Choosing aluminium profiles

[Voicecoil]

In the final analysis, rigidity is the most important thing, so check the figures for the moments of inertia (Ix, Iy) for the different profiles before making your choice. There are also other vendors/manufacturers such as Motedis, Item, Maunsystem, Misumi and KJN in the UK.

As well as Kanya.
Kanya is not the cheapest, but is the best in the marketplace, with a very wide range of extrusions and excessories.
Also there is extrusions that are heavy duty as well as the light so if you need more rigidity, use the heavy versions.
We sell Kanya by the way. ;0)

We also have some Isel extrusion thats on sale as well.

I had not heard about Kanya! What makes you say those are the best in the marketplace? Do you ship to Finland? Do you have similar fastener solution as the MiniTec Power-lock fastener available?

[Gary]

One of the first to bring to the market this type of products, swiss-made, and a very large range. yes there are a very large range of connectors, and you will see them in this link.

yes we ship worldwide, and the website should work out the shipping costs, but if not, just email me directly.

Thanks for you answer. I checked the moment of inertia and there is indeed a big difference between the 45 series and the 40 series profiles. The 45 series is way more rigid. Since the rigidity of the base is the most important thing, maybe it is a good decision to spend a bit more on the better profiles?

Absolutely. As aluminium isn't as stiff as steel you need to get clever and use extrusions that make the best use of the material to get a rigid frame.

Thanks for your help! I will go with the larger/stiffer aluminium extrusions.
