Has a straight to interlocked grain, with a medium to coarse texture. Good natural luster.
Diffuse-porous; large pores in no specific arrangement, few; solitary and radial multiples of 2-3; heartwood deposits present; narrow rays faintly visible without lens, normal spacing; parenchyma vasicentric,lozenge, winged, confluent, and marginal.
Rot Resistance :
Mora is rated as durable to very durable, and also has good resistance to insect attacks.
Pieces with interlocked grain can be difficult to work, frequently resulting in tearout during machining operations. Mora also has a pronounced blunting effect on cutting edges.
