1. Insulation is used to prevent the Nichrome coil to contact the sheath. 2. The properties of nichrome vary depending on its alloy. 3. The material cost is approximately 1 % of nichrome . 4. The heating element is made of ~ 14meters of 2mm thick Nichrome wire. 5. Usually a thin nichrome wire is used. 6. :If you are aiming at a high operating temperature you need something like Nichrome . 7. Nichrome heating elements were controlled by pulse-width modulation ( PWM ) of transistors.8. The invention of nichrome alloy for resistance wires improved the cost and durability of heating elements. 9. The ?A001 was canceled at an early stage . the designers employed external nichrome thin film resistors. 10. Calrod heating elements have resistance wire ( nichrome ) insulated by ceramics from the outer metal shell.
