Focus on Alinco
Alinco has been the key reference in the field of sheet metal work for many years now. Thanks to our comprehensive range of machines, we are able to handle practically all types of machining operations. To deliver fair and high-quality customized products is our goal, and in aiming at precisely that, we highly value the principles of correct processing of stainless steels primarily. Stainless steel is cut on copper bearers. Our enthusiastic team of 50 experienced and highly qualified professionals is ready and willing to realize your projects. We distinguish ourselves from our competitors in that we can perform the more difficult work and deliver fine finish, but of course we can also handle the simple and/or industrial work. Alinco concentrates on sectors such as pharmaceuticals, food, industry, machine construction… We can either provide you with designs or work on the basis of your own plans. You can contact us for piecework, for small and medium-sized series but also for large projects.

Customers often ask us for the ‘passivation’ or ‘chemical passivation’ of their products, while they actually mean pickling.
Passivation without pickling is not helpful. Passivation is in fact the process of forming the self-repairing layer of active stainless steel that comes in contact with the air. Suppose you cut through a 5 mm sheet. After being cut, the sheet’s 5 mm cross-section becomes ‘free’ for the first time, as the self-repairing corrosion-resistant layer of the stainless steel has not yet formed. It takes a few hours and this is a process that only starts when the bare material is exposed to the air. The process is called passivation, and can be accelerated with the help of a passivation product, but this will only speed up the process.

Plasma keyhole welding installation
Our sister company Deprest recently added a plasma keyhole welding installation to its equipment.
In plasma keyhole welding, instead of being bevelled, the plates are tightly clamped together. Quite simply put, the material is fused together, as it were, at a very high temperature. The process is suitable for welding together plates or tubes up to 8 mm.

Corrosion and surface treatment of welded joints
In the early 1990’s, the NIL (Dutch Welding Institute) conducted extensive research (Source: NIL) on the effects of various standard treatments on the corrosion resistance of welds; you will find an interesting article in attachment.
Welding produces a brown, rust-like discoloration. In order to get rid of this discoloration, pickling, glass blasting, or any type of brushing or sanding treatment is applied, sometimes hot.

Focus on safety mirrors
A stainless steel safety mirror is a perfect alternative to a glass mirror. Mirror quality, with a slightly different look, but perfect as a mirror.
Since the mirror is not made of glass, but from a solid stainless steel plate, there is no risk of shards.

Galvanic corrosion forms when 2 different metallic materials are combined within the same component. This can lead to an anode/cathode reaction, and accelerated corrosion of the less noble material. The latter may then suffer a corrosion rate far higher than that to be expected without any contact with the nobler partner material.

Plate rolling or press brake?
Alinco has a whole range of plate rolling machines that give us the technical ability to roll sheet, cones and other reducers. You can find an overview of our plate rolling machines here. Our sister company, Deprest, also has a number of plate rolling machines which are more suitable for thicker work (they roll plate to a thickness of 40 mm). However, plate rolling has its limitations. For thicker plate, for example, for 8 mm and up, you won’t find any plate rolling machines that can centre these plates at smaller diameters. In the case of 8 mm, you need a lot of force and you can’t do that with 50 mm rollers. Even a fairly long roller bench won’t have small rollers.
A classic example here are cones. These sometimes tend to go down to small diameters. Take a cone that goes from 500 mm to 100 mm with a length of 1000 mm and a wall thickness of 6 mm. There’s no other choice than to make the cone in 2 parts and fold these instead of rolling them, and these are manufactured using segment folds. There are many folds close to each other so you get a more or less round shape. If you do this using the right folding tool, it goes fairly well.

Stainless Steel Super Mirror 8
Alinco regularly works with mirror stainless steel of the highest quality: super mirror 8. This is top grade mirror stainless steel that really reflects and shows absolutely no distortion. This is not to be confused with BA (Bright Annealed) grade which is also sold on the market as mirror stainless steel but is actually much less reflective and does have dull spots and the like.
Top-quality super mirror 8 is not cheap, admittedly, but is really a very attractive plate. We always stick to the same high quality from the same manufacturer. I was surprised recently to learn that some dealers also offer super mirror 8 at prices that seem very interesting.

What causes current increase of stainless steel prices?
In previous newsletters, we have regularly drawn attention to how the price of stainless steel is rising these days. The price rises have been with us for several weeks already and there are expectations that they will continue to increase over coming weeks and months. It is difficult for the moment to predict where the price of stainless steel will peak but there is no doubt it will rise considerably.
But aside from knowing that they will rise, it it sometimes interesting to reflect on the reasons for these prise rises for stainless steel.

Datasheet: stainless steel super mirror 8
Enclosed you find the data sheet of the super mirror = mirror 8 finish that Alinco uses and keeps on stock in stainless steel 304 and 316.
In case the esthetical aspect is important, finishes like BA (bright annealed) are not sufficient, while the quality of mirror 8 is always excellent. Mirror 8 is more expensive (about double the price of BA quality, that is often also called 'mirror'), but it's worth paying more.

Alinco 35 years
Happy birthday, Alinco!
These days, Alinco becomes 35 years old. Alinco - an abbreviation for Aluminium - Inox (= stainless steel) - Construction, was founded in 1978 by about 15 people after the company they worked for, Soetens -De Belie went bankrupt. They were merely people who worked there as well as some related families and investors.

New: Plasma cutting
New: from now on, Alinco offers you the service of plasma cutting with a very high quality, comparable to lasercutting or watercutting.
It is not Alinco itself that bought the machine, but it's sister company Deprest, who is specialised in the production of pressure vessels and all sorts of tanks. The pieces are cut there, but Alinco wants to offer their clients the same service. This is possible because of frequent transports between the 2 companies; the client will get the same prices from both companies.
Photo enclosed shows pieces in metal with a thickness of 15 and 40 mm, and comes directly from the machine. As you can see, the pieces don't need any extra machining for normal use.

Our website will be modified during the next few weeks, maybe months. At this moment, a lot of the information on the site is scattered, that's why we want to put some things together and specify or clarify other things. Moreover, we have the ambition to give a lot more technical information about stainless steel and steel in general, so that it can be used by ourselves and by others for looking up information.
Especially the English and French pages might temporarily be incorrect, because we will first make a structure and write pages in Dutch before translating them in English or French.
