What is a metal tubing?

Metal tubing is made from different metals, or metal alloys, in different shapes, sizes, wall thicknesses, diameters, etc. according to the applications and requirements of each industry and specialist project. 

The major groups are classified according to their metallurgical structures, shapes, sizes, finishes, features, or performance specifications.

What are the different types of metal tubes? 

Selecting the correct metal for the specific purpose is one of the most important factors in ensuring relevance and correct application.

Some metals offer exceptional strength-to-weight ratios, while others will excel at chemical and corrosion resistance, thermal stability, or rigidity.

Aluminium tubing

It is exceptionally light, yet strong and highly resistant to corrosion and absorbs heat well. To enhance specific qualities, it can be alloyed with zinc, copper, silicon, manganese, or other metals.

It is perfect for temperature control applications like solar power, refrigerators, and air conditioning systems. hydraulic systems, braces, fuel lines, and frames.

Copper tubing 

Copper tubing is made from a pure, non-ferrous metal that naturally occurs in the earth’s crust. It is highly corrosion-resistant with excellent thermal and electrical conductivity. 

It is highly suitable for plumbing, heating, refrigeration, HVAC systems, and transporting hot and cold liquids.

Brass tubing 

Brass tubing is made from an alloy of copper and zinc to attain greater strength, corrosion resistance, aesthetics, and electrical conductivity.

It is often used in hardware, plumbing, radiator, gas, air, and hobby applications.

Bronze tubing 

Bronze tubing is created by alloying copper and tin for good toughness, tensile strength, corrosion resistance, and electrical and thermal conductivity. To enhance the desired qualities, it can be further alloyed with phosphorus, manganese, aluminium, or silicon.

The different bronze alloys are mostly used in the boat industry, as component parts, heat distribution systems, or as an alternative for copper pipes.

Stainless steel tubing 

It is made from steel alloyed with chromium, silicon, nickel, carbon, nitrogen, and manganese.

It has remarkable corrosion resistance, chemicals and other aggressive fluids, tensile and pressure strength, sanitary and aesthetically appealing.

Some specialist stainless steel tubing is known as duplex, lean duplex, or nickel alloys.

It is one of the most commonly used metal alloys, suitable for chemical and high-temperature applications, medical purposes, the pharmaceutical industry, the food and beverage industry, and decorative and design purposes.

Steel tubing 

Steel tubing is usually made from an alloy of iron and carbon. It is highly durable and strong with a high resistance to heat, abrasion, and knocks. It can also be alloyed with other metals to improve specific qualities or it can be coated with zinc, creating galvanised steel tubing with greater corrosion resistance.

Steel tubing is commonly found in structural applications, transport of fluids, gasses, and liquid waste, as components of industrial machines, hydraulic lifts, and mills.

Titanium tubing 

It can either be provided as extremely expensive commercially pure lightweight titanium with exceptional strength and corrosion resistance, or alloyed with other metals such as aluminium, and vanadium.

Titanium’s low density means it weighs less than half what steel tubing weighs, but with its strength multiplied, making it the metal tubing of choice in a diverse range of applications, including in aircraft, shipping, hydraulics, marine, nuclear plants, and the medical, chemical and petrochemical industries.


Arguably the next most important consideration when selecting the appropriate metal tubing is the dimensions required for the particular project. 

The various applications require different inside and outside diameters, wall thickness, lengths, and fitting into inaccessible or limited spaces. 

For example, transporting bulk liquids will require mega tubes, while for medical purposes they can be almost microscopically small, each presenting its own challenges because some metals can be formed in smaller dimensions but not large proportions, for instance.


The shape in which metal tubing is manufactured may be important for various reasons, like rigidity, free flow of liquid or air, etc. Metal tubes are therefore manufactured in a variety of shapes, including round, square, rectangular, oval, hexagonal, or customised shapes. 

For some applications, metal tubes need to be coiled, spiralled, finned, or fluted, while other applications require straight lengths from a few metres to ultra lengths. 

  • Round tubing is widely used in structural and industrial environments, such as columns, scaffolding, and automotive frames, to transport liquids and gasses, in heating or cooling apparatus and appliances, or in plumbing.
  • Rectangular tubing is found in several environments, including construction, industrial applications, engineering and more. 
  • Square tubing is commonly used in the manufacturing and construction industries, as steel fencing, rails, security gates and doors; and many others.
  • Oval tubing is often used in tight spaces and is popular for its aerodynamic and decorative qualities.


Some metal tubes may need to be processed to a bright finish, while others need to be galvanised, painted or plated. As an example, certain applications will require a perfectly smooth inner or outer surface to minimise friction, abrasion, and resistance, or it may need to be non-reflective, decorative, etc.

Not all metals can be finished in the same manner and when this is an important factor, it may be necessary for the inner or outer surfaces of the tube to be finished by polishing, anodising, galvanised, powder coated, painted, or plated in a certain way. 

Important features of metal tubing


For some applications, the tubing has to be flexible enough to coil in long continuous runs in either a wrapped reel or spring format.

Heat dissipation 

Especially in applications like heat exchangers, refrigeration, and air conditioning, cooling, metal tubes with characteristics like malleability, conductivity, heat retention, heat dispersion, weldability, etc., is required. Some types of tubing have fins or flutes formed or attached to the exterior surface to increase the surface area for quicker dispersion of temperature.

Tubing has fins or flutes formed on the exterior surface which greatly increase the surface area for heat dissipation. This is particularly important for tubing used in heat exchangers, refrigeration, and air conditioning applications.

Multi-layered metal tubing 

Used in particular for transporting or heating fluids, it is constructed of multiple concentric or matrix layers of the same or different materials, including other metals, and thermoplastics, for sealing and insulating the metal tube. 


Metal tubing used in the medical, chemical and pharmaceutical industries in particular, need to be sterilized by autoclaving, dry heat, gamma irradiation, and chemical disinfectants. Some metals will react adversely to these conditions.

Seamless or Welded tubing

  • Seamless metal tubes can withstand much higher internal pressure, making them imminently suitable for use in industries like aerospace, chemical processing, instrumentation, medical, shipbuilding, and oil and gas conveyance.
  • Welded Steel Tube is a more affordable option and is mostly used in industries such as construction, food and beverage, automotive, and civil engineering.

Re-Drawn & Precision Nickel and Stainless Steel Tubes

When non-standard sizes,  thin-walled, or a tightly toleranced welded or seamless stainless steel or nickel tube is required, it can be manufactured by Special Metal Alloy’s specialist mill partners on short lead times.

Performance Specifications

Metal tubes can also be selected according to the performance specifications required for the project or application.

  • Pressure rating for the maximum inner pressure the tube can withstand carrying fluids. 
  • Maximum vacuum pressure that can be created in the tube for use in vacuum systems and electronics.
  • Minimum bend radius rating is particularly important in the construction industry and determines the acceptable amount of deformation the tubing cross-section can tolerate.
  • Temperature range rating is particularly important when conveying fluids or gas in the tubes, including both the temperature of the fluids and ambient temperatures within which the tubes are used.
