Engineering tools for
induction heating
Frequency selection, power sizing, skin depth, Curie temperature, and material conductivity — calculated from physics, not guesswork.

Process Parameter Reference
Frequency ranges, power densities, target temperatures and process notes for every major induction heating application — hardening, joining, forming, melting and more.
Select material
Choose from 10 categories and 40+ specific alloys. Resistivity, permeability, Cp, density, and Curie temperature auto-populate.
Set objective
Surface hardening, brazing, annealing, melting, wire annealing — target temperature auto-fills from material + process.
Enter geometry
Shaft, tube, plate, gear, billet, wire. Enter the key dimension — wall thickness, coil length, line speed for wire mode.
Get results
Frequency range, skin depth, power per part, recommended supply kW — with Curie and safety alerts.
Skin Depth & Frequency
Why δ = √(ρ/πfμ₀μᵣ) is the central equation in induction heating — and how material properties and geometry both drive your frequency choice.
Curie Temperature
How ferromagnetic materials lose permeability at the Curie point — and what the "Curie knee" means for your power supply and heating curve.
Supply Sizing
P = m·Cp·ΔT / (t·η) — how mass, heat time, coil efficiency and radiation losses combine to determine the kW rating you need.
Coil Geometry
Solenoid, pancake, hairpin, split-return — how coil type and coupling gap affect efficiency, temperature uniformity and power factor.
Non-Magnetic Materials
Why aluminum, copper and titanium require higher frequency and more power — and how to compensate with coil geometry and coupling distance.
Continuous Wire
Dwell time, mass per metre, throughput — how line speed, coil length and wire diameter interact in continuous induction annealing.
Tube & Pipe Heating
Wall thickness — not OD — drives frequency selection. How to avoid opposite-wall heating in thin-walled tubes.
Susceptor Heating
Why powder, scraps and ceramics can't be directly induction heated — and how a conductive graphite or metal susceptor solves it.
Surface vs Through Hardening
How case depth, frequency and dwell time interact — and why surface hardening needs frequency an order of magnitude higher than through hardening.
