Choose the material.
Then send the job.
Material drives CNC machining cost, lead time and what tolerances are realistic. Pick for the job first, then tell us what matters most. Here are the materials we machine most, and what a quote needs from you.
How we match material
We route each part to the shop in our vetted network best equipped for that material, so you get one quote and one point of contact. Your project manager confirms the grade fits the part before the quote goes out.

Missing something?
Send what you have. We’ll ask for the rest. One project manager owns the job from RFQ to delivery, so material and finish questions get settled before the quote goes out.
CNC materials questions
6061 is the default for prototypes and housings. It machines cleanly, anodizes well and costs less. Move to 7075 when the part needs higher strength, as in structural brackets or high-load fittings.
303 machines fastest, 304 is the general-purpose grade, and 316 holds up best in chlorides and marine service. Choose 17-4 PH when the part needs to be heat treated for strength + wear.
