Cast iron is brittle and hard and resistant to wear. During the manufacturing process, some slag is added which gives wrought iron excellent resistance to corrosion and oxidation, however, it is low in hardness and fatigue strength. Wrought iron is used for fencing and railings, agricultural implements, nails, barbed wire, chains, and various ornaments. Non-ferrous metals include aluminum , copper, lead, zinc and tin, as well as precious metals like gold and silver.
Their main advantage over ferrous materials is their malleability. They also have no iron content, giving them a higher resistance to rust and corrosion, and making them ideal for gutters, liquid pipes, roofing and outdoor signs. Lastly they are non-magnetic, which is important for many electronic and wiring applications.
Aluminum is lightweight, soft and low strength. Aluminum is easily cast, forged, machined and welded. Because aluminum is lightweight, it is a good choice for the manufacturing of aircraft and food cans.
Aluminum is also used in castings, pistons, railways, cars, and kitchen utensils. Copper is red in color, highly ductile, malleable and has high conductivity for electricity and heat. Copper is principally used in the electrical industry in the form of wire and other conductors.
Copper is also used to make brass , an alloy of copper and zinc. Lead is a soft, heavy, malleable metal with a low melting point and low tensile strength.
It can withstand corrosion from moisture and many acids. Lead is widely used in electrical power cables, batteries, building construction and soldering. Zinc is a medium to low strength metal with a very low melting point. Ferrous metals such as cast and wrought iron or carbon steel are known for their tensile strength and durability. As a result, materials such as carbon steel are widely used in the construction industry to build the structures of bridges and skyscrapers.
Ferrous metals are also found in shipping containers, pipework, automobiles, railways and a range of both commercial and domestic tools. The high carbon content of ferrous metals means that they are vulnerable to rust when exposed to moisture, and therefore generally unsuitable for applications such as water pipes. Wrought iron is an exception to this as its purity means it resists rust, while alloying elements can also be used, such as chromium in stainless steel, to prevent rusting.
Since most ferrous metals are magnetic, they are often used in electrical and motor applications, as well as in other less obvious places, such as in your refrigerator door, so you can use a magnet to attach your shopping list to it! Ferrous metals have been in use for thousands of years and have a huge range of different applications, from the largest structures to the smallest nuts and bolts.
Non-ferrous metals are alloys or metals that do not contain any appreciable amounts of iron. All common titanium alloys can be fusion welded, or joined using solid state processes.

TWI TWI has a wealth of experience in areas related to the use of ferrous metals, including materials evaluation and corrosion management and welding metallurgy and weldability. You can find out more by contacting us, below: contactus twi.
Properties Ferrous metals share some basic properties, including being prone to rust and being magnetic. The list of common ferrous metal properties include: Durable Good tensile strength Good electrical conductivity Low corrosion resistance Silver in colour Recyclable Usually magnetic Ferrous metals can include a wide range of different alloying elements, including chromium, nickel, manganese, molybdenum, and vanadium, manganese.
This makes them ideal for use in aircraft and other applications. Ask the experts at All Metals Fabrication which metal is right for your next industrial or architectural metal fabrication project.

Alloys are mixtures of metal with an element to improve its properties or aesthetic.
For example brass is a mixture of copper and zinc. Alloys can also be classified as ferrous or non-ferrous. Non-ferrous metal may require a protective finish.
This finish is sometimes used to improve the aesthetics of the product it is used for. Ferrous and non-ferrous metals. Shelving made from metal angles. Orange, flaking rust on an old steel pier. Copper oxidised to a green colour.
