Pear tree – Bolivian – Peroba Rosa

Names and distribution:

Botanically, the species (Aspidosperma cylindrocarpon) belongs to the Apocynaceae. The tree species is known as Jichituriqui in its country of origin, Bolivia, and is related to Peroba Rosa (A. peroba, Brazil). The distribution is limited to the humid forests of Bolivia, where Jichituriqui is relatively common.

Wooden picture:

The heartwood has a salmon-colored, pinkish-red tinge, reminiscent of European wood. Birnbaum reminds us. The sapwood is light yellow and clearly set off from the heartwood. The pink color develops into light brown in the light over time. Jichituriqui, like pear tree, has fine pores, the grain is often straight, sometimes twisted. Growth ring-like growth zones are recognizable, overall appearance similar to that of pear tree, inconspicuously homogeneous, due to the discreet wood structure overall a decorative precious wood. Less rose-colored than pear.

Properties:

The density at 12% wood moisture is approx. 0.75 – 0.80 ^t/m3. The volume shrinkage from juice fresh to 12% is 13.9%, the tangential shrinkage is 6.7% and the radial shrinkage is 5.5%. Wood is comparable to maple in terms of its swelling and shrinking properties. The machinability is good (planing, milling, nailing) and can be polished well. The Brinell hardness is 38 (in comparison: europ. Oak 34 N/mm2. The modulus of elasticity is given as 13,000 ^N/mm2 and the bending stiffness as 119 ^N/mm2.

Use:

Parquet flooring, wood-turned goods, musical instruments, etc.
