Malayan Bintangor
Scientific name: Calophyllum wallichianum
Overview
Malayan Bintangor (Calophyllum wallichianum) is a tropical hardwood native to Peninsular Malaysia, southern Thailand, Sumatra, and Borneo. A member of the Calophyllaceae family, it is one of several commercially important species marketed under the trade name Bintangor. The species grows naturally in lowland tropical rainforests, where it develops large, straight trunks that provide quality timber for a wide range of woodworking applications.
The wood is valued for its attractive golden-brown coloration, moderate density, and reliable working characteristics. Throughout Southeast Asia, Malayan Bintangor has been used for furniture, cabinetry, interior millwork, veneer, paneling, flooring, and general construction. Although it is not as internationally recognized as Teak or Mahogany, it has earned a reputation as a dependable commercial hardwood that balances strength, stability, and ease of machining.
Freshly cut heartwood ranges from pale golden-brown to medium brown before gradually deepening in color with age and exposure. The grain is generally interlocked or slightly wavy, frequently producing attractive ribbon figure on quartersawn lumber. Combined with its moderate natural luster, these features make Malayan Bintangor suitable for both decorative and structural woodworking.
Within the Asian hardwood collection, Malayan Bintangor represents one of the principal Southeast Asian members of the Calophyllum genus and is an important representative of the commercially valuable Bintangor timber group.

Identification Characteristics
Malayan Bintangor is recognized by its warm golden-brown heartwood, moderate natural luster, and attractive interlocked grain. The sapwood is pale cream to yellow and contrasts clearly with the darker heartwood.
The wood has a medium texture with evenly distributed pores that produce a smooth, consistent appearance. Quartersawn lumber frequently displays ribbon figure resulting from the interlocked grain, while freshly machined surfaces exhibit an attractive natural sheen.
Key identification traits include:
- Golden-brown heartwood
- Cream to pale yellow sapwood
- Interlocked to slightly wavy grain
- Medium texture
- Moderate natural luster
- Ribbon figure on quartersawn lumber
- Distinct heartwood and sapwood contrast
- Good natural durability
Working Properties
Malayan Bintangor is considered an easy-to-machine hardwood that performs well with both hand and machine tools. While the interlocked grain may occasionally produce minor tear-out during planing, sharp cutters generally produce smooth finished surfaces.
The wood glues readily, sands easily, and accepts both stains and clear finishes exceptionally well. It also turns cleanly and develops an attractive natural polish suitable for quality furniture and decorative woodworking.
- Machines well

- Sands smoothly
- Accepts glue readily
- Finishes exceptionally well
- Develops an attractive natural polish
- Moderate dimensional stability
- Occasional tear-out in interlocked grain
Safety Note
Wood dust from Malayan Bintangor may cause skin, eye, or respiratory irritation in sensitive individuals. Proper dust extraction and respiratory protection are recommended during machining and sanding operations.
Common Uses

Sustainability & Notes
Calophyllum wallichianum grows throughout the tropical rainforests of Peninsular Malaysia, southern Thailand, Sumatra, and Borneo, where it contributes to some of Southeast Asia’s richest forest ecosystems. Like other members of the Bintangor group, it has long been harvested as an important commercial hardwood while also providing valuable ecological benefits within native forests.
Sustainable forest management, responsible harvesting practices, and internationally recognized forestry certification programs are increasingly important for protecting these forests. Purchasing responsibly sourced lumber helps support long-term conservation while ensuring that Malayan Bintangor remains available for future generations.
