Moderate


Tree Identification
Bole/stem form is not buttressed
Bole/stem form is cylindrical


Tree Size
Sapwood width is 5-10 cm


Termite attack common in larger trees. Tend to split severly when felled.

Substitutes
Balearic boxwood

(B. balearica ), and Cape boxwood (B. macowani ), both from South Africa. Also

Comments
General finishing qualities are rated as good

Serrette is slightly stronger than European beech (Fagus ).

Unsuitable for plywood manufacture

Blunting Effect
Blunting effect on sawing dry wood is moderate
Blunting effect on machining is moderate

The wood has moderate dulling effect on tool edges.

Boring
Wood can char during boring operations


Cutting Resistance
Satisfactory sawing properties
Cutting Resistance with dry wood is easy


Movement in Service
Medium


Nailing
Pre-boring recommended


Planing
Good planing properties


Resistance to Impregnation
Heartwood is moderately resistant
Sapwood is moderately resistant


Resistance to Splitting
Poor


Response to Hand Tools
Easy to machine


Screwing
Possible if prebored
Difficult to screw


Veneering Qualities
No drying degrade. Dries flat without splitting
Diifficult to veneer


Steam Bending
Variable steam bending qualities
Moderate

Recommended for bends of only moderate radius of curviture

Strength Properties
Modulus of Elasticity (stiffness) = medium
Max. crushing strength = high
Hardness (side grain) = medium
Bending strength (MOR) = medium
Shearing strength (parallel to grain) = medium
Bending strength (MOR) = high
Toughness-Hammer drop (Impact Strength) = low
Shrinkage, Volumetric = moderate
Shrinkage, Volumetric = large
Shrinkage, Tangential = fairly large
Shrinkage, Radial = small
Max. crushing strength = medium
Hardness (side grain) = soft
Density (dry weight) = 53-60 lbs/cu. ft.
Density (dry weight) = 46-52 lbs/cu. ft.

Species has very high bending strength, and is much stronger than Teak in the air-dry condition (about 12 percent moisture content). Maximum crushing strength, or compression parallel to grain in the air-dry condition, is in the very high range. It is stronger than Hard maple, White oak, or Teak. It is moderately hard and resistant to wearing and marring. It is a heavy wood. The wood has high density.
