Afzelia
kurz und knapp
Afzelia, especially the species Afzelia bipindensis, better known as Doussié Rouge, has been an outstanding imported wood from Africa for many decades. This wood species, which belongs to various species such as A. africana, A. bella, A. pachyloba and A. quanzensis, is valued for both structural and decorative purposes due to its excellent physical and mechanical properties, combined with high natural durability and attractive appearance.
Color and texture
The wood shows a yellowish-grey sapwood that is 3 to 10 cm wide, depending on age and species, and is clearly distinct in color from the yellowish to light brown heartwood. The color varies with the species, with A. africana and A. pachyloba becoming light reddish-brown and A. bipindensis and A. quanzensis copper-brown to dark reddish-brown. Natural wood characteristics such as gray or yellowish spots and irregular black veins may occur.
Charakter
Doussié Rouge präsentiert sich als gehobelt matt glänzendes, hell- bis dunkelrotbraunes Holz mit einer strukturreichen und dekorativen Oberfläche. Die Oberfläche ist attraktiv und verleiht dem Holz einen edlen Charakter.
Workability
Due to its great hardness, Afzelia requires the use of carbide-tipped tools for machining. Pre-drilling is required for nails and screws. The bondability is good to medium, and the surface treatment is primarily for color retention and moisture repellency.
Drying process
Afzelia dries slowly, so technical drying should be carried out gently and carefully. Sufficient conditioning time is recommended to minimize drying damage.
Natural durability
Afzelia is characterized by extraordinary resistance to wood-destroying fungi and insects, which makes it durability class 1 according to DIN EN 350.
Areas of application
The wood is particularly suitable for exterior construction with and without ground contact, especially in structural frame construction such as windows and doors. Indoors, Afzelia is used in high-quality parquet flooring and stairs due to its abrasion resistance and good durability.
Alternatives
Wood species such as Afrormosia, Jatobá, Iroko, Merbau and Moabi can serve as alternatives for replacement. Afzelia species native to Southeast Asia such as A. javanica, A. martabanica, A. rhomboidea and A. xylocarpa are also options.
Notes
Beachte, dass UV-Einwirkung zu fleckenförmigen Verfärbungsreaktionen führen kann, insbesondere im Parkettholzbereich. Kernholz fluoresziert gelblich unter UV-Licht, wobei A. bipindensis keine Fluoreszenz zeigt. Schleifstaub kann Schleimhäute reizen. Das Kernholz von Afzelia ist nicht auswaschbar mit Wasser.
