Canadian
White Hard Maple
(Acer saccharum)
APPEARANCE
Color: Heartwood is creamy
white to light reddish brown; sapwood is pale to creamy white.
Grain: Closed, subdued grain,
with medium figuring and uniform texture. Occasionally shows quilted,
fiddleback, curly or bird's-eye figuring. Figured boards often culled
during grading and sold at a premium.
Variations within species and grades:
Black maple is also hard; other species are classified as soft.
PROPERTIES
Hardness: 1450; 12% harder
than Northern red oak.
Dimensional Stability: Average
(change coefficient .00353; 4% more stable than red oak).
Durability: Dense, strong,
tough, stiff; excellent shock resistance - often used in bowling alleys
and athletic facilities. Markedly resistant to abrasive wear.
WORKABILITY
Sawing/Machining: Density makes
machining difficult.
Sanding: Sands satisfactorily.
Nailing: Fair resistance to
splitting; good holding ability.
Finishing: Takes neutral finish
well; does not stain uniformly. Comments: Light color lends itself to
contemporary light floors. Extra care must be taken during sanding and
finishing, as sanding marks and finish lines are more obvious due to maple's
density and light color.
