Can you support OEM customization?

Yes. We support custom dimensions, magnetization direction, tolerance planning, and project-specific quality requirements.

What information should I send for an RFQ?

Please include target grade, geometry drawing, operating temperature, required quantity, and delivery destination.

Do you provide prototype and validation support?

Yes. We can support sample builds and help define acceptance criteria before mass-production release.

Can you handle global shipment requirements?

Yes. We support export-focused packaging and delivery coordination for international programs.

Buyer Toolkit

RFQ Data Pack That Cuts Back-and-Forth

Most sourcing delays happen before technical scope is frozen. This pack helps engineering and procurement teams send decision-ready inputs in the first inquiry.

Data Item	Typical Owner	Decision Impact
Thermal Profile & Duty Cycle	System engineering	Defines grade path and irreversible-loss margin before quote lock.
Geometry + Tolerance + Magnetization Direction	Mechanical design	Prevents sampling loops caused by fit or field-direction mismatch.
Validation Gates (Pass/Fail)	Quality + reliability	Aligns sample approval criteria so procurement can move to PO with confidence.
Forecast + Destination + Timing	Procurement + logistics	Improves lead-time and packaging assumptions for global delivery planning.

Program Flow Snapshot

A simple handoff sequence your team can reuse from first inquiry to production release.

Scope freeze (Day 0-2): Requirement baseline and open-issue list ownership.
Technical screening (Day 2-5): Grade path direction, key risk notes, and RFQ clarification set.
Sample planning (Day 5-10): Validation matrix and acceptance evidence definition.
Commercial alignment (After validation lock): Lead-time model, delivery milestones, and release conditions.

Execution Path

How Buyers Move from Selection to Launch

This is the recommended page sequence for cross-functional teams: product fit first, application risk second, execution model third.

Step 1

Select Product Family

Start from grade and geometry fit: SmCo5 vs Sm2Co17, operating temperature, and magnetization direction assumptions.

Step 2

Validate by Application

Confirm architecture against temperature envelope, lifecycle duty, and integration constraints before sample planning.

Step 3

Qualify OEM Execution

Review revision control, sample evidence, traceability, and global delivery governance before commercial lock.

SmCo Selection Snapshot for Engineering Buyers

This matrix helps cross-functional teams compare grade paths before launching a detailed RFQ thread.

Family	Best Fit	Key Metric	Why It Matters
SmCo5 Magnets (1:5)	Best for engineering teams that need compact high-reliability magnets with predictable thermal behavior.	Recommended operating range: -55°C to +250°C	Prevents under-specification when the magnet works near thermal limits.
Sm2Co17 Magnets (2:17)	Best for teams prioritizing thermal headroom, magnetic retention, and long-lifecycle reliability.	Recommended operating range: -55°C to +350°C	Protects critical assemblies from magnetic degradation under high heat.
SmCo Ring Magnets	Best for teams that need strict geometric consistency with defined magnetic orientation in ring form factors.	Concentricity capability: Defined per geometry and tolerance stack	Directly impacts field symmetry and system-level repeatability.
SmCo Disc & Block Magnets	Best for projects requiring custom geometry plus reliable field behavior at elevated temperature.	Dimensional tolerance readiness: Reviewed per geometry and process route	Determines assembly fit and downstream scrap risk during pilot builds.
