Hi to all.
I know that type of wood effects on the stiffness of the future product.
There is next available wood in my country for ski or snowboard production: beech, ash, birch and aspen. (there are also other types but it seems to me that they are not suitable).
I have no experience in this area, but I wish and I am going to start soon. I just know that in the place of incerts must be harder wood.
May be someone can advice which combination of wood strips is possible to use from above mentioned list of wood. Also which wood is better to use in the place of inserts?
Thank you in advance!!

Apsen is pretty close to Poplar, which is a popular choice for ski/snowboard cores. If I were you, I'd start there. Ash makes a good stringer, and is also good under the inserts.
Here's some information that will be useful:

Ash is a great wood for skis. Try to break a piece, then you know why. Its not super-lightweight, but a good choice for normal skis. If you build some powderskis, it will be too heavy.

As I have read ash is good material for the middle part of the board because of the strength. But it is better to use another wood for the rest in order to make ski or snowboard lighter.

Yes.
Many also put a stronger but heavier wood just inside the sidewalls for solid edge grip. You can get as creative as you want when designing cores. It's something that you have to experiment with to achieve your desired results.
These pictures will give you an idea of how complex you can get.

That Burton core wow,
Best bet is to start simple and work your way up to the more complex stuff.

In this case, it is all about trial and error. But good advice is never superfluous.
Thank you all!!
