Hard Maple

Scientific name: Acer saccharum Marsh

Geographic origin: United States, Canada and Europe.

Description

  • Sapwood: reddish white, very light.
  • Heartwood: light red.
  • Fiber: straight, occasionally wavy.
  • Grain: thin-very thin.

Capacity of being impregnated

  • Sapwood: capable of being impregnated.
  • Heartwood: low capacity of being impregnated.

Mechanization

  • Sawing process: high potency is required.
  • Drying process: easy and considerably slow. Risk of collapse, cementation and inside and outside crack formation.
  • Planing process and other processes: risk of repelling appart from potency requirement problems.
  • Gluing process: easy.
  • Nailing and screwing process: pre-drilling is required in order to facilitate penetration and prevent breaks.
  • Finish: easy

Physical properties

  • Apparent density at 12% humidity 700 kg/m3 from semi-light wood to heavy wood.
  • Dimensional stability
  • - Volumetric contraction coefficient 0.49 % nervous wood.
  • - Relation between contractions 2.06% tendency to deformity.
  • Hardness (Chaláis-Meudon) 4.5 semi-hardwood.

Observations

Its main difference with the soft maple is its colour, sugar maple has a bright white colour.
