Despite being a very lightweight metal, even when alloyed, aluminium still accounts for 80% of the weight of an average modern aircraft.

Why are aluminium alloys so popular in aerospace engineering? Their strength-to-weight-to-cost ratio is unbeatable and the inherent corrosion resistance of aluminium extends the lifespan of the aircraft and reduces maintenance costs.

Different alloys are useful for different applications; 4342 for example is ideal for structural elements in the fuselage due to its strength, toughness, and its ability to withstand stress. Whereas in the wings, ribs and tension members are often made from 7075, due to its higher tensile strength and lower weight.

Today marks 70 years since the Routemaster bus was introduced to the world at Earl's Court Commercial Motor Show, before being quickly rolled out onto London's streets. Seating more people and yet lighter than the buses it was replacing, the Routemaster was easier to build, more fuel efficient, and much easier to operate.

The key to this was the extensive use of aluminium, especially in the bodywork of the bus, utilising engineering techniques pioneered in aircraft production during the previous ten years. The lower cost of procuring and working with aluminium made the production of the Routemaster much more attractive than many alternatives, while the lighter weight reduced fuel consumption and made it far more nimble amidst the capital's traffic.

Coupling this lighter structure with the first use on a bus of power steering, power-hydraulic braking, and an automatic gearbox made the Routemaster a welcome change to its cumbersome predecessors for both drivers and passengers. In fact, the Routemaster stayed in regular use on London's bus routes for fifty years and was so popular that it was voted one of the country's top 10 design icons shortly after it was finally withdrawn from service.

Stainless steel is one of the most sustainable construction materials on the planet. As well as the long service life of stainless steel components, even those exposed to the elements (which is sort of the point of stainless steel in the first place), stainless steel is 100% recyclable. Since it was first mass produced in the early 20th century, between 40% and 60% of all stainless steel produced has been recycled.

Our range of stainless steel products includes long products, flat products, marine and aerospace materials, tubular products and handrailing. Materials are sources from approved and highly reputable mills and our customers can have confidence that all materials supplied originate from trusted and proven manufacturers.

Aluminium bronzes have been in production since the 1850s, and since then there's been a consistent level of development in improving the performance of these alloys.

What has consistently remained in the performance of aluminium bronzes is the nature of aluminium. The strong affinity to form oxides means that any alloy of aluminium remains incredibly resistant to corrosion. The oxide layer on the surface of the metal protects it against everything from atmospheric moisture to barnacles.

What do the Boeing 787, the iPhone 15 Pro, and your gran have in common?

Well, not necessarily your gran. BS TA11, or Ti-6AL-4V, a titanium alloy with 6% aluminium and 4% vanadium, is the material of choice for medical implants such as artificial hips. The physical properties of titanium coupled with the fact that it doesn't react badly to being inside the human body and is far more resistant to corrosion than alternatives make it the ideal choice.

What are those physical properties? Well, it was developed for military applications and offers an incredible strength-to-weight ratio, as well as excellent impact toughness. These traits are why it is extensively used in both the latest iPhone and the Dreamliner.

In the iPhone, it offers improved protection over the aluminium used in the enclosures of earlier models. In the 787 this alloy's use reduces the weight of the aircraft considerably, and contributes towards its status as the most fuel-efficient plane Boeing have ever made.

It's been 20 years since the retirement of an aviation legend. British Airways' Concordes were all officially retired on 24th October 2003 (around four months after Air France had done the same).

One thing that most people probably don't know about Concorde is that its white paint job had a vital engineering function. The skin of the aircraft was, as is the case with most aeroplanes, an aluminium alloy. This was chosen for the usual reasons that it was lightweight, easy to work with, and relatively cheap. However, the skin of the plane would get very hot as Concorde shot through the air at twice the speed of sound.

One way to prevent the plane's skin heating so much it failed was highly reflective white paint, which actually reduced the temperature of the aircraft's skin by as much as 11°C.

The need to control the temperature of the outer surfaces of Concorde is one of the primary factors dictating its maximum speed of Mach 2.02.

Typically, when discussing the weight of materials, it's desirable to have less weight for a given level of performance. However, in architecture, there are times when it's the opposite. Like this, the Tuned Mass Damper in Taipei 101.

20 years ago today, Taipei 101 became (although still under construction) the tallest skyscraper in the world, a title it held for over five years. This huge ball is a vital part of what keeps this tall building standing, which is impressive when you consider that it was built within 200m of a major fault line in an area where typhoon-strength winds are common. Taipei 101 has been subjected to two serious earthquakes since its construction and came through entirely unscathed.

The Tuned Mass Damper is a large pendulum, weighing in at 660 tonnes, and measuring over five metres across. This huge ball of steel counters the vibrations that hit the building during high winds or earthquakes, allowing Taipei 101 to flex but not break.

One of the more remarkable metals we stock is AMS 5666, also commonly referred to as Alloy 625. A nickel-chromium alloy with the addition of molybdenum and niobium, it is very hard and doesn't require additional treatment.

Its strength and resistance to heat and all sorts of corrosive atmospheres make it an ideal material for critical elements within jet engines, where high-performance materials that simply won't fail are needed.

Today, 6th October marks the 194th anniversary of the start of the Rainhill trials, where Stephenson's Rocket won the competition to supply locomotives to the nearly completed Liverpool & Manchester Railway. This success, along with Locomotion No. 1 for the Stockton & Darlington Railway four years earlier made George and Robert Stephenson the pre-eminent builders of locomotives for much of the world.

Only 25 years from Richard Trevithick's first successful steam locomotive, Rocket was a showcase of everything the Stephensons had learned. One of the key secrets of Rocket's success was the use of multiple fire-tubes through the boiler. Most other locomotives used a single large flue, but Stephenson used 25 separate copper tubes to increase the surface area and more efficiently transfer the heat energy from the firebox to the boiler.

Copper was the ideal material, being easy to work with and resistant to the corrosion from the flue gases and the boiling water it would be subjected to. It was also lightweight, and much of the firebox was also constructed of copper to meet the trial's requirement of a weight limit, although this was replaced with more durable wrought iron for the locomotive's actual time serving the L&MR.

Copper is still used today for similar purposes, its corrosion resistance and thermal properties find it use in industrial radiators.

Aluminium might be considered a "modern" metal, especially when it comes to aerospace applications, but its use actually dates back to the dawn of powered flight. The Wright Flyer, the world's first working aeroplane, had a custom-made aluminium engine block.

A similar engine was in the Wright Flyer III, which on 5th October 1905 proved to be the first practical aeroplane, flying for over 24 miles at an average speed of just under 40 miles per hour.

The reason Wilbur and Orville used aluminium for their engine is the same reason it's still used today; it's much lighter than steel and much cheaper than titanium, and alloys of aluminium are strong enough to form vital structural components of aircraft.

Stainless steel is one of the most sustainable construction materials on the planet. As well as the long service life of stainless steel components, even those exposed to the elements, stainless steel is 100% recyclable. Between 40% and 60% of stainless steel is recycled.

Domestic use of stainless steel (including appliances and electronics) accounts for around 35% of the market, and unfortunately, it's here that we see almost a third ending up in landfill. In the automotive and construction industries, the vast majority of stainless steel is recycled after its long life cycle. All told recycled stainless steel uses 65% less energy to produce than new.

Righton Blackburns have been supplying the industry with stainless steel for over 100 years, building a reputation for quality and service with many customers in diverse market sectors.

198 years ago, on the 27th of September 1825, the world's first passenger rail service pulled by a steam locomotive began, at the Stockton & Darlington Railway. The first journey consisted of 31 wagons of coal and passengers, and one passenger carriage named Experiment.

George Stephenson's Locomotion No. 1 which was used in that first journey kept running for the S&DR for twenty-five years, despite the fact the time was famed for rapid developments in steam engine development. George's son Robert Stephenson won the Rainhill Trials for the Liverpool and Manchester Railway with his innovative Rocket just four years later, which was more reliable and twice as fast.

Like all of the early steam engines, Locomotion No. 1 was primarily constructed of cast iron and wood. After almost two centuries of improvements the materials used are stronger, lighter, and thanks to our commitment to quality, those provided to the rail industry by Righton Blackburns are more reliable.
