SmCo Disc & Block Magnets

Custom SmCo disc and block magnets for compact high-temperature assemblies with strict dimensional and magnetic consistency needs.

Target Buyer:Best for projects requiring custom geometry plus reliable field behavior at elevated temperature.

SmCo disc and block magnets for harsh industrial environments

Capability Highlights

Disc and block geometries optimized for compact assemblies.
Temperature-resistant magnetic performance for harsh duty cycles.
Supports custom tolerance, chamfer, and edge-protection requirements.

Typical Applications

High-temperature position and speed sensor modules
Actuator and latch assemblies in aerospace and defense hardware
Magnetic holding and coupling structures in industrial equipment

Engineering Focus

Define tolerance-critical dimensions tied to magnetic circuit behavior.
Align shape, coating policy, and assembly method to field conditions.
Ensure machining plan accounts for brittleness and yield risk.

Decision Boundary

Disc and block programs are most reliable when dimensional CTQ and magnetic-force targets are paired with a manufacturable machining route from day one.

Go Signals

Critical dimensions and tolerance bands are tied to function, not copied from legacy prints.
Magnetic target and measurement condition are both stated in the RFQ.
Prototype quantity and scale-up path are defined together.

Hold Signals

Tolerance requests are tighter than function requires with no trade-off discussion.
Drawing revision is unstable during quote stage.
Acceptance criteria for edge quality and chipping are missing.

Buyer Deliverables for First Review

2D/3D drawings with CTQ markings and revision baseline.
Magnetic requirement window with test fixture assumptions.
Prototype acceptance checklist covering geometry, field, and appearance.

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Dimensional tolerance readiness	Reviewed per geometry and process route	Determines assembly fit and downstream scrap risk during pilot builds.
Thermal reliability margin	Application-defined against grade capability	Improves stability of magnetic force across operating cycles.

RFQ Checklist

Provide 2D/3D drawings with critical dimensions and tolerances.
Specify operating temperature, media exposure, and required lifetime.
State magnetic performance target and test acceptance criteria.
Include sample quantity and release timing for qualification.

Risk Controls

Geometry-to-process mismatch: Run DFM review before quote lock and agree a manufacturable tolerance plan.
Sample rework due to unclear acceptance criteria: Document test conditions and pass/fail values in RFQ stage.

Buyer FAQ

Do you support custom dimensions and tolerances?

Yes. We support custom disc and block geometry programs with engineering review before sample release.

Can we start from prototype quantities?

Yes. Prototype and pilot quantities are supported with a scale-up path to repeat production.
