Nickel Chrome Manual Polished High Density Cartridge Heaters, For Industrial Use, Dimensions (mm) : 6.5 Mm

standard sheath material is 321 stainless steel which provides good thermal conductivity, and resistance to corrosion and scaling. welded end disc made from the same material as the sheath provides a positive seal against moisture and other contaminants. grade “a” nickel-chrome resistance wire precisely wound on a high purity magnesium oxide core places the resistance wire as close to the inside of the sheath as possible. a high purity magnesium oxide (mgo) powder is used to fill all remaining space inside the sheath. heater is then swaged, which compacts the magnesium oxide grains into a solid mass. the standard termination for is type n, 10" (254 mm) long nickel conductor lead wires externally connected to solid conductor terminal pins.
