GRWAY® Ceramic Heating Element For Hakko Soldering Station were developed based on ceramic lamination technologies, which are mainly used for automotive and various industrial applications such as soldering iron, kerosene & gas equipment, pellet burner and water heating.
First, painting the high melting point metal (tungsten or molybdenum manganese) paste on to the Al2O3 casting briquette in coordinate to the circuit design, then another layer of sintering additives. After that, repeating the process to build multiple layers. Then, they are sintered together under 1600 °C hydrogen gas environment. Finally, nickel leads are brazed at 800 °C onto the metal end and put on with Teflon sleeve, which make it a MCH heating element.
Internal Heating elements are protected from oxidation due to sintering into one-piece ceramic body structure.

It is a new type of high efficient heater, which can save more than 20%-30% power effect compare to PTC ceramic heaters. Our alumina ceramic heaters have many excellent features:
Excellent insulation (the leakage current is < 0.5 mA under voltage 4500V/1S testing with no breakdown)
High reliability, stable resistance, no electric noise
Good chemical resistance
full compliance with EU RoHS (no lead, cadmium, mercury, hexavalent chromium, PCBS, and other harmful substances)
