Most people say green tungsten (pure tungsten) and ball the end for aluminum.Others say to use 2% thoriated(red) or lanthanated tungsten ground to a point and add a flat spot to the end.I haven't welded aluminum much yet so I can't tell you which is better.
It depends ,to a large degree, on what type of machine you are using. (inverter,transformer etc..) Then it would be by preference.

not green(pure).
red(thoriated), gold(lanthanated) or orange(ceriated) are your best bets. I like the lanth the best, it seems to last longer. I never had starting issues with any of them as long as the tungsten was clean and well-sharpened. if you're on a modern tig machine (either square wave transformer or inverter), point the tip like you would for steel, but take a small land off the end. that point has a habit of burning off into your weld. make sure that land is perpendicular to the tungsten, too, or the arc will always start off the longer side of the land.

I have a dynasty and have tried red and dark blue. The dark blue 2% lanthanated works or holds up the best for me . I sharpen it like I would for steel and put a flat land on the tip. the red 2% thoriated will work in a bind but splits and spits too much for a critical weld.

Try getting your hands on Zirconiated, they have a white end. They were designed just for alloy welding, big in Aus over here but almost unheard of over there in the states. I have a decent machine with water cooler and can run as high as 145amps on a 2.4mm Zirc electrode without problems.
Give'em a go.
Cheers

Pure tungsten is pure crap. Balling sucks too.
Go with lanthanated. Rounded tip.
I would love to try the zirconioated.
Hmm, just checked, zirconiated is available in the US and it is color coated 'brown'

Welding everything from the crack of dawn to a broken heart.
Ive played around with different tugstens and have found that the 2% lanthinatied works best for me.
