DESCRIPTION
FeCrAl 135 is a ferritic iron-chromium-aluminium alloy (Cr content is around 22%) suitable for temperature applications up to 1250°C.
This alloy has an excellent life time in sulfur environments and particularly when atmosphere is also oxidizing.
FeCrAl 135 is used in domestic appliances, toasters, fan heaters, laboratory furnaces, etc. Due to its resistance to carbonaceous atmospheres this alloy is widely used in production of fuel burners and cigarette lighters.
