cutting anodised aluminimum ?

[thetyreman]

I am making an acoustically sealed door, and have some door seals made from anodised aluminimum, what's the best way to cut them? they are made by zero international,

do I need a special blade? was thinking of using a chop saw, it has to be cut very accurately because a tiny gap and sound will leak through.

Blue bosch aluminium blade in the mitre saw.
Small cuts are super clean.
As the blade heats up you tend to get alloy left on the sides of the teeth and the cut begins to smear.

Lots of cleaning the blade between cuts helps. Wax lube probably does too, but I found out a bit late.
