I am having a hard time placing Khaya/African mahogany. An article states:
Varieties of mahogany include Honduran, South American, Peruvian, Bolivian, Cuban, Big Leaf and True. All of them are typically marketed together and sold as "genuine mahogany." Two other varieties differ slightly: African mahogany, because of its luster and hardness, is considered superior to genuine mahogany and is usually marketed separately from genuine. (source)
However, this seems to be belied by the actual numbers. Per The Wood Database African mahogany's Janka Hardness is marked "1,070 lbf (4,760 N)" which is not particularly high. I know there are mahogany varieties with lower numbers, but I don't think 4,760 N makes the timber impressive flooring material. This site gives a wide density range (0.5 – 0.85 1000 kg/m3)
What, more accurately, is African mahogany's density? I am very concerned about its durability and scratch resistance properties. How does it fare as flooring? What are other notable qualities of this timber?
