# Process Comparisons

8 head-to-head comparisons between manufacturing processes, each ending in a straight recommendation.

- [6061 vs 7075 Aluminum](https://manufacturingprocesses.org/compare/6061-vs-7075.md): 6061-T6 is the weldable, corrosion-resistant, easily anodized workhorse; 7075-T6 is roughly 85% stronger in tension but is not practically weldable and corrodes more readily.
- [CNC Machining vs 3D Printing](https://manufacturingprocesses.org/compare/cnc-machining-vs-3d-printing.md): CNC machining cuts a part out of certified wrought stock and holds tight tolerances; 3D printing builds it up layer by layer and charges nothing for geometric complexity.
- [Casting vs Forging](https://manufacturingprocesses.org/compare/casting-vs-forging.md): Casting melts metal and lets the mold define the shape, so almost any geometry is possible; forging deforms solid metal, so the grain follows the part and fatigue strength is higher.
- [Injection Molding vs 3D Printing](https://manufacturingprocesses.org/compare/injection-molding-vs-3d-printing.md): Injection molding pays for a steel tool up front and then makes parts for pennies; 3D printing has no tooling cost at all but a unit price that never falls with volume.
- [Investment Casting vs Die Casting](https://manufacturingprocesses.org/compare/investment-casting-vs-die-casting.md): Investment casting works in almost any alloy, including steel and superalloys, with modest tooling; die casting is limited to low-melting alloys but is far faster per part once the die exists.
- [MIG vs TIG Welding](https://manufacturingprocesses.org/compare/mig-vs-tig-welding.md): MIG feeds a consumable wire continuously and lays metal down fast; TIG uses a non-consumable tungsten electrode with separate filler, trading speed for control and weld appearance.
- [Powder Coating vs Paint](https://manufacturingprocesses.org/compare/powder-coating-vs-paint.md): Powder coating bakes a thick, tough, solvent-free film onto conductive parts; wet paint gives thinner films, unlimited color matching, and works on substrates that cannot go in an oven.
- [Sand Casting vs Die Casting](https://manufacturingprocesses.org/compare/sand-casting-vs-die-casting.md): Sand casting has almost no tooling cost and no size limit but a rough surface and loose tolerances; die casting inverts every one of those trade-offs.
