They are most common in the Amazon basin, and are also found in Colombia, Guyana, Surinam, and Venezuela. Heartwood Color Brown Yellow Orange Green/grey Purple Black Red Purple Dark brown The heartwood is initially dull brown, but it rapidly changes to a bright, vibrant purple. Prolonged exposure darkens the wood to a dark-purplish brown or dark brown, but the original color can be restored by recutting the wood. Color variation between boards is moderate to high. Presence of minerals in some boards may cause uneven coloration and steaming is reported to affect the color. Peltogyne timbers are reported to vary widely in color between, and probably within, species Sapwood Color White Yellow Brown Red Green/Grey White to yellow Well defined Off-white Creamy white Clearly differentiated from the heartwood The color has also been described as pinkish cinnamon with light brown streaks, and is usually about 2 to 4 inches (5 to 10 cm) wide. Grain Figure Stripe (figure) Straight Interlocked Even Closed Other (figure) Distinct (figure) Striped figure Straight Interlocked Other figure Distinct figure The grain is typically straight, sometimes wavy, roey, or irregular Texture Fine Medium Fine to medium Medium Fine Luster Medium High Pronounced Medium to high Lustrous Natural Durability Very durable Resistant to termites Susceptible to insect attack Resistant to marine borers Durable Resistant to powder post beetles Non-resistant to powder post beetles Very durable Durable Resistant to attack from termites (Isoptera) Very resistant to dry-wood termite attack Susceptible to marine borer attack Slightly resistant to attack by marine borers Resistant to attack from powder post (Lyctid & Bostrychid) beetles Highly resistant to attack by decay fungi The wood is also resistant to chemicals such as acids Odor Has an odor No specific smell or taste Toxicity Some toxic effects Kiln Schedules UK=E US=T6D2/T3D1 Fr=5 Dry at a slow speed Drying Defects Distortion Slight twist/warp Slight surface checking Moderate twist/warp Expect resin/gum exudation Slight end splitting Severe end splitting Ease of Drying Fairly Easy Slowly Variable Little degrade Moderate Difficult Variable results. Difficulty in air-drying varies from easy to moderately difficult, and drying rate ranges from slow to fairly rapid. Moisture extraction from center of thicker stock is rather difficult Kiln Drying Rate Naturally dries slowly Slow Drying rate is slow Tree Identification Bole/stem form is buttressed Tree Size Sapwood width is 0-5 cm Trunk diameter is 100-150 cm Tree height is 30-40 m Trunk diameter is 150-200 cm Tree height is 20-30 m Trunk diameter is 200-250 cm Mature Purpleheart trees are usually tall and attain a height of about 100 to 150 feet (30 to 45 m), and a diameter of up to 48 inches (120 cm), usually between 18 and 36 inches (45 and 90 cm). Product Sources The ITTO reports that timber production from this species is regular. The material is exported at a low but regular rate. Supplies are ample, but the wood is fairly expensive. It costs more than mahogany but less than teak. Although it has not found wide demand, Purpleheart is available on the US market in both the lumber and veneer forms. Certified Source Certified Source Comments General finishing qualities are rated as good Treatment against the effects of ultra-violet rays has been suggested to maintain the original color of the wood. A treatment with Armorall, the car finish product, under lacquer is reported to hold the color well Working the wood with dull cutting tools may cause gum exudation Blunting Effect Moderate Blunting effect on sawing dry wood is moderate Blunting is rated as moderate to severe Blunting effect on machining is fairly severe Cutting tools may be gummed up if they are not very sharp Boring Fairly easy to very easy Fair to good results Easy Carving Fair to Good Results Fairly Easy to Very Easy Cutting Resistance Easy to saw Cutting resistance with dry wood is variable Tools usually require frequent sharpening Slow feed rates and specially tipped cutters are suggested Moderate to fairly difficult to saw Gluing Fairly Easy to Very Easy Fair to Good Results Easy to glue Mortising Fair to Good Results Fairly Easy to Very Easy Moulding Fair to Good Results Fairly Easy to Very Easy Movement in Service Excellent Stability - Small Movement Small Dimensionally stable Nailing Fairly Difficult to Very Difficult Fair to Good Results Pre-Boring Recommended Pre-boring recommended Holds nails well Planing Fairly Easy to Very Easy Fairly Difficult to Very Difficult Fair to Good Results Ease of planing is moderate Respond poorly to ordinary tools Moderately difficult to work in most machining operations Working with dull cutters may cause the wood to heat up and exude resin, which can considerably increase machining difficulty. Slower feed rates and specially tipped cutters, or sharp, high-speed steel knives are suggested. A reduced cutting angle of 15 degrees has also been recommended, especially when planing and moulding material with interlocked or wavy grain.
