YUECI KEJI · Rare-earth permanent magnets
Precision magnet supply, engineered from your drawing.
Custom-first sourcing of sintered NdFeB, SmCo, Alnico, ferrite and finished magnetic assemblies — with documented quality and environmental management systems behind every grade.
Full customisation (OEM & ODM) is our default mode; standard grades are available where they fit.

Material science, measured
Every grade is quoted on measurable quantities
We specify permanent magnets the way an engineer reads a datasheet: by remanence, coercivity, energy product and the temperature the assembly will actually see. Values are confirmed per grade and geometry against your drawing — we do not publish unverified figures.
Open the NdFeB range- Br
- Remanence — per grade
- Hcj
- Intrinsic coercivity — per grade
- (BH)max
- Maximum energy product — per grade
- Tmax
- Maximum working temperature — per grade
- Tolerance
- Per drawing, confirmed before tooling
- Coating
- Specified with your environment
Qualification wall
Systems and designations on record
These are management-system certificates and enterprise designations registered to YUECI KEJI — not product approvals. Scanned copies of the four certificates and of the national designation plaque are published on the certifications page with their numbers and validity periods exactly as printed, including periods that have already closed. Product-level conformity is confirmed per order and market requirement.

How a custom order runs
From drawing to series supply
- Step 1
Send your drawing
Geometry, operating temperature, environment and target performance — or the assembly the magnet has to serve.
- Step 2
DFM and grade review
Our engineers confirm the achievable specification and flag anything that would move cost or risk consistency.
- Step 3
Sample approval
Small samples are supplied with freight covered by the buyer, then measured against the agreed specification.
- Step 4
Series supply
Production lead time runs 7–20 calendar days, with sea or air freight arranged to your delivery terms.
Consistency
Magnetic measuring tools are part of our own catalogue
The instruments used to check remanence, pull force and grade consistency are the same family of products we supply. Order terms include a pre-shipment report confirmation step before the balance is settled, so what was agreed is what is verified.

About YUECI KEJI
Who we are, in one screen
YUECI KEJI is a rare-earth permanent magnet supplier working from Jiangxi, China, with sintered NdFeB as the core of the range and SmCo, Alnico, ferrite and finished assemblies around it. We are organised around custom work: most orders start from a drawing rather than a catalogue line.
Our buyers are concentrated in Europe, Southeast Asia and India, with smaller volumes to the Americas and domestic projects. That mix shapes how we document a product: system-level quality records first, then per-order confirmation of anything a market or application requires.

- Magnet assemblies supplied ready to fit
- Test instruments for incoming inspection
- Quality and environmental system documentation
