Properties of Bilinga Wood

Bilinga wood is well-known for its striking appearance and robust physical properties, which make it suitable for a variety of applications. Here are some key physical attributes.

Density and Hardness: 

Bilinga wood is classified as a high-density hardwood, with an average density ranging from 850 to 1,050 kg/m³ (53 to 65 lb/ft³) when dried. This density contributes to its remarkable strength and durability, making it resistant to wear, dents, and scratches. 

Bilinga ranks high on the Janka hardness scale, with a measurement of 22.6 N (5,080 lbf), making it harder than many popular hardwood species like white oak and red oak.

Grain and Texture:

The grain pattern of Bilinga wood is typically interlocked or irregular, contributing to its distinctive appearance. Its texture is moderately coarse, with a uniform and consistent surface. The wood’s grain can be straight, wavy, or irregularly interlocked, adding to its visual appeal and uniqueness.

Color and Appearance: 

Bilinga heartwood ranges from a golden-brown to a reddish-brown hue, with darker streaks or blackish-brown marks often present. The sapwood is distinctly paler, ranging from a light yellow to a pale brown color. The wood’s distinctive grain patterns and color variations create a visually striking and attractive appearance, making it a popular choice for decorative applications.

Characteristics of Bilinga Wood

Beyond its impressive properties, Bilinga possesses distinct visual and working characteristics that influence its use:

Durability and Stability:

One of the most notable characteristics of Bilinga wood is its exceptional durability. It is highly resistant to fungal and insect attacks, as well as weathering and decay, making it an ideal choice for outdoor applications and construction projects.

Additionally, Bilinga wood exhibits good dimensional stability, minimizing the risk of warping, cupping, or splitting, even in environments with fluctuating humidity levels.

Workability and Machining: 

Despite its high density and hardness, Bilinga wood is relatively easy to work with and machine. It can be sawn, planed, turned, and sanded with reasonable ease, producing smooth and clean surfaces. However, due to its interlocked grain pattern, care should be taken during machining to avoid tear-out or rough surfaces.

Finishing and Gluing: 

Bilinga wood accepts a wide range of finishes, including stains, varnishes, and lacquers, allowing for a variety of aesthetic possibilities. It also glues well, making it suitable for lamination and joinery applications. However, proper surface preparation and the use of appropriate adhesives are recommended for optimal results.
