Unfortunately, the answer to this question is quite complex and is dependent on a host of variables, not all of which may be obvious.

High-temperature furnaces must withstand high temperatures that melt materials, such as titanium, without damage.

High-temperature furnaces must withstand high temperatures that melt materials, such as titanium, without damage. Usually made of graphite, these furnaces frequently cause contamination with reactive carbon, which can cause damage to the manufactured products. Fully metallic furnaces and heating elements made of suitable materials, on the other hand, are a clean solution. 

Sweden’s Sandvik acquired privately owned Custom Electric Manufacturing Co. of Wixom, Mich. Custom Electric manufactures  original and replacement heating elements for electric and gas furnaces for the North American market. The business will be reported as part of the product area Kanthal within business area Sandvik Materials Technology. The deal will further strengthen Sandvik’s position in industrial heating systems. Custom Electric will continue to go to market under its own brand.

Since the development of commercial electric heating elements at the beginning of the 20th century, oxidation and corrosion resistance have been primary goals in the creation of new high-temperature resistance and construction alloys and ceramic materials.

Renowned for their high melting points, refractory metals are widely used in the construction and design of components for high-temperature furnaces.

The XSB ashing furnace provides ideal conditions for ashing petrochemicals, coal and other hydrocarbons.

Custom Electric Manufacturing Co. manufactures original equipment and replacement elements for heating industrial furnaces to temperatures as high as 2280°F (1250°C).

Sandvik’s Kanthal-branded materials and systems have long been the standard solution for electrical heating elements when it comes to FeCrAl (Kanthal®) and NiCrFe (Nikrothal®) metallic alloys as well as Super™ (MoSi₂) and Globar® (SiC) ceramic heating elements.
