Hard Maple

  • Acer saccharum Marsh
  • English: Hard Maple, American Hard Maple
  • United States, Canada and Europe.

Description

&;8226; Sapwood: reddish white, very light.
&;8226; Heartwood: light red.
&;8226; Fiber: straight, occasionally wavy.
&;8226; Grain: thin-very thin.

Applications

&;8226; Interior furniture and cabinet work. Carved, turned and bent furniture.
&;8226; Hollow carpentry and paneling, interior : doors, platform, parquet flooring, friezes, molding.
&;8226; Decorative panels.

Capacity of being impregnated

&;8226; Sapwood: capable of being impregnated.
&;8226; Heartwood: low capacity of being impregnated.

Mechanization

&;8226; Sawing process: high potency is required.
&;8226; Drying process: easy and considerably slow. Risk of collapse, cementation and inside and outside crack formation.
&;8226; Planing process and other processes: risk of repelling appart from potency requirement problems.
&;8226; Gluing process: easy.
&;8226; Nailing and screwing process: pre-drilling is required in order to facilitate penetration and prevent breaks.
&;8226; Finish: easy

Physical properties

&;8226; Apparent density at 12% humidity 700 kg/m3 from semi-light wood to heavy wood.
&;8226; Dimensional stability
- Volumetric contraction coefficient 0.49 % nervous wood.
- Relation between contractions 2.06% tendency to deformity.
&;8226; Hardness (Chaláis-Meudon) 4.5 semi-hardwood.

Mechanical properties

&;8226; Resistance to static flexion 1,090 kg/cm2.
&;8226; Elasticity module 126,000 kg/cm2.
&;8226; Resistance to compression 540 kg/cm2.

Observations

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