Made-to-order: selected aluminum colors

Discover the selected aluminum colors

 

Hello everyone,

To follow up with the made-to-order option to choose the VK-X leather colors, I am presenting today the aluminum colors that will also be available for this service!

We selected 6 different anodizing colors according to the leather colors that were chosen.

 

1) The 6 available aluminum colors

 

Our signature Classic Gray aluminum (used for the VK-1, VK-2 and the ODS-1) will be available with 2 variations on neutral tones: Dark Gray and BlackThose colors will go well with the available leather color options.

We have also chosen to present 3 new original colors with the VK-X. A clear Champagne, a discrete Rose Gold and at last a Dark Bronze, our coup de Coeur.

 

 

2) How to choose your VK-X made-to-order colors

 

Choose the colors and materials of your VK-X could not be done online without seeing them for real. Indeed, the made-to-order headphones won’t be pictured in advance unlike the VK-X series editions since it would require crafting 36 different headphones. For this reason, we decided to send a swatch book that will enable to discover the leathers, the aluminum and their colors for real, in order to make your choice informed and easier!

3) Learn more about the aluminum

 

I also published an article that describes how we make and color our aluminum cups. Aluminum is a light gray malleable metal that requires an operation called anodizing in order to be used for our headphones. It is a bit technical, but do not hesitate to have a look; I will be happy to answer if you have any question: http://journal.aedle.net/2018/05/23/vk-x-aluminum/

Aluminum and anodizing

 

Hello everyone,

 

1) Made-to-order option 2 selected: the aluminum colors

 

This is Paul. As promised, I am coming back today to present the second article in a series dedicated to our made-to-order headphones. We first introduced our leather, how it’s made, and where it comes from. Today, we are going to talk about the aluminum and, more specifically, about its anodizing

I will take a moment to remind you of the most recent poll of our options for personalization:

2) The Anodization of Aluminum and its alloys

 

The second critical piece of our headphones, the aluminum cup, is a result of a process that is known as anodization or anodic oxidation. Aluminum is a lightweight metal, highly malleable, and resistant to corrosion. However, in its raw state, it is soft and has impurities. Anodizing gives the part concerned protection against wear and corrosion due to oxidation by carrying out the latter in a controlled environment (aluminum oxidizes spontaneously upon contact with air). The oxide layer that covers aluminum is called alumina; it is a very hard, uniform, transparent and insulating body.

To anodize aluminum, one proceeds in the same way as for the electrolysis of water (a phenomenon caused by the passage of an electric current in the water, cf diagram below). There are, however, some differences: the workpiece is the anode (negative potential in yellow below) and an ionic solution (sulfuric acid most of the time) is used, pure water being non-conductive. Due to the electric current, the water molecules are decomposed into hydrogen and oxygen; the surface of the workpiece is therefore directly exposed to the oxygen formed by the decomposition of the water, resulting in the formation of alumina.

 

 

The electrolytic treatment produces a much thicker layer of alumina than during the natural oxidation process (1). The structure of the aluminum is porous and allows the electrolyte to conduct the current to the metal. Once the anodizing is carried out, we go to the staining step (2) and finally to the sealing of the pores present in the alumina in order to reinforce its resistance (3). This last step is done in boiling water or steam in general, but can also be done cold.

 

 

3) aëdle aluminum

 

To obtain a perfect rendering, we chose the T-6063 aluminum, low alloyed with magnesium and silica, frequently used in aviation and architecture. It is ideal for machining complex shapes and its clean, smooth surface is particularly suitable for anodizing. In order to achieve the desired result with regard to our “cups”, it is necessary for us to perform aluminum machining in the mass, piece by piece.

 


 

 

4) Choice of available aluminum colors for the VK-X

 

I invite you to read this other article dedicated to the choices we made in terms of aluminum colors for the VK-X:

All this was a bit technical so please do not hesitate to ask questions and we will be happy to answer!
