Why don't they anodize aluminum bikes? It would looks so much better than stupid paint and it won't chip.

they used to but it doesnt protect as well as paint

>>2047569
how so?

>>2047570
how about corrosion

>>2047571
aluminum isn't corrosive.

>>2047572
Aluminum does corrode just so much slower than steel that it's sometimes not considered a factor however different aluminum alloys have different corrosion attributes and some alloys don't have as strong corrosion resistance in certain galvanic situations

Also, they did and still do, the problem is cost and time, paint is cheaper, faster, and consistent

>>2047566 (OP)
My Cube's frame, circa 2013, is anodized. It feels nice, it looks premium, and it's indeed super durable.
But consistent anodizing on such a large part is expensive and difficult, even mine has a few blemishes. They probably quit doing it because of the defect rate.
Also, carbon is all the rage now, and giving people an excuse to go with a cheaper aluminium model just for the cool finish is counterproductive to the business side of things. You will buy a carbon frame painted black and you will be happy about it.

Annodizing is super thin and wears off easily
its also labor intensive where you have to hyper clean parts
with the paint they use on bikes they only need to get it fairly clean

>>2047593
The difference between anodizing and painting is that paint is on top of the part while anodizing is embedded into aluminium's oxide layer. So yes, anodizing is thin, no, it doesn't mean it wears off easily. You most likely have anodized parts on your bike, cranks in particular are commonly anodized and face a lot of rub action through their lifetime.

LMAO
aluminium is TURBOCORROSIVE
KEK

>>2047616
alu is so damn corrosive it loops back around and becomes almost inert
its surface instantly oxidizes in the air and protects the rest of the metal

t.retard

>>2047627
no shit sherlock. But that is under very specific conditions only and very very quickly goes complete trainwreck.
Long story short, im not looking to be bored with retard takes itt:
They don't because it offers relatively weak corrosion protection compared to. paint. You can get that by just painting clear over it as it's the etch primer that makes the paint a very durable solution that offers good protection.
Idk why but /n/ is just always very bad when it comes to material science and other engineering topics even when its just trivial knowledge.

>>2047616
>>2047657
Is that why they made the cap on the Empire State Building out of raw aluminum?

>>2047747
So that jet fuel can’t damage it

Trek's the only one I know that does that. It's from their ProjectOne line of paintjobs.

>>2047875
I remember buying faded anodized paintball guns that cost like $5k. Those were the days.
