Large Stocks Thermal Spray Tafa 24ca Wire (0Cr25Al5)
(Common Name:0Cr25Al5,Aluchrom-O)
0Cr25Al5 is a iron-chromium-aluminium alloy (FeCrAl alloy) characterized
by high resistance, low coefficient of electric resistance, high
operating temperature, good corrosion resistance under high
temperature.It is suitable for use at temperatures up to 1250°C.
Typical applications for 0Cr25Al5 are used in electric ceramic cooktop,industrial furnace,heaters.Normal composition%| C | P | S | Mn | Si | Cr | Ni | Al | Fe | Other | | Max | | 0.06 | 0.025 | 0.025 | 0.70 | Max 0.60 | 23.0~26.0 | Max 0.60 | 4.5~6.5 | Bal. | - |
