Several factors should be examined in choosing a heating element. They are temperature, atmosphere, life and power or heat load required. The temperature referred to is actual element operating temperature. It is based on the inter-relationship of furnace temperature, element watt loading, and the ability of the element to radiate the heat
Heating element material- a material for use as a heating element should have the following properties- i. High specific resistance, so that only a small quantity of wire is required to produce a given amount of heat ii. High melting point, so that high temperatures can be produced iii.
Tungsten is used as heating elements in electric furnaces which must withstand high temperatures. Because retains its strength at high temperatures and has a high melting point, elemental tungsten is used in many high-temperature applications. In addition, Tungsten is extremely corrosion resistant.

10.1.5.4 Hot wire welding. The resistance heating of a wire can be used to increase the weld metal deposition rate by feeding a separate (I 2 R heated) wire into the weld pool. The wire is heated using a low voltage of typically 8–15 V from a separate a.c. power source.
Electric Furnace: Update: So after a few months the element did finally break, although it was partly my fault. After reading some of the comments and doing more research, a simple controller to cycle the element on and off is recommended as the element is more lik

Examples of pricing for popular models is referenced in the "To Order" box.
Nichrome: Most resistance wire heating elements use nichrome 80/20 (80% nickel, 20% chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath this layer will not oxidize, preventing the wire
We supply heating elements for all types of high-temperature furnace in the form of ribbon, sheets, rods, twisted wire, wire bundles and wire mesh heaters. Our materials belong to the group of refractory metals. Molybdenum and tungsten are the two materials that are most commonly used in high-temperature thermal processes.
Resistance Heating Elements. Electric type resistance elements consist of a high temperature resistance alloy either nickel-chrome alloy or iron chrome aluminum alloy, usually formed in sinuous, loops or coils. The elements may be supported from the furnace sidewalls on refractory hooks or alloy hooks, suspended from the roof with alloy hanger
Its lack of reactivity with MgO refractories make it the most suitable alloy for enclosed heating elements, especially those operating in the higher temperature ranges. The oldest and most common electric heating alloy, N8 is long established as the world standard of quality among all metallic heating element materials.
Electric radiant heating uses heating elements that reach a high temperature. The element is usually packaged inside a glass envelope resembling a light bulb and with a reflector to direct the energy output away from the body of the heater.

Resistance heating alloys (PDF document, 1.7 MB)
The core of the resistive heater parts, through to the heating electricity to convert electrical energy into heat energy, the material has high temperature resistance, the oxidation resistance, the high temperature deformation, etc . Electric heating plate can be divided into stainless steel electric heating plate; ceramic electric heating
Since an electric heating element transfers heat by convection and radiation to the interior of the furnace and to the load, the element surface temperature is always higher than the furnace/process temperature during the heat-up and soaks portions of the firing curve.
