Providing exceptional abrasive wear resistance and relatively strong compressive strength compared to other iron-carbon alloys, white iron is a popular choice for applications in numerous industries. It can be found in machine components that have to withstand a lot of wear and abrasion, such as in grinders, mill liners and pump impellers that have to move abrasive materials.
White iron is formed when the metal cools so quickly during solidification that carbon combines with the iron to form iron carbide, also known as cementite. Because it also contains relatively little silicon, there is less free graphite present in white iron. This gives the alloy its distinctive white coloration on the surface as well as its high wear resistance. However, the highly crystalline structure of the metal also makes it much more brittle than other forms of iron. This means the use of white cast iron is more limited, although its high corrosion resistance combined with its ability to resist abrasion still makes it useful in certain applications.
