The same selection logic we apply when reviewing your drawings — written down so you can use it before you ever talk to us.
Material families, NdFeB grades, coatings, tolerances and an RFQ checklist on one printable sheet. Pin it next to your CAD station.
What the grade number actually measures, what the letter suffix tells you about temperature limits, and the grade-selection mistakes that cause demagnetization in the field.
