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 better for vibration cast iron or mild steel?
Typically mild steel can withstand vibration better because it has a higher density than the more brittle cast iron but cast iron may be better at absorbing vibrations than mild steel, due to its lower density.
Alloys are commonly used in manufacturing. Which of the following is not a reason to use an alloy instead a pure metal?
Cast iron is more brittle than pure iron.
Is cast iron expensive?
Ductile is a form of CI and it is much more costly then regular cast iron pipe
Is cast iron better than steel for a wood stove?
It depends on what it's being used for. Cast iron is great for engine blocks and anything that will be cast into irregular shapes, but cast iron tends to be brittle and can crack or break. Steel alloy tends to be tougher and holds up to abuse a little better. Also, cast iron is more difficult to weld. Your question doesn't specify what the cast iron is being used for so I can't be more specific.
What is platinum in its pure form?
It is a whitish, highly-malleable metal but with hardness equal to iron and highly resistant to corrosion. When impure, as with osmium or rhodium, it is more brittle.
The properties difference between mild-steel and cast-iron?
Cast iron is more brittle then mild steel

Difference between cast iron and mild steel?
The main difference between cast iron and mild steel is the carbon content. Mild steel has a lower carbon content than cast iron. This makes cast iron brittle, while mild steel is much harder.
Which has more atomic mass cast iron or mild steel?
mild steel
Is mild steel is more corrosive than cast iron?
yes
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
Alloys are commonly used in manufacturing. Which of the following is not a reason to use an alloy instead a pure metal?
Cast iron is more brittle than pure iron.
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.
Is cast aluminum furniture as strong as wrought iron?
In theory yes, both will serve you for many years. The lower priced in both wrought iron and cast aluminum tend to have more impurities in the raw material and thus can be more brittle. Cast Aluminum is more readily available and generally offers more selection.

Why cast iron would not be a suitable material to make car springs?
Although Cast Iron is very useful and is quite tough this also makes it a more brittle form of Iron. As well as having a fairly low Modulus of elasticity (or Young's Modulus), and therefore it does not have the required capabilities that would make it suitable for a car spring
