What are the uses of high alloy cast iron?

Answer 1

White Cast Iron is silvery-white in color. It is hard and does not melt easily. It is not easily worked on a machine. Thus it cannot be used for delicate castings. It is mainly used for ornamental purposes.

Answer 2

It is used in making automobile,railway sleepers, gutter pipes, agricultural and machine parts, pipes, hollowware, stoves, and furnaces.

It is also used for making wrought iron and steel.

No longer for wrought iron. It was, but that material became obsolescent over a century ago, as it became uneconomical to make, its manufacture was very hard and unpleasant for the iron-workers, and it became mechanically unsuitable for all the new engineering demands developing in the late 19C. It was usefully a bit more corrosion-resistant than mild-steel, and I believe some was still being made and used in the mid-20C, but it was on its way out. The modern material for ornamental so- called "wrought iron" nowadays is Hot-rolled, or Black, Mild-Steel.

Cast-iron is not used for railway sleepers, though some sleepers are pressed or rolled steel plate. It may well be used for other track parts such as the rail chairs and some components of turn-outs (points), though. It is a very important material for precision-engineering components such as machine-tool bodies and engine-blocks. Very few if any building gutters and drain-pipes are made now from cast-iron, except perhaps for sensitive restoration work on 'Grade-1 Listed' ancient buildings - almost all such fittings are now plastic.

Answer 3

malleable iron is used for many types of threaded pipe fittings used for gas and Plumbing service

Black heart malleable cast iron is mainly used to produce the iron casting parts with impact, shake or torsion functions. Normally used to produce rear axle housing castings, spring bracket, low pressure valve body, pipe fittings, tools and wrenches. Black heart malleable cast iron is also called as ferritic malleable cast iron.

Answer 4

White iron is too brittle for use in many structural components, but with good hardness and abrasion resistance and relatively low cost, it finds use in such applications as the wear surfaces (impeller and volute) of slurry pumps, shell liners and lifter bars inball mills and autogenous grinding mills, balls and rings in coal pulverisers, and the teeth of a backhoe's digging bucket (although cast medium-carbon martensitic steel is more common for this application).

Answer 5

It is used for heavy crushing material, car brake discs and vice or machine parts. AQA DT pg 18
