You can buy some weapons for credits only, but they will not be supercharged. You can earn reactors to supercharge your weapon and warframe from ? alerts.

The weapons you can't buy with credits straight off require you to buy the blueprint and harvest the necessary materials from missions, bosses and alerts. The same applies to warframes. You can earn every warframe and weapon in game without having to pay a single cent. Only cosmetics, and I mean the colour pallette's not the helmets, have to be bought with cash money.
