It grows in Europe from Scandinavia and Northern areas of Russia farther South. It is common for British islands, also can be found in North America and East Asia.
Most important are Black (A. glutinosa)Specked alder (A. incana), which grows in European part of SIC and Northern Siberia. Alder has no core. It has high water resistance. It has light and soft wood. Can be cut well, not breaking during threading, not friable, not cracking during drying. Ductile and compliant for processing in all directions, it is applied in such important items as musical instruments: In certain accordions all wooden parts are from alder. Just-cut white alder quickly become yellow up to orange tones, but later on bright yellow color loses its luster, the wood becomes grey though butt remains yellow. Dry wood in over splitting and cross-section has also no bright yellow color but when covered by oil or drying oil again gains not such bright as in fresh cut but quite intense even color that distinct it from other kinds of wood. Typical weaknesses of alder is that it is drilled very bad (last place among known breeds of craft wood). Another weakness of this wood, smooth by texture and color in general, it has somewhere core iteration in a stile of longitudinal narrow brown dashes and sometimes as darker wide places.
On sunshine the alder wood loses his orange tone in two three months, its color becomes similar to the color of mature pine wood
The wood of white alder is slightly brighter and stronger then yellow-red wood of black alder.
