( sorry for the forum flood, I have time for contraptor these few days )
What's the interrest of aluminium against other metals when choosing for something like contraptor ?
I'm asking because I can get :
- 1 meter of aluminium angle for 1,022 euros
- 1 meter of cold rolled iron angle for 0,643 euros
So the money concerns tell me to get iron, but something tells me aluminium was not choosen for nothing.
What are the inconveniences and advantages of each and why was aluminium choosen for contraptor ?
Edit : Also, in case this may be usefull to other metric folks, the website I'm planning to buy from ( delivers to France, Belgium and Netherlands ), it's the cheapest I found ( tell me if you find cheaper ) :
The website is leboutte.be
Google translation : Aluminium and Iron
Edit 2: I just saw this : http://www.contraptor.org/forum/t-202736/ , gives me a short answer, but I'd still be curious to know a more.
