Industrial applications often involve vibration, impact, and mechanical stress that can fracture standard magnets. Our industrial strength magnets are engineered with enhanced fracture toughness through optimized microstructure control and strategic material additives. We conduct comprehensive mechanical testing including drop tests from 1.5 meters, vibration testing per MIL-STD-167, and compressive strength verification to ensure survival in demanding industrial environments.

Product Description
Industrial Strength Magnets: Engineered for Demanding Manufacturing & Processing Applications
Industrial Performance Characteristics
Mechanical Durability & Shock Resistance
Extended Temperature Performance Range
Industrial equipment frequently operates at elevated temperatures. Our specialized material formulations provide working temperature ranges from -50°C to +600°C depending on material type. For neodymium magnets, we offer EH and AH grades with temperature coefficients as low as -0.07%/°C, while our samarium cobalt magnets maintain performance up to 350°C and alnico magnets to 600°C, ensuring reliable operation in ovens, motors, and thermal processing equipment.
Corrosion Protection for Industrial Environments
Industrial settings often expose magnets to moisture, chemicals, and corrosive atmospheres. Our standard Ni-Cu-Ni triple-layer electroplating (minimum 15μm total thickness) provides 500+ hours of neutral salt spray protection per ASTM B117. For extreme conditions, we offer epoxy coatings, gold plating, or specialized passivation treatments that withstand aggressive industrial chemicals while maintaining dimensional stability of the industrial strength magnets.

| Ferrite (Sr/Ba) | 250°C | Excellent | 0.2-0.4 T | 120-300 kA/m | Brittle | Low-cost motors, holding applications |
Quality Assurance for Industrial Applications
Every batch of industrial strength magnets undergoes our 12-point quality verification protocol specifically designed for industrial applications. This includes dimensional verification with coordinate measuring machines (CMM), magnetic performance testing at both room temperature and elevated temperatures, coating thickness verification using X-ray fluorescence, salt spray testing per ASTM B117, mechanical shock testing, and thermal cycling between -40°C and maximum operating temperature. Our IATF 16949 certification ensures automotive-grade quality management, while ISO 9001:2015 provides the framework for consistent manufacturing processes.
IATF 16949:2016 ISO 9001:2015 ASTM B117 Salt Spray Tested Thermal Cycling Certified Mechanical Shock Tested REACH & RoHS Compliant
Industrial Packaging & Logistics
Recognizing that industrial magnets often ship directly to manufacturing facilities, we employ industrial-grade packaging solutions. Each magnet is individually separated in 8-cell reinforced inner packaging with non-magnetic spacers, then packed in heavy-duty export cartons or wooden crates with corner protection. Our packaging is validated to withstand transit vibration per ISTA 3A standards and includes clear labeling with handling warnings, magnetic strength indicators, and material safety data sheets when required.
