soft ferrite Mn-Zn cores exhibit high permeability and low core loss at frequencies below 1 MHz, while Ni-Zn variants suit higher frequency applications above 1 MHz due to higher resistivity.

These magnetic components are procured by manufacturers of brushless DC motors, automotive sensors, loudspeaker drivers, magnetic resonance imaging systems, magnetic separators, and precision holding fixtures. Buyers typically specify dimensional tolerances Mustang-Gauge drawing, required flux density at working temperature, plating salt-spray requirements (standard: 48-96 hours per ASTM B117), and magnetization pattern (axial, radial, or multipole). Shanghai United Metal Materials accepts custom grade and geometry requests; buyers should confirm MOQ, sample lead time, and whether the supplier holds IATF 16949 or ISO 9001 certification for automotive or medical supply chains.

Shanghai United Metal Materials is headquartered at Shangkai Building, No.1209 Kunming Road, Shanghai 200092, positioning the company within China's principal industrial and logistics corridor for magnetic materials export. The supplier is classified at harbor trust tier, which indicates baseline marketplace presence without advanced verification signals. The response rate is recorded at 0.00 percent with zero average response hours, meaning prospective buyers should anticipate delayed or inconsistent communication and should plan sourcing timelines accordingly. The listing presents a broad materials portfolio rather than a narrow speciality, suggesting the company operates as a materials trader or distributor with access to multiple manufacturing lines rather than a single-facility producer.

The company profile does not disclose manufacturing certifications, annual output figures, workforce size, or specific clientele, so buyers cannot independently verify production scale or quality management systems from this listing alone. The address in Shanghai's Yangpu district places operations near port infrastructure (Shanghai Port / Yangshan), which offers logistical advantage for FOB or CIF shipments, though buyers must confirm Incoterms, packing standards, and export documentation capability directly with the supplier. No information is provided about in-house magnetizing equipment, dimensional inspection capability, or magnetic property testing (hysteresisgraph, fluxmeter, Helmholtz coil), so buyers requiring certificated test reports should request third-party or in-house test data before committing to volume orders.
