Interactive tool, magnet selection
Magnet grade finder
Type in the minimums, nominals and maximums off a drawing and every NdFeB grade and every Recoma, VACOMAX, XG and XGS samarium cobalt grade that can’t meet them grays out. What’s left is what you can buy, with the cheapest coercivity class named and the exact limit each gray grade misses.

Interactive tool, beta — sourcing and landed cost
Landed cost estimator
Describe a sintered NdFeB magnet and see what it lands at from five places at once, split into material, processing, tooling, logistics and duty — with Europe shown as both Estonia and Germany, since they share a duty lane and differ by a factor of two and a half on labor. The yield engine runs underneath it, so the block each part consumes is calculated rather than assumed. It is a beta: it compares regions, it does not price your supplier, and it does not calculate margin.

Interactive tool, magnet performance
Magnet field and temperature calculator
Give it a disc, ring or block in any of 135 grades — sintered neo, grain boundary diffused, SmCo and alnico, and it works out what a gaussmeter reads above it, where the shape puts the operating point, and how far the demagnetization curve has to move before the loss stops being reversible. Move the probe off the axis and a map of the field appears under it. Drag the temperature and watch the knee arrive.

Interactive tool, magnet machining
Magnet machining yield calculator
Describe the magnet, the block you can press, and what your machines can hold. The calculator works through every legal route from one to the other and ranks them by material yield, machine time and cost per good part. It plots the whole spread, so you can see whether the winner is genuinely better or just lucky, and quote from a percentile instead of the optimum. It runs in your browser and sends nothing back.
