This aluminum alloy is cast specifically for applications that require highly accurate components like assembly jigs, test structures, and fixture plates. It is well-suited to these applications because its crystal structure has no internal stresses. It also allows for high-speed machining without the significant distortion common in other aluminum alloys.

Cobalt drill bits are best suited for use on hard to machine metals, including hardened or stainless steel. Cobalt is blended in with High Speed Steel to make the drill bits harder and more wear resistant. As each cobalt drill bit consists of High Speed Steel with a small percentage of cobalt, the higher the percentage of cobalt, the more heat-resistant and durable the drill bit is.

Aluminum is very easy to machine, but it’s abrasive, so cutting tools will tend to wear quickly. The best drill bits for aluminum are solid carbide because solid carbide is very hard and stays sharp much longer than other materials, providing extended tool life. If you’re only poking a few holes, high speed steel (HSS) is fine. Using a cobalt drill bit isn’t worth the extra cost because on aluminum, its performance level is about the same as that of high speed steel. Skip the coatings on these drills —there’s no need to increase the already high cost. Especially avoid any coating with “Al” in the ingredients (AlTiN, TiAlN, etc.). A drill bit with a  bright finish is ideal.

When drilling hardened or stainless steel, select a drill point of at least 135° or higher. This spreads the workload out over a larger cutting surface. Since hardened steel and stainless steel are both quite difficult to drill into, using a drill press or a milling machine should provide the best results.

A good quality High Speed Steel (HSS) drill bit is suitable for use on mild steels, but if you need to get a lot of use from them, go with M35 cobalt drills, or even the aforementioned M42 cobalt drills.

This alloy is slightly stronger than 7050 aluminum and has very good fatigue resistance, making it ideal for applications that undergo cyclic loading. Its main alloying element is zinc and its typical applications include meter shafts and gears, aircraft fittings, and shaft keys.

Try to avoid the cheapest drill bits, or you could likely end up spending more in the long run. Always use cutting oil or coolant for any drilling operation.

Stainless steel can actually ‘work harden’ as it heats up—so keep your cool, take your time, and make sure the tool and work area stay well lubricated.

This aluminum alloy uses magnesium as its primary alloying element. It is very corrosion-resistant due to the lack of copper in its composition but it cannot be heat-treated. Aluminum 5052 is typically used in fuel tanks, sheet metal parts, and fuel/oil lines.

Design for manufacturing: The first way to save cost when machining an aluminum alloy part is by following design for manufacturing principles to limit the use of difficult-to-machine features. Learn more here.

Xometry offers a wide range of surface finishes suitable for aluminum alloys. The most popular surface finishing process is anodization. Both normal- and hard-coating anodizing are offered to improve the wear resistance and the corrosion resistance of the various available alloys. Chemical conversion coating and metal plating are also available for aluminum alloys. Learn more about the surface finishes we offer.

This aluminum alloy is one of the strongest available. Its main alloying element is zinc. Aluminum 7050 achieves its strength by sacrificing corrosion resistance; the inclusion of copper is the reason behind both effects. This alloy is also highly machinable. Its strength makes it ideally suited for aircraft structures.

This grade of aluminum is considered a general-purpose alloy. It has excellent machinability characteristics and can be easily welded. The primary alloying elements are magnesium and silicon. This aluminum alloy is regularly used to make electrical fittings, brake pistons, and bike frames.

There is only a slight difference between the alloying elements in aluminum 6063 as compared to 6061. This aluminum alloy is not as strong but offers better formability. As a result, it’s well-suited for pipes, railings, and extrusions.

This aluminum alloy resists fatigue well and is quite machinable, but exhibits poor weldability characteristics. It is not very resistant to corrosion, so it requires surface treatments if used in harsh environments. Aluminum 2024-T3 is typically used for bolts, aircraft fittings, and pistons.

Choose the right alloy: Not all aluminum alloys are equal in price. If the part is only a prototype, using the most advanced and expensive alloy may not be necessary. To learn more, contact a Xometry expert.

Aluminum is a lightweight metal with an excellent strength-to-weight ratio, making it ideal for applications in which metallic-level strength is required, but mass is still a concern. There are various alloys for aluminum, each denoted by the first number in their classification. The number indicates the main alloying element(s).
