According to my research and personal experience, both alder and agathis are considered soft woods, but I believe alder is the harder of the two. But wood densities can vary greatly. Agathis is in the pine family, so it would stand to reason that it's soft. The alder wood guitar bodies that I own don't seem that soft to me! Hope that helps.
Wiring and electronics and wood the wood usually used is agathis basswood mahogany and alder p.s. fender's are better than Gibson.
Agathis wood is a fairly cheap wood useful for making all sorts of things. It's a general purpose wood. A tropical tree in the pine family, however it is not as soft as pine. It can be used to make musical instruments, however it is not the best wood for that purpose. Actually, it's not the best wood for making anything, but it could easily be used to make anything. It's a "universal" wood.
Yes, it is.
Agathis microstachya was created in 1918.
The botanical name for raja kayu wood is Agathis borneensis. It is a species of coniferous tree native to Southeast Asia.
A black alder is a variety of tree, Alnus glutinosa, of many practical uses, or the wood which grows on this tree.
maple is a different colour to alder and probably one will be stronger but im not sure

Mahogany or Alder.
Alder is fine as firewood. It burns fine but it burns fast as it is not a very dense wood. Denser woods burn hotter and slower.
They are flat boards, about the size of a shingle, that often get used to grill fish.
Yes.
