Any metal that is cast is inherently weaker than metal products that are drop forged.
It all has to do with the molecules in the iron. In a cast product, the molecules are random and haphazard. In a drop forged product, the molecules are 'forged' to conform to the shape of the object, thus making it stronger. The best and most expensive hand tools you can buy are drop forged.

What material is more brittle wood cast iron steel or glass?
Cast iron is very brittle in its basic form, with yield point very close to fracture point. However, glass is the most brittle, having no yield point - it is perfectly elastic before failure
What is the yield strength of cast iron?
For the usual run of cast iron, The yield stength almost coincides with its fracture strength - cast iron is very brittle and fractures at usually more than 20000 pounds per square inch. DUCTILE cast iron is one of the several irons that DO yield before cracking.
What is the classification of cast iron?
Grey cast ironWhite cast ironMalleable cast ironDuctile cast iron
Is malleable iron a cast iron or wrought iron?
Malleable means can be hammered. Cast iron will crack or break into pieces; it's not malleable. The word wrought means hammered. You could have used a dictionary for definitions; this isn't really an engineering question. The cast iron with carbon content of less than 0.2% is called wrought iron or pure iron. Wrought iron is very soft, plastic and easily deformed, but its strength and hardness are lower, so not widely used. Malleable cast iron is produced from white cast iron, which is made from hot liquid iron with certain chemical components. The white cast iron needs to be treated by malleablizing, such as graphitizing or oxidation and decarbonization, then its metallographic structures or chemical components will be changed, so can become into malleable cast iron. +++ So yes, Malleable Iron is a Cast Iron, but a much less brittle species enabling it to be used almost as a grade of steel. It is an important mechanical-engineering material. ' Wrought Iron was the ancestor of Mild Steel but became obsolete and no longer made, by the early 20C. It was very uneconomical, as well as very labour-intensive in very unpleasant conditions to make; and its internal structure and inconsistent quality rendered it totally unsuitable for the new engineering demands developing rapidly from the 1850s onwards.
Is cast iron different from iron?
cast iron consists of 2% - 4% of carbon in it. cast iron is pig iron remelted and thereby refined together with definite amount of limestone,steel scrap, and spoiled castings. it consists of small % of sulphur, silicon,phosphorus and manganese wrought iron is highly refined iron with a small amount of slag forged out into fibres. it consists of 99% iron. it is almost the purest form of iron. it is highly ductile,rusts extremely quickly, it cannot be heat treated
Hard brittle iron is iron is poured into a particular shape?
Cast iron
Where gun barrels made of cast iron?
No. Cast iron is brittle, and shatters like glass.
Can you name brittle materials?
glass and cast iron
The properties difference between mild-steel and cast-iron?
Cast iron is more brittle then mild steel
What are the example of brittle materials?
Glass, ceramic ,cast iron
Is brittle a physical property of metal?
some metals (cast iron for example) are brittle- it is a physical property
What material is more brittle wood cast iron steel or glass?
Cast iron is very brittle in its basic form, with yield point very close to fracture point. However, glass is the most brittle, having no yield point - it is perfectly elastic before failure
Who is the Non ductile metals?
Cast iron, is one example of a non-ductile metal. Unlike ductile metals, copper, steel, aluminium - cast iron is too brittle to be reworked.
Why brittle fracture occurs in grey cast iron?
Gray cast iron contain high amount of carbon in the form of flakes, the major strengthening element. These flakes cause the cast iorn to become strong yet brittle, in other words they become stress risers due to their brittleness, hence the part itself becomes brittle.
Are some materials brittle?
Some brittle materials are cast iron, concrete, high carbon steels, ceramics and glass. A brittle material is easily shattered and has little resistance against fracture.
Why is cast iron more brittle than mild iron?
Brittle because it contains impurities such as carbon and sulfur. The structure of the molecules in iron, particularly when cast, is such that it is almost crystalline in nature and breaks easily. The addition of carbon and other metals into the mix gives you more malleable compounds that are less brittle and can convert it to what we refer to as steel.
What is hard and brittle iron that is formed into a particular shape by pouring the liquid metal into a mold?
I think it would be cast
