Top-Quality Fecral Heating Element Wire Direct From The Factory

Iron Chrome Aluminum (FeCrAl) alloys are high-resistance materials typically used in applications with maximum operating temperatures up to 1,400°C (2,550°F). It is widely used in industrial furnace, household appliances, industry furnace, metallurgy, machinery, aircraft, automotive, military and other industries producing heating elements and resistance elements. FeCrAl is usually used for high temperature furnaces in the heat treating, ceramics, glass, steel, and electronic industries. Other common applications include: heating elements (hair dryers, ovens, toasters, kilns), model and high power motor and recovery charge ignition, heat sealers, poly cutters, foam cutters, resistors, rheostats, current-temperature controls, lab inoculating loops, release mechanisms, ceramic support in kilns. FeCrAl 13/4 is an alloy with 13% chromium and 4% aluminum. It can be used at temperatures up to 950 ° FeCrAl 25/5 is an alloy with 25% chromium and 5% aluminum. It can be used at temperatures up to 1250 ° FeCrAl 21/6 is an alloy with 21% chromium and 6% aluminum. It can be used at temperatures up to 1250 ° FeCrAl 23/5 is an alloy with 23% chrome and 5% aluminum. It can be used at temperatures up to 1250 ° FeCrAl 21/4 is an alloy with 21% chromium and 4% aluminum. It can be used at temperatures up to 1100 ° FeCrAlNb 21/6 is an alloy with 21% of Chrome and 6% of Aluminum with the addition of Niobium (Columbio), – It can be used at temperatures up to 1350 ° FeCrAlMo2 27/7 is an alloy with 27% of Chrome and 7% of Aluminum with the addition of Molybdenum, – It can be used at temperatures up to 1400 °
