6061 or 7075?
If your part doesn't carry much load, 6061-T6 is cheaper and anodizes better. If it needs strength, go with 7075-T6. Upload your file and we'll help you decide.

FAQ
About aluminum machining
- Which aluminum alloys do you machine?
- 6061-T6 and 7075-T6, the two alloys available in bar and plate in Monterrey. You choose them in the portal when you configure your part.
- What's the difference between 6061 and 7075?
- 7075-T6 is nearly twice as strong as 6061-T6, but it costs more, isn't welded, and its colored anodize is less even. If your part doesn't carry much load, 6061-T6 is cheaper and anodizes better; if it needs strength or it's a mold or tooling, go with 7075-T6.
- What finishes can you apply to aluminum?
- Type II anodizing in clear, black, gold, red, blue, violet, turquoise, and olive drab; Type III hard anodizing; chemical conversion (trivalent or chrome-free); bead blasting; brushing; powder coating; and nickel plating. It can also go as machined, with no finish.
- Does anodizing change the dimensions?
- Yes, slightly: anodizing builds up from the surface, and Type III builds up more. On tight dimensions, fit holes, and threads it's accounted for in the design or those areas are masked so they aren't anodized.
- What tolerances can you hold in aluminum?
- By default, ISO 2768-m general tolerances apply. On the dimensions you specify on your drawing we can hold ±0.025 mm, and critical dimensions are verified at inspection.
- Can I order a single part?
- Yes. There's no minimum quantity: you quote from 1 part, and the quote shows how the price per part drops with more quantity.
- Do you provide a material certificate?
- Yes, on request. When you configure your part, mark that you need a material certificate and traceability, and it ships with your order.
CNC machining of 6061 and 7075 aluminum
Aluminum is the most machined metal: it weighs a third of steel, doesn't rust like it, conducts heat well, and cuts fast, so an aluminum part usually costs less than the same part in steel or stainless. That's why it's used for brackets, housings, base plates, fixtures, prototype molds, and automation parts.
6061-T6 is the general-purpose alloy: good strength, excellent machinability, and it welds and anodizes very well. It's the default choice when the drawing doesn't call for something else. 7075-T6 is the high-strength alloy: nearly twice as strong as 6061, which is why it's used in molds, tooling, heavily loaded parts, and aerospace; it costs more, isn't welded, and its anodize color comes out less uniform.
Anodizing is aluminum's natural finish: an oxide layer that protects against corrosion and wear. Type II can be dyed (clear, black, red, blue, gold…) and Type III (hard) is thicker and more wear-resistant. Note: anodizing adds material, so tight dimensions and threads are accounted for from the design stage.
