Alderwood types and DIN names

Similar to the lime tree, there are also several European species in the alder tree and a species occurring exclusively in the USA and Canada - that is the American red alder, also known as Oregon alder. In our case, the following species are common:

  • Schwarzerle
  • Gray alder (or Weißerle)
  • Italian alder (especially in Calabria and Corsica)

With regard to the wood, the individual species differ only insignificantly.

Appearance

The alder is a sapwood tree, which means there is no difference in color between sapwood and heartwood. The gray alder is always slightly lighter and finer than the black alder, this applies to both the color and the grain.

Grain

Alder wood has a very fine drawing, with widely dispersed, but very fine pores. Annual rings are only weakly recognizable, the wood rays are very fine and are particularly dense.

colour

Common shades are reddish yellow to pale yellow, with fresh wood, the color can also turn into orange. However, this hue darkens to a brown color during drying. The surface shines matt with alder wood.

properties

Alderwood is rather light and rather soft compared to other native hardwood species. The Weißerle (gray alder) has slightly less strength than the black alder and is considered qualitatively inferior. Accordingly, the black alder is more valued and valued higher and preferably used.

Shrinkage and drying

With alder wood one finds only a rather moderate shrinking behavior. Like linden, alders are also very likely to upset. Proper storage during drying is therefore very important. Alder wood should be protected from direct sunlight during drying.

Deteriorated wood can be recognized by the following signs:

  • Formation of dark and blackish marbling
  • Crumbling of the wood
  • Swelling of the wood fibers

Deteriorated wood can no longer be used and no longer be burned. The wood structure is completely destroyed.

resistance

Alder wood can not withstand the weather when used outdoors. Completely under water, however, it is very durable. It is not resistant to fungal and insect infestation, but on the contrary extremely susceptible to it.

use

Especially in furniture making, and also in chairs, alder wood is often used as a substitute for expensive precious woods (especially walnut). That is also connected with its particularly favorable price. Alderwood is still widely used in musical instrument making today. American alder is increasingly used as a substitute for the also very expensive cherry wood.

Traditional use

Traditionally, alder wood has been used mainly for the tables of sewing machines. Smoke chips were usually made from alder.

Prices)

As sawn timber, alder wood costs around 500 - 700 EUR per m³, and steamed wood costs between 600 and 750 EUR per m³. American alder is usually offered in wood trade only in very small quantities and therefore at much higher prices.
