The 0Cr15Al5 alloy is an iron-chromium-aluminum (FeCrAl) based material known for its superior oxidation resistance, excellent electrical resistivity, and stable performance at elevated temperatures. With a typical composition of 15% chromium and 5% aluminum, it forms a dense oxide layer on its surface when heated, which protects the alloy from further oxidation and corrosion.
DLX Alloy’s 0Cr15Al5 bars are produced using advanced vacuum melting and precision rolling techniques, ensuring uniform composition and excellent mechanical strength. They are suitable for continuous operation in temperatures up to 1100°C, maintaining structural integrity and efficient conductivity.
