Hard Maple (Sugar Maple, Acer saccharum)

diffuse-porous hardwood, closed-grain · sugar maple, rock maple, Acer saccharum

The wood of bowling alleys, butcher blocks, basketball courts, and kitchen cabinets. Pale, dense, even-grained, no strong figure unless figured selections are picked (curly, birdseye). Takes wear that would dent oak. Glues and finishes cleanly.

Diffuse-porous hardwood with very fine, evenly distributed pores. Janka hardness ~1450 lbf — among the hardest North American commercial hardwoods. Dense enough to dull tooling that handles oak fine. Common for cutting boards, gym flooring, instrument bodies.

CNC milling on swarf

The hardest of the standard furniture hardwoods. Mills cleanly but tools dull faster than on softer woods — keep spares sharp. Excellent for cutting boards, butcher blocks, fine furniture; takes a near-glass-smooth finish off the bit.

Second life

repairabilityhigh — common cutting-board / butcher-block resurfacing is annual maintenance; furniture-grade repairs use the standard fill-and-finish techniques.
recyclabilitymoderate — solid stock reusable; mulch / energy recovery at end of life.
disposal pathcompost / mulch.
typical longevity150 years (typical)
failure modes
  • surface cracking on butcher-block surfaces from oil starvation
  • drying checks in unstable humidity
  • low rot resistance — not for exterior service
