Sm2Co17 Magnets (2:17)

Sm2Co17 magnets for high-temperature and high-field-retention programs up to 350°C with strict reliability requirements.

Target Buyer:Best for teams prioritizing thermal headroom, magnetic retention, and long-lifecycle reliability.

Sm2Co17 samarium cobalt magnets up to 350C operating applications

Capability Highlights

Higher temperature capability for severe thermal environments.
Strong long-term magnetic stability in aerospace and defense duty cycles.
Supports precision-machined geometries for complex assemblies.

Typical Applications

Aerospace propulsion-adjacent sensors and control modules
Military and defense systems with sustained high-temperature duty
Downhole and energy tooling with elevated thermal exposure

Engineering Focus

Validate irreversible loss margin at maximum operating temperature.
Control tolerance and surface integrity for thin-wall or complex shapes.
Align material route with qualification test profile and lifecycle target.

Decision Boundary

Select Sm2Co17 when irreversible-loss risk must stay controlled under sustained high-temperature duty or harsh lifecycle exposure above typical SmCo5 conditions.

Go Signals

Operating envelope and thermal peaks are measured, not estimated.
Program explicitly requires high retention at elevated temperature over lifecycle.
Qualification scope includes thermal cycling and degradation checkpoints.

Hold Signals

No verified thermal map exists for worst-case conditions.
Acceptance criteria are limited to one-time initial measurement.
Documentation ownership for qualification evidence is unclear.

Buyer Deliverables for First Review

Thermal mission profile and maximum allowed magnetic drift.
Qualification matrix with pass/fail limits and sample counts.
Revision-controlled specification package for geometry and field target.

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Recommended operating range	-55°C to +350°C	Protects critical assemblies from magnetic degradation under high heat.
Thermal stability retention	High retention under qualified duty profile	Improves reliability for long-cycle aerospace and defense programs.

RFQ Checklist

Define max continuous and short-term peak operating temperature.
Provide target magnetic property window and demagnetization constraints.
Specify geometry, tolerance, and magnetization direction for each part.
Include verification plan (thermal cycle, vibration, salt fog if required).

Risk Controls

Underestimated thermal peak exposure: Run application-level thermal mapping and include margin in grade selection.
Qualification delay from incomplete test definition: Freeze acceptance criteria and test method in RFQ stage.

Buyer FAQ

Do Sm2Co17 magnets require protective coatings?

Many applications run uncoated due to intrinsic corrosion resistance, but final surface treatment depends on assembly, media exposure, and handling requirements.

Can you support aerospace documentation workflows?

Yes. We can align material and process documentation scope with your program requirement before sample release.
