How to specify a magnet
The better the specification, the faster and more accurate the benchmark. Here is what each field means and why it matters.
Drawing or specification — dimensions, magnetisation direction, coating, tolerances. A drawing beats a description.
Grade or magnetic properties — either the grade (e.g. N42SH) or the required Br and HcJ at operating temperature. If you know the operating point, say so.
Dimensions and tolerances — mark which dimensions are functional.
Coating — and the adhesive or assembly process it must work with.
Magnetisation — direction, and whether delivered magnetised.
Maximum operating temperature — including short peaks.
Prototype quantity — how many samples you need to test.
Annual volume — expected, even if approximate. It determines which production routes are relevant.
Delivery country — for customs, incoterms and lead time.
Target price and current landed-price range — optional, but it lets us tell you immediately whether an alternative route is worth pursuing. We do not need to know your current supplier.
