Speed of the blade. Rigidity of the frame. Unless your thinking of the difference between horizontal bandsaws and vertical bandsaws (you can get both types for both materials)
Metal cutting blades need to be ran much slower than for wood, although aluminium can be done higher...
If your thinking about buying a oldie thats built like a tank, you could always fit a vfd (variable frequency drive) to it, or gear it down with some pulleys...
Bidding on a 1932 bandsaw myself at the moment, and plans are change the gearing, and put a vfd on it...

And outbid,someone went to 700e for a rusty saw, the other 5 recent examples of which went for 300e, by a uk account who hasnt traded in 2 years and who failed to follow through on his last two wins.

Speed is fast on a steel aluminium and wood saw
stainless is slower
you use fine teeth for steel and stainless corse for aluminium and wood

I thought steel was much slower than aluminum...
For green wood, you would run 3200 SFM or thereabouts cutting speed, but dependant on what the blade manufacturer recommends of course...
Great write up on saws and stuff...

The real problem with wood bandsaws, is they are designed to spin at speeds which generate 2000+ sfm and will not slow down enough to steel speeds.

My machine is direct drive not belt driven meaning I only have 2 speed on my saw fast for most things and slow for stainless and other hard materials I Knew the softer the material the corser the teeth and the faster you ran it but I had not realised how much faster.
other rules ou can work on dependant on quality of saw is the thicker the material the courser the blade can be I use varipitch blades (4/6) TPI for all round steel as we do not tend to cut thinner than 3mm thick I have run 2 TPI on billit work. as the saw I have is well built and rugid. on a small saw with steel the pitch wants to allow 2 teeth in the thinnes part of the material at any time work on tip to tip being 2/3 of the the material thickness.
Yes a wood saw will be to fast.
