It is popular for both residential and commercial construction applications, including luxury decking, furniture, flooring, and structural applications.
If you’re looking for a reliable hardwood that combines attractive appearance with good physical properties, Cumaru is a great option. At AtoZ Wood Company, we supply premium-quality, FSC-certified Cumaru timber to builders, furniture manufacturers, timber merchants, and homeowners worldwide. This article explores the properties, types and applications of Cumaru wood to help you choose the best timber for your project.
What is Cumaru Wood?
Cumaru is a tropical hardwood harvested primarily from Northern South America, particularly Brazil, Peru, Colombia, and Bolivia. Also called Brazilian Teak, it comes from Dipteryx odorata trees in the Fabaceae plant family and stands out for its durability and attractive appearance. However, cumaru is not related to true teak. It is also often used in place of Lignum Vitae, which is a much harder and rarer species.
Cumaru hardwood features a rich golden-brown to reddish-brown hue with darker, prominent grain patterns that become even more attractive after finishing or with age. Its natural hardness and oils make it highly resistant to everyday wear, decay and weather conditions, making it suitable for both indoor and outdoor applications.
Properties of Cumaru Wood
Cumaru is cherished for its combination of timeless beauty and exceptional mechanical strength. Key properties include:
Excellent Hardness
Cumaru is one of the hardest commercial hardwoods in the market. Its high density makes it naturally resistant to dents, scratches, and general everyday wear, making it one of the best choices for high-traffic areas.
Outstanding Durability
Cumaru naturally offers excellent resistance to decay, termites, moisture, fungi, and wood-borers. It handles harsh weather conditions exceptionally well, making it suitable for outdoor use.
Attractive Appearance
Cumaru’s rich brown color, natural dark streaks and interlocked grain give it a premium appearance that suits both modern and traditional styles perfectly.
High Density
Cumaru’s high density provides excellent structural strength and wear resistance. However, this can present difficulty when cutting, drilling, or installing.
Natural Fire Resistance
Cumaru has a high natural resistance to fire, making it a preferred material for commercial and industrial projects.
Workability
Cumaru’s interlocked grain and presence of oils and silica can make it difficult to work with and often dull cutters.
Types of Cumaru Wood
Based on the source, color, grain, and properties, Cumaru can be divided into the following types:
- Red Cumaru: The most common variant. It features a rich reddish-brown tone with darker streaks and is extensively used for premium flooring, furniture, decorative interiors, and outdoor construction.
- Yellow / Golden Cumaru: It has a lighter, golden-brown tone that gives a bright, clear look to a project. It is ideal for decking, cladding, and flooring.
- Select Grade Cumaru: This is a premium-quality product containing minimal knots, uniform color, and striking grain patterns. It is commonly favored for luxury interiors, premium flooring, and furniture.
Common Uses of Cumaru Wood
The stunning color tone, remarkable strength and natural weather resistance of Cumaru make it suitable for a wide range of applications.
Outdoor Decking
Cumaru, particularly Yellow Cumaru, is an excellent choice for outdoor decking due to its long service life, natural resistance to moisture and insects, and ability to handle heavy foot traffic. Properly installed and maintained Cumaru decks can easily last decades.
Hardwood Flooring
Its impressive hardness and stunning dark color tone make Cumaru an excellent choice for both commercial and residential flooring, especially when durability is essential.
Furniture
Cumaru is an excellent choice for making premium-looking, durable furniture, tables, benches and chairs for both indoor and outdoor use. Its natural resistance to insects and climate conditions makes it a favorite.
Exterior Cladding
Cumaru is often the first choice for exterior wall cladding because of its rich appearance and resistance to changing weather conditions. It requires minimal maintenance.
Outdoor Construction
The strength and durability of Cumaru make it suitable for outdoor structures including pergolas and gazebos.
Marine and Waterfront Projects
Because of its excellent natural resistance to moisture, Cumaru is highly favored for docks, boardwalks, ports, ships and waterfront construction.
Staircases and Interior Joinery
Its elegant color tone and grain pattern make Cumaru a wonderful choice for interior woodworking, staircases, handrails, doors, cabinets and decorative projects.
