Hardness/Janka: Janka:1820; (41% harder than Northern red oak). Pecan is slightly softer than true hickories.
Dimensional Stability: Pecan, average (8.9; 3% less stable than Northern red oak.
Sawing/Machining: Hickory’s density makes it difficult to machine and work with hand tools.
Nailing: Has a tendancy to split the tongues.
Sanding: Difficult to sand because of density, and because light color makes sander markers show more than on darker woods.
Finishing: May be difficult to stain
