JM - Tropical Wood

Massaranduba

Manilkara bidentata
Sapotaceae
When freshly cut the sapwood is light chestnut in color and the heartwood is a dark reddish brown. Once dry the sapwood turns light reddish brown and the heartwood become lighter in color.
The wood is very heavy and exhibits low linear contractions and moderately stable volumetric contraction. Although its high mechanical resistance and its hardness lower the wood’s overall workability, it responds well to brushing, drilling, turning, and molding. The wood’s natural drying is slow but it behaves well under artificial drying with a less severe schedule. It has high natural durability. The heartwood is resistant to biological attack but is susceptible to marine insects. The vacuum-pressure method is recommended for preservation.
The wood is used in sleepers, heavy construction, bridge elements, poles, floors, parquet, decorative arches, turning and musical instruments.
