Professional Anodisers Give a Sneak Peek into the World of Anodising

If you aren’t really familiar with the ins and outs of the metal industry and metal’s diverse applications today, don’t worry, you’re not alone. A lot of people just see magnificent structures, gadgets and tools everywhere, but hardly pay much attention to the delicate and specialised processes that made them.

One of the most important methods involved in metal treatments and transformation is anodisation. This is a purely technical industrial term which refers to the process of increasing the thickness and toughness of certain metals like aluminium and titanium, as well as other alloys, in order to make them harder, more durable, and aesthetically pleasing.


Why Anodised Aluminium Makes Better Cookware Options in Your Kitchen

When it comes to selecting cookware and other kitchen utensils, many people think stainless steel is the way to go, but with the advent of high-quality ceramic and anodised aluminium products, your options have become diverse, and you get to choose from an array of more efficient, budget-friendly, and durable kitchenware.

Most people are yet to realise that stainless steel is in fact a combination of several metals like chromium, molybdenum, and nickel, all of which can sometimes contain particles that can mix with foods. These days, health-conscious folks consider anodised aluminium a safer alternative for cookware in the kitchen. This is because the anodising process effectively coats the bare metal surface, making it virtually nonporous, and preventing the aluminium from coming in contact with food.

Anodising Aluminium for High-Quality Products and Eco-Friendliness

As it is highly resistant to corrosion, aluminium is one of the most preferred metals for both industrial and aesthetic purposes. When anodised, an aluminium product may last longer, look better, and even becomes 100% recyclable for other applications. This saves a lot of energy and other resources needed to produce aluminium straight from raw materials.

How Anodising Helps Aluminium

Aluminium is already highly resistant to corrosion in itself because of its inherent protective oxide layer. The anodising process enhances this property, along with its other fine characteristics, to create a more durable and versatile product. A thin yet strong finish, called anodic coating, is added to the aluminium surface, resulting in the second hardest man-made substance next to diamond—anodised aluminium.

Anodising Automotive Hardware for Protection Against Corrosion, Wear

Aluminium is now the preferred material of major manufacturers in the automotive industry due to its overall cost-effectiveness, while at the same time being environment-friendly, as well. According to the Aluminium Association, various studies have shown that a fleet of aluminium cars would help reduce an equivalent of 44 million tons of carbon emissions.

These benefits are enhanced further through various metal polishing and finishing techniques that produce a stronger alloy surface for staying power. In 40 years of steady growth and popularity, the automotive use of aluminium is now only second to that of steel.

When Engineering and Polishing Made Aluminium a Worthy Rival for Steel

When Ford’s 2015 F-150 pickup rolled out, a lot of people probably didn’t expect it to harbour a secret. At first glance, it looked like the hulking pickup truck’s body was made in “standard” terms using steel, making it almost indestructible (given its off-roading nature). When Ford itself revealed, however, that the 2015 F-150’s body is made not of steel, but of aluminium, many people raised their eyebrows in disbelief. How would aluminium even be able to withstand the F-150’s intended off-road purpose? Its strength is quite reminiscent of foil wraps and soda cans, right?

Not if you consider brilliant engineering and science. Aluminium is, indeed, a “weakling” if you consider the heavy loads that steel can easily support, but it possesses qualities that steel doesn’t have. For one, it’s very malleable (able to be shaped to extreme limits without breaking) and very elastic.

Chemical Etching: A Popular Aluminium Anodising Pre-Treatment Process

Standard anodised aluminium, which is a main product of companies such as Badger Anodising, is a curious thing. For one, aluminium itself is already somewhat corrosion-resistant per se (thanks to the natural formation of aluminium oxide that essentially acts as a “shield”). However, the process of anodising itself makes the material so much more resistant to the elements, essentially making it nigh “invulnerable.” Furthermore, anodising is far from the only chemical processing aluminium may undergo.

Indeed, there are numerous other processes that aluminium can go through before being anodised. One such process is called etching. Derived from the German word which means “to eat,” etching (also known as metal etching, chemical milling, etc.) is the process of cutting into a metal surface using acid. Metal etching is a common industrial manufacturing technique, though it is also an artistic technique European masters such as Albrecht Dürer and Rembrandt, to name a few, have utilised.
