yes tct blades cut ali with no problems as long as you take your time. Used one of these in the chop saw to ali http://www.ebay.co.uk/itm/250mm-Circ...item58b7e8d3eb at £9.50 I was a bit sceptical but it cut OK no good on wood as it burns and does not cut so well, like Dean said just fills the shop with smoke.
