CNC Machining Materials

Material choice drives machinability, strength, corrosion resistance and cost more than any other decision. This page lists what we stock and machine daily, with guidance on when a grade is worth the premium and when a cheaper alloy performs just as well.

常见问题

常见问题解答

Which aluminium grade should I specify?

6061-T6 covers the large majority of parts with a good balance of strength, corrosion resistance and price. Move to 7075 when you need higher strength, and to 2024 for aerospace fatigue performance.

Is PEEK worth the cost?

PEEK is expensive but performs where nothing else does: high temperature, chemical exposure and sterilisation. If those are not in the requirement, POM or PPS usually delivers at a fraction of the price.

Can you machine from my material?

Yes. Send the grade and the stock form, or ship material to us and we will machine and return the remainder with the parts.
