A 1 in x 6 in x 8 ft board of Goncalo Alves weighs about 17.7 lb (roughly 53 lb per cubic foot). Its Janka hardness of 2,170 lbf is harder than about 84% of the woods in our database.
Uses and working notes
Common uses: flooring, veneer, furniture, cabinetry, carving, turned objects, knife handles.
Durability: Very durable; weathers excellently and stands up to decay.
Workability: Manageable despite its density; figure troubles planing, cutters dull moderately, oils hinder gluing; finishes and turns well.

How these numbers were sourced
MOE, SG (12% MC), Janka and shrinkage from The Wood Database (cites USDA FPL Wood Handbook). SG given as a range; midrange value used. Not in the FPL/Hoadley dimensional-change table, so movement coefficients are omitted. Uses, region, durability, workability summarized from The Wood Database. Price indicative.
Values shown as estimates rather than sourced constants: typicalPricePerBF_usd, specificGravity.

These calculators are for planning and estimation. Engineering results (shelf sag, wood movement) use published average material properties; real boards vary by grade, grain, moisture and defects. Verify load-bearing designs with a professional.
