Engineering reference tools
Five interactive reference tools for industrial induction heating — heat colour chart, process parameters, heating method comparison, d/δ efficiency chart, and resistivity vs temperature curves.
Reference Tools
Heat Colour Temperature Chart
Interactive black body radiation chart from 20°C to 1500°C. Drag the bar or click colour bands to identify temperature from colour — with process notes, steel phase data, and aluminium/titanium status.
Process Parameter Cheat Sheet
Typical frequency, power density, temperature ranges and heat times for 25+ induction heating applications — hardening, brazing, forging, melting and more. Filter by category.
Induction vs Other Heating Methods
Side-by-side comparison of induction, gas/flame, electric furnace, resistance and laser heating across 12 criteria — speed, precision, efficiency, safety and more.
Efficiency & Power Factor Chart
How electrical efficiency and power factor vary with the d/δ ratio — the workpiece dimension relative to skin depth. Interactive chart for solid cylinder, tube, and flat slab geometries.
Resistivity vs Temperature
Interactive chart showing how electrical resistivity changes with temperature for common metals. Features the dramatic Curie knee in ferromagnetic steel and nickel.
