Product Details
Aluminum Heating Element for Cordless Soldering Iron
Aluminum Ceramic heating elements 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.
Process of Ceramic Element
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.
Material Properties of 95% Al2O3 Alumina ceramic
