* Janka Hardness: This measures the force required to embed a steel ball into the wood. This is the most common measure used for comparing wood hardness.
* Brinell Hardness: This measures the indentation made by a hardened steel ball pressed into the wood.
Here are some of the top contenders for "hardest woods" based on Janka hardness:
Top 10 Hardest Woods (Janka Hardness)
1. Australian Buloke (Allocasuarina luehmannii) - 28,200 lbf
2. Quebracho (Schinopsis balansae) - 27,600 lbf
3. Yate (Eucalyptus cornuta) - 26,900 lbf
4. Australian Blackwood (Acacia melanoxylon) - 25,200 lbf
5. Teak (Tectona grandis) - 23,800 lbf
6. Ironwood (Mesua ferrea) - 23,600 lbf
7. Purpleheart (Peltogyne pubescens) - 22,600 lbf
8. Ipe (Tabebuia impetiginosa) - 21,800 lbf
9. Tigerwood (Sclerolobium densiflorum) - 21,700 lbf
10. Brazilian Walnut (Juglans brasiliensis) - 21,500 lbf
Important Note:
* This list is based on Janka hardness measurements and may vary depending on the source.
* It's also important to note that wood hardness is not the only factor to consider when choosing wood for a particular application. Other factors like durability, workability, and resistance to rot and insects are also important.
