Malleable fitting are the fitting has the property of malleability.
This is a physical property of metals and metalloids, or any kind of matter. We call a metal malleable when it can easily be deformed, especially by hammering or rolling, without cracking the metal.
We are manufacturer of Malleable Iron Pipe Fittings and supply high quality Malleable Iron Pipe Fittings in both large and small quantities worldwide and offer you the best prices in the market.

Differences Between Malleable Iron & Cast Iron
Although they both contain iron, there is a major difference between malleable iron and cast iron. The main difference being that malleable iron is, well, malleable and cast iron is not. But there are other differences as well. We’ll need to talk about what exactly these metals are and how they are made.iron door pull handles
What is Cast Iron?
Cast iron is the result of smelting ore in a furnace, creating pig iron which has a high carbon content. Alloys are then added to the iron which is poured into molds and allowed to cool.
What is Malleable Iron?
Malleable iron starts out as cast iron, but an annealing heat treatment is applied to the cast iron to make it more workable and increase ductility. Consequently, malleable iron has much lower carbon content than cast iron. There are three different types of malleable iron:
- Blackheart
- Whiteheart
- Pearlitic
- Production
To make malleable iron, foundry workers add hematite ore during the annealing process. Depending on the need for ductility, they may also add sodium, cerium, or magnesium.
Cast iron is typically smelted in a bloomery. Usually, the furnace becomes too hot for other types of iron making and this is when the iron absorbs the most carbon. It is then poured into molds for cooling.
Properties
Malleable iron is easier to work with to make more intricate designs, such as luxury iron doors. On the other hand, cast iron is better known for its castability, meaning it is easily poured into molds without premature cooling because of its low melting point.
Composition
The annealing process of malleable iron causes it to form small particles of carbon that are shaped irregularly. This gives the iron more strength while allowing it to keep ductility. Malleable iron is relatively easy to machine, and it is shock resistant.
Cast iron contains about two percent carbon, which makes it stronger and more resistant to rusting. But this also makes it more difficult to machine because it is difficult to get a smooth surface with the material. This can also make cast iron more costly to work with as it reduces tool life.
Cost
Both cast iron and malleable iron are similarly priced. However, cast iron tends to be cheaper because it has a low melting point requiring less energy to heat it.
Function
Cast iron is used to make castings such as barbell weights in a gym or engine blocks. Malleable iron is better suited for decorative elements like iron doors.
