FAQ
Q1: What key parameters are required for SmCo magnet customization?
A1: To ensure the accuracy of the customization solution, customers are advised to provide the following core parameters:
Magnetic performance requirements: such as maximum magnetic energy product (BHmax), coercive force (Hcj), remanence (Br); working environment: temperature range (default -50℃~350℃), whether it is in contact with corrosive media; dimensions and tolerances: shape, dimension drawings or 3D models (support complex and special-shaped designs);
Magnetization direction: axial, radial or multi-pole magnetization requirements. Shanghai Young Magnet provides free magnetic circuit simulation services to assist in optimizing the design and avoiding performance redundancy or insufficiency.
Q2: Compared with NdFeB magnets, what are the irreplaceable advantages of SmCo magnets in customization?
A2: Smco magnets are particularly suitable for the following customized needs in harsh scenarios:
Extreme temperature: high temperature stability far exceeds that of NdFeB (Smco has a magnetic loss of <5% at 350°C, while NdFeB is usually limited to 180°C);
Corrosion resistance: no electroplating is required for long-term use in humid and salt spray environments, reducing coating costs;
Anti-demagnetization: insensitive to vibration and radiation, suitable for aerospace and military equipment;
Long life requirements: The life span can reach more than 20 years in high-temperature motors and sensors.
Q3: How long does it usually take to deliver customized Smco magnets? Are expedited orders supported?
A3: The standard customization cycle is 4-6 weeks (including material preparation, sintering, machining and magnetization), but Shanghai Young Magnet ensures efficient delivery through the following measures:
Pre-sintered blank reserves: shorten raw material processing time;
Flexible production line: supports small batches (starting from 100 pieces) to large-scale orders;
Expedited channel: for urgent needs, it can be compressed to 2-3 weeks (specific technical parameters must be provided to confirm feasibility).
