- Black Ironwood – 84.5 lbs/ft.

- African Blackwood – 79.3/ft.
- Lignum Vitae – 78.5 lbs/ft.
- Quebracho – 77.1 lbs/ft.
- Leadwood – 75.8 lbs/ft.

Which trees are diffuse-porous?
In diffuse-porous woods the pores are scattered throughout the growth ring instead of being collected in a band or row. Examples of this kind of wood are basswood, birch, buckeye, maple, poplar, and willow.
What is the unit weight of wood?
With the specific gravity around 1.5, solid wood “substance”, or lignocellulose as it is commonly called today, weighs around 1500 kg/m3 (93.6 lb/ft3), at theoretical most… no air, water, or other fluids in cell pores, which would decrease the weight of the wood per unit of volume.
Which wood is most porous?
In some species (e.g. oak and ash), the largest pores are in the earlywood while those in the latewood are more evenly distributed and uniform in size. These woods typically have distinct figures and patterns, and the uneven uptake of stain (the large pores soak up more color) make the figure more pronounced.
Which wood is heavy?
The densest of all woods is Allocasuarina luehmannii. Krugiodendron typically has a higher density, among many other woods that vary by sample. Various other hardwoods may also be called lignum vitae and should not be confused with it.
What wood is heavier than oak?
Not All Trees Are Equal Especially dense examples of red and southern yellow pine are actually denser and heavier than the average sample of red oak. Of course, oaks also produce trees that are sometimes denser than average, but sometimes an especially robust, dense pine is heavier than oak.
Is Black Walnut diffuse porous?
Black walnut is a semi-ring porous wood, but it can also be correctly called a semi-diffuse porous wood. Figure 8-4. similar-sized pores scattered throughout the rest of the growth ring. (Because the pores in black cherry are mostly about the same size, some authors describe this as a diffuse porous species.)
What is diffused porous wood?
In most of the gymnosperms, like conifers and cycads, vessels are absent and the wood is made entirely of tracheids. In porous wood, if vessels have essentially equal diameters and are uniformly distributed throughout the ring, the wood is known as diffuse porous. It is characterstic of plants growing in tropics.
How do you calculate the weight of wood?
A: Calculate weight, Mike, using the formula: density × volume. Well-dried, seasoned oak has of a density of about 3.6 pounds per board foot. Now find the board footage of your lid by multiplying its length, width, and thickness, and dividing by 144.
How heavy is a log of wood?
board feet of Doyle scaled logs can weigh, on average, from 15 to 5 tons for log (scaling) diameters from 8 to 20 inches, respec- tively (Table 3). However, even for logs of the same diameter, weights for individual logs can range plus or minus 40 percent of the average value.
What is diffuse porous wood?
In most of the gymnosperms, like conifers and cycads, vessels are absent and the wood is made entirely of tracheids. In porous wood, if vessels have essentially equal diameters and are uniformly distributed throughout the ring, the wood is known as diffuse porous.
Is Pine a porous wood?
When referring to wood, most softwoods, such as pine, cedar and redwood, are non-porous. Non-porous woods do not have as many vessels within the wood fibers. Non-porous woods are typically softwoods, including those from conifer trees.
What kind of wood is semi ring porous?
In some species (e.g. black walnut and butternut), pores are large in the earlywood and smaller toward the latewood, but without the distinct zoning seen in ring-porous woods. Also, some species that are usually ring-porous (e.g. cottonwood) occasionally tend toward semi-ring porous.
What kind of wood has small diameter pores?
Most domestic diffuse-porous woods have relatively small-diameter pores, but some tropical woods of this type (e.g. mahogany) have rather large pores. These woods usually have even uptake of stain (there seems to be no scientifically proven explanation of the cause of blotching). These are also known as closed-grain woods.
How does ash affect the weight of wood?
Ash, which makes up 0.5% to 2.0% of most woods, has a specific gravity of 1.6 to 2.8; the specific gravity of extractives varies depending on the substance. Together, the amount of ash and extractives in wood can vary from trace amounts to 30% and therefore affect the weight of wood differently according to species. 1
How much does a piece of wood weigh?
With the specific gravity around 1.5, solid wood “substance”, or lignocellulose as it is commonly called today, weighs around 1500 kg/m 3 (93.6 lb/ft 3), at theoretical most…no air, water, or other fluids in cell pores, which would decrease the weight of the wood per unit of volume.
