Product Name : Fecral Alloy introduction:electric Iron Chrome Aluminum Alloy Material is a Ferrite Alloy, High Temperature in the Atmosphere, Especially 0cr27al7mo2 Alloy Material, Its Relatively Long Life. Since Fe-cr Alloy is a High Electric Resistance Alloys, the Resistance is High, in the Component Design Can Choose the Larger Size of the Alloy, to Extend the Service Life of Alloy, Iron Chromium Aluminum Alloy Electric More Excellent Antioxidant Resistance, Relatively Good Performance of Anti-carburizing, the Atmosphere and Surface of Sulfur Pollution By Sulfur Has a Good Atmosphere Corrosion Resistance. Widely Used in Industrial Furnace, Metallurgy, Machinery, Electrical Appliances, Aircraft, Automotive, Military and other Industries Producing Heating Elements and Resistance Elements. Defects in Iron-chromium Alloy Materials are Mainly Low-temperature Strength, as the Temperature Increases, the Plasticity Increases, the High Temperature Effect of the Weight of the Device Itself Will Slowly Stretch Deformation Caused By Component, the other a Long Time to Use with High-temperature Furnace Cooling , Alloy Grain Growth and Brittle and Can Not Cool to Be Bent. fe-cr Alloy Wire, Strip grade: 1cr13al4 1cr21al4 Ocr21al6 Ocr23al5 Ocr25al5 Ocr21al6nb Ocr27al7mo2 specifications: Wire: Φ0.05 --- Φ10 Mm strip: (0.05 - 0.1) × (5 - 250) Mm bar: Φ12 --- Φ30 Mm flat Yarn: 0.025 × (0.4 - 4) Mm fe-cr-al, Ni-cr, Ni-cr-fe Ribbon with Their Specification and Characterristics grades performance 1cr13al4 0cr23al5 0cr25al5 0cr21al6nb 0cr27al7mo2 the Main Chemical Composition. cr 12.0-15.0 20.5-23.5 23.0-26.0 21.0-23.0 26.5-27.8 al 4.0-6.0 4.2-5.3 4.5-6.5 5.0-7.0 6.0-7.0 fe margin margin margin margin margin re amount amount amount amount amount nb — — — dosage. 0.5 — mo — — — — dosage. 1.8-2.2 max.continuous service Temp.of element (°c) 950 1250 1250 1350 1400 melting Point (approx.) °c 1450 1500 1500 1510 1520 density g/cm3 7.4 7.25 7.1 7.1 7.1 resistivity μω.m, 20°c 1.25±0.08 1.35±0.06 1.42±0.07 1.45±0.07 1.53±0.07 heat. 20°c J/g.°c 0.490 0.460 0.494 0.494 0.494 fast Life Value.h/°c temperature.°c 900 1250 1250 1350 1400 hours.h ≥80 ≥80 ≥80 ≥80 ≥80 thermal Conductivity.kj/m•h•°c 52.0 60.2 46.1 46.1 45.2 expansion Coefficient A×10-6/°c 15.4 15.0 16.0 16.0 16.0 tensile Strengthmpa 588-735 637-784 637-784 637-784 637-784 the Number of Repeated Bendingf/r ≥5 ≥5 ≥5 ≥5 ≥5 hardness(h•b) 200-260 200-260 200-260 200-260 200-260 microstructure ferrite ferrite ferrite ferrite ferrite magnetic magnetic magnetic magnetic magnetic magnetic
