Alder
The black alder is a tree that is widespread throughout Europe and is mainly found in loamy, damp locations such as swamps and rivers. Freshly cut wood has an orange-red hue that quickly darkens to a reddish-brown color. Perfect trunks are extremely rare, which means that alder often has flaws in the trunk.
The wood is notable for its fine, light, sometimes slightly reddish structure and color, which is dotted with brown inclusions and defects in the wood. It is used in instrument making, furniture making, box making, and as solid wood for construction. With a density of about 0.5 g/cm3, it is a medium-weight wood. It is flexible, soft, elastic, and strong.The advantages of alder are its good mechanical processing properties by hand and with machines, as well as its very good drying properties, without a tendency to crack or warp.
