Magnesium

With 98%MgO,light sillicone treatment, wattage loading less than 10w/square meters .It can stand about 1050 Centigrade annealing

HTM is high temperature powder with light silicone treatment,mainly used in air heating elements with wattage loading less than 10W/cm2 . It can stand about 1050 centigradeannealing and requires immediate sealing. Mainly used in Coil Tubular Heater; Oven Tube and other high wattage loading heating elements.
