what is cast iron?

Answer 1

Cast irons have a bigger sweet spot but you lose a little feel
they are a very hard metal

Answer 2

Iron made in a mold. A durable metal with an exceptional capability to hold and transfer heat. It has a higher carbon content (2.0% - 4.5%) and is less malleable (more brittle). It is shaped by pouring it in a fluid, molten state into molds. Steel alloys are next in decreasing order of carbon content (approx. 0.2% - 2.0%), followed by wrought iron, which has less carbon content (approx. 0.2%). This makes wrought iron tough, but more malleable. It is more easily shaped by heating and hammering (forging).

A brittle alloy with high carbon content: high compressive strength, low tensile strength. Iron that is remelted in a cupola or furnace and cast into specially shaped moulds; cast iron is softer than steel Cire perdue (Lost wax) technique of casting.

Cast iron usually refers to grey cast iron, but can mean any of a group of iron-based alloys containing more than 2% carbon (alloys with less carbon are carbon steel by definition). It is made by remelting pig iron, often along with substantial quantities of scrap iron and scrap steel, and taking various steps to remove undesirable contaminants such as phosphorus and sulfur, which weaken the material.

Answer 3

Iron that is heated until it is liquid, then poured or 'cast' into a mold.
Iron can also be heated then hammered and bent into shape, called wrought iron.

Answer 4

You have asked this question in 'Golf Section'. There is no cast iron, in Golf. But, a type of Golf for short putting is called 'Irons'.
