Ash types and DIN names

The ash also forms many different species. However, only a few species are really interesting for timber production. These are the common ash, which is native to our latitudes, and is the most important timber tree for the production of ash wood. In addition, the valuable Oregon ash plays an important role.

Other less significant species are:

  • the hanging ash
  • the Arizona ash
  • the American ash
  • the olive tree

In Asia, some ash species are native, such as the Japanese ash.

Appearance

Grain

Ash wood is a clearly recognizable coarse-pored wood with strongly pronounced annual rings. Also marbled and cloudy drawings are quite typical for ash wood.

colour

The sapwood and heartwood differ significantly in their color as soon as the heartwood has darkened. Typical color for all European and Asian species is a yellowish-white to yellowish-gray shade of heartwood. Especially the olive ash darkens against brownish to olive after. American ash species are generally lighter colored than the European ones.

properties

Depending on the place of origin, the properties of the ash are sometimes very different, and the wood weight can vary considerably. Basically, ash wood is very tough and hard and difficult to split. Above all, it has excellent elasticity properties and a high elastic strength, which is almost as good as with hickory wood.

Shrinkage and drying

Ash wood only moderately fades, outdoor drying is recommended, as washing out the tannic acid from the rain improves the quality of the wood and makes it easier to work. The rest of the drying (after about 12 months) should be carried out under a roof to avoid so-called Lohflecken by stagnant water.

resistance

Ash wood is only weather-resistant to a limited extent, and also not resistant to fungal and insect infestation. For a planned outdoor use, therefore, comprehensive protection must be provided.

use

Ash wood is mainly used today, where a high elastic strength is required - this is the case for example with tool handles, but also with sports equipment. Beautiful pieces are also processed to high quality veneer. White ash is often used as a veneer for particularly high-quality bedroom furniture.

Ash wood as firewood

Ash wood is one of the hardwoods that have a particularly high calorific value. Like beech wood, around 2,100 kWh can be produced from a meter of wood with ash wood. If you can get cheap ash wood for firewood, you have an excellent wood for heating.

Prices)

For lumber, the prices for ash wood can be quite different. Ash white is normally in the range of 900 - 1,100 EUR per m³, while the brown ash species usually only cost between 650 and 800 EUR per m³. The thermal treatment then makes sawn timber even more expensive, for these types of wood one has to start from prices in the range of approximately 1.700 - 2.200 EUR per m³.
