Tali

Scientific name: Erythopleum utile Sprangue; E. Suaveolensis Brenan

Geographic origin: Africa

Description

  • Sapwood: Yellowish white to pinkish white, clearly distinct
  • Heartwood: yellowish gery to reddish grey
  • Fiber: Straight, frequently intertwined or very intertwined
  • Grain: Slightly/occasionally interlocked to highly/frequently interlocked

Capacity of being impregnated

  • Sapwood: Medium capacity of being impregnated
  • Heartwood: Low capacity of being impregnated

Mechanization

  • Sawing process: ordinary difficulties arise from hardness
  • Drying process: very slow. High risk of deformation and lower risk of crack formation
  • Planing process: Difficult due to its hardness and to the risk of repelling and splinting. Slow mechanisation is highly recommended
  • Gluing process: Tannins hamper proper adherence
  • Nailing and screwing process: pre-drilling is recommended due to the hardness
  • Finish: Rubber deposits can locally inhibit varnish adherence

Physical properties

  •  Apparent density at 12% humidity 920 kg/m3 very heavy wood
  • Dimensional stability
  • - Volumetric contraction coefficient 0.52%. It varies from nervous wood to very nervous wood
