Standard copper tubing isn't used for vehicle A/C lines (nor fuel lines) due to its poor fatigue life in the vibration environment - it work hardens and cracks plus it is heavy for it's pressure rating. Doc's Bloc's sells the standard sizes of 3003 aluminum refrigeration tubing in coils and straight lengths, plus an assortment of braze-on fittings (propane torch), braze alloy (including handy pre-formed rings for fittings), compressor flange blocks, etc.
