Materials

Coating Selection Guide

Compare corrosion resistance, conductivity, and suitable environments of nickel, zinc, epoxy, gold, and other coatings.

Principles

Magnetic Field & Surface Force

Gauss-to-Tesla conversion, Br remanence, and the factors that affect surface magnetic field.

Specifications

Magnetization Direction

Differences between axial, diametric, and multi-pole magnetization, suitable shapes, and how to specify when ordering.

Compliance

Compliance Certification

RoHS, REACh, conflict-free minerals (RMI), and heavy-rare-earth-free compliant export.

Compliance

Heavy-Rare-Earth-Free Compliant Export

NdFeB at 48SH and below, free of Dy/Tb, with the actual China compliant-export procedure to Taiwan already completed.

Safety

Safety Precautions

Handling, medical, children, and shipping (IATA) safety guidelines for powerful magnets.

Tools

Operating Temperature Calculator

Estimate surface field (Gauss), pull force, and the true safe maximum temperature by grade, shape (block / disc / ring), dimensions, and operating temperature. On desktop, compare two specifications side by side.

Tools
