0Cr23Al5 Low Resistance Wire FeCrAl Alloy High Heat Wire Forging , Rolling , Annealing
0Cr23Al5
0Cr23Al5 is one kind of normal material of Fe-Cr-Al alloy.
FeCrAl alloy has the characteristic of high resistivity,low temperature resistance coefficient,high operating temperature,good anti-oxidation and anti-corrosion under high temperature.
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 alloys are characterized by excellent oxidation resistance and very good form stability resulting in long element life.
They are typically used in electrical heating elements in industrial furnaces and home appliances.
Fe-Cr-Al alloy with high resistivity and serviceability temperature than that for NiCr alloy and also has lower price.
Forms:wire, bar, strip,sheet/plate,forging,tube/pipe,etc.
Manufacture Processs The manufacture started with producing ingot by advanced vacuum melting process. The wire production includes forging, rolling, annealing and drawing. From the ingot to the final thin wire, manufacture process is operated with high standard quality control system. There will be quality test for each batch of product, such as test to diameter tolerance, content, hardness, etc.
