What is the best malleable metal?
March 6, 2023 (Last update: November 10, 2026)

Malleable steel is a type of metal made from iron, carbon and other alloying elements. It differs from other types of steel through its high ductility and toughness, which means it can be deformed easily without breaking and is resistant to cracking and fracture.
Kneedbaar staal was developed as an alternative to cast iron and has similar properties, but is less brittle and therefore more resistant to breakage. It’s often used in applications where high strength and toughness are required, such as in the automotive industry, construction and mechanical engineering.
Malleable steel can be processed and formed into different shapes and sizes, such as plates, bars, tubes and cast parts. It can also be welded and soldered, making it a versatile material for many different applications.

If you’re looking for malleable steel, your best option is a specialised metal supplier or steel dealer. They can advise you on the different types of malleable steel available and which one is best suited to your application.

When do you use malleable steel?

Malleable steel is used in applications where high strength, toughness and formability are required. Some common applications of malleable steel are:

Automotive industry: Malleable steel is used in the production of car parts such as axles, springs, hubs and steering components. The high load-bearing capacity and toughness of malleable steel make it suitable for these applications.

Construction: Malleable steel is used in the construction of bridges, tunnels, structures, roof frameworks and more. Its high strength and toughness make it ideal for these uses.

Mechanical engineering: Malleable steel is used to produce machine parts such as shafts, gears, bearings and couplings. The high strength, toughness and formability of malleable steel make it suitable for these applications.

Industrial applications: Malleable steel is used in various industrial applications, such as the production of pipes, pumps, valves and fittings. Its high strength and toughness make it suitable here as well.

In general, malleable steel is used in applications where high strength and toughness are required, while a certain degree of deformability and machinability is also needed.

Which type of malleable steel is best?

The best malleable steel for your specific application depends on several factors, such as the load, environmental conditions and the desired properties of the material. Here are some of the most common types of malleable steel and their characteristics:

Ferritic malleable steel

This type of malleable steel has high strength and toughness, making it suitable for applications with high loads and shocks. It also has excellent corrosion resistance and can be used in high-temperature environments.

Pearlitic malleable steel

This type of malleable steel has higher strength than ferritic malleable steel, but slightly less toughness. It’s often used in applications where high strength and stiffness are required, such as in mechanical engineering and structural work.

Martensitic malleable steel

This type of malleable steel has the highest strength of all malleable steels, but is less tough than the other types. It’s used in applications where high strength and hardness are required, such as tools and dies.

Austenitic malleable steel

This type of malleable steel has high toughness and corrosion resistance, but lower strength than the other types. It’s used in applications where high toughness and corrosion resistance are important, such as in the food and pharmaceutical industries.

What is the most commonly used and favourite malleable steel metal?

There are different kinds of malleable steel available, and which one sells the most depends on the specific application and the customer’s preference.

Our favourite is Lepstick metal from OriginalFix. You can use Lepstick steel metal for all kinds of jobs, such as holes in an engine block, pipe repair, bonding metals and hard plastics, boat repairs and much more. An important advantage of this product is that it can be used on damp surfaces.
