What are the properties of hard wood?

Characteristics of Hardwood

  • They usually have a higher density than softwood.
  • They are usually more expensive than softwood.
  • They grow at a slower rate than softwood.
  • Hardwood trees shed their leaves in certain times of the year.
  • Hardwood are more fire resistant than softwood.
  • The leaves of hardwood trees are evergreen.

What are the 4 properties of hardwood?

The hardwoods have a specific gravity ranging between 0.7 to 0.9 whereas in most of the softwoods it lies below 0.7. Hardness and strength of wood depend to a great extent on its density….Properties of Timber and Wood.

What are 3 characteristics of hardwoods?

Different species of hardwood lend themselves to different end uses or construction processes. This is due to the variety of characteristics apparent in different timbers, including density, grain, pore size, growth and fibre pattern, flexibility and ability to be steam bent.

What are two characteristics of hardwood?

The Difference Between Softwood And Hardwood

Characteristic Hardwood Softwood
Examples Oak, Teak, Mahogany Pine, Spruce, Fir
Price More expensive Less expensive
Density Typically harder (but not always) Usually softer (but not always)
Colour Generally dark Almost always light

What are the 12 properties of wood?

The mechanical properties of wood considered in this book are: (1) stiffness and elasticity, (2) tensile strength, (3) compressive or crushing strength, (4) shearing strength, (5) transverse or bending strength, (6) toughness, (7) hardness, (8) cleavability, (9) resilience.

What are the 5 physical properties of wood?

The main physical properties of wood include: color, luster, texture, macro-structure, odor, moisture, shrinkage, internal stresses, swelling, cracking, warping, density, sound – electro – thermal conductivity.

What are the main physical properties of steel?

Basic Physical Properties of Steel Steel has a density of 7,850 kg/m3, making it 7.85 times as dense as water. Its melting point of 1,510 C is higher than that of most metals. In comparison, the melting point of bronze is 1,040 C, that of copper is 1,083 C, that of cast iron is 1,300 C, and that of nickel is 1,453 C.

What are the properties of wood?

The main physical properties of wood include: color, luster, texture, macro-structure, odor, moisture, shrinkage, internal stresses, swelling, cracking, warping, density, sound – electro – thermal conductivity. Сolor, shine, texture and macrostructure determine the appearance of wood.

What are the properties and uses of wood?

The mechanical properties of wood include strength in tension and compression (as measured in axial and transverse directions), shear, cleavage, hardness, static bending, and shock (impact bending and toughness).

What are the main differences between hardwood and softwood?

The main difference between hardwood and softwood is that hardwood trees are typically slower growers and are considered angiosperm, deciduous trees (shed their leaves annually), which leads to a denser wood, whereas softwood trees are gymnosperms, meaning they are evergreen trees (do not shed their leaves).
