Product Description

Brief Introduction

1.4725, known under the designation CrAl4, is a ferritic iron-chromium-aluminum (FeCrAl) alloy. Its primary purpose is to serve as a heating conductor alloy, and it is classified as a special alloy steel with magnetic properties.The defining feature of this alloy is its combination of a high electrical resistivity and a low temperature coefficient of resistance, which makes it an excellent and stable material for electrical heating applications. This allows it to operate at high temperatures; its maximum service temperature in air is 1000°C, where it maintains good oxidation resistance.
In terms of physical characteristics, it has a density of 7.3 g/cm³ and a relatively low thermal conductivity. Mechanically, it offers high strength, with a typical tensile strength around 850 MPa.A critical operational characteristic is its susceptibility to cold brittleness. This embrittlement can occur in two scenarios: if the material is used above 1000°C and then cooled, or if it is operated within the temperature range of 400–550°C. Designs must avoid these conditions to ensure component longevity and safety.
