Large And Small Quantities Of Electric Resistance Wire.
Custom Electric maintains a large inventory of electric resistance materials, including conventional alloys, high temperature alloys, and specialty materials. In most instances, large and small orders for wire, ribbon, rod, and strip can be filled within 48 hours.
Changing Alloy Technology.
For years, 80% nickel, 20% chrome alloys were used to fabricate electric heating elements. This material provides excellent mechanical properties in the hot state, but is limited to temperatures of 2190º F (1200º C).
Today, iron/chrome/aluminum alloys are replacing nickel/chrome in many applications. The most significant benefit of the iron/chrome/aluminum alloy is higher operating temperatures, up to 2150° F (1150° C). This translates to higher surface loading and increased productivity.
Other benefits of iron/chrome/aluminum materials are from two to four times longer service life and no spalling oxides to contaminate furnace loads.
Radiant And Protective Tubes.
In addition to Kanthal APM and APMT extruded tubes, Custom Electric can provide cast tubes.
Note: New products always are being added to inventory. If you do not see what you need, contact Custom Electric.
KANTHAL and NIKROTHAL alloys are generally available in wire or strip form.
