Excuse me, is anticorrosive wood divided into two kinds of wood: Pinus sylvestris var. mongolica. Mongolian wood and Finnish wood? thank you

Russian camphor and Finnish pine, even if you don't understand, can still be distinguished from the surface. First, you can look at their wood grain. The grain of Pinus sylvestris var. mongolica is thin and small, while the grain of Finnish wood is thick and big, which is what we often call mountain grain. One more thing, we can look at their density because of the material of Pinus sylvestris var. mongolica. Mongolian wood is softer, while Finnish wood is more realistic, which can be judged by its weight. The above two points can be distinguished even by people who don't understand anticorrosive wood. You can try.
