.Yeah, i need like a sciency sounding answer.
Also, it isnt as prone to stress concentrations during welding, like many steel alloys are.
Its strength versus its weight is usually the reason people use it for partsDepending on the alloy, you can get aluminum that is good for higher strength applications like 7XXX, 5XXX and 6XXX are weldable, etc.
Titaniumsandwedge is correct, the weave entraps airIn addition, if you look at wool fibres under a microscope, it is somewhat jagged looking, so this also helps stop air movingThirdly, the wool fibre itself is a poor conductor of heatIf you have to talk about that for 10 mins, you had better repeat it over and over!
