Nickel alloyproperties

Alloy 718 (AMS 5663) is bar that is already aged (precipitation hardened). As supplied, this material provides high tensile strength and hardness compared to 718 in the annealed condition.

Invar 36 is a nickel-iron, low-expansion alloy containing 36% nickel. It maintains nearly constant dimensions over the range of normal atmospheric temperatures, and has a low coefficient of expansion from cryogenic temperatures to about 500°F. The alloy also retains good strength and toughness at cryogenic temperatures. Invar 36 can be hot and cold formed and machined using processes similar to austenitic stainless steels.

End milling is not massively dissimilar to face milling when it comes to preparation; you still have to set the machine up correctly and position the material securely and exactly where you need to start cutting. This process is used by Xometry customers who need both axial and perpendicular cutting capabilities for things like profiles, slotting, plunge cutting, contouring, counterboring, and making keyways. Compared to face milling, the quality finish of end milling isn’t the best (0.29–0.95µm), but it still looks relatively good.

Inconel® 718 is a high-strength nickel base superalloy used for cryogenic temperatures up to long term service at 1200°F. The alloy is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition.

So we’ve established that both methods remove metal from a workpiece, but face milling is better for flat surfaces with stellar quality, while end milling has a lot more tricks up its sleeve and can do lots of different cutting tasks. As briefly covered in the intro, end milling can carry out face milling projects, but face milling can’t be used for end milling tasks because of the way the tools are designed. Basically, face milling is great at one thing, whereas end milling is good enough at many things.Â

Face milling is used to create high-quality flat surfaces with either a fly cutter, end mill, or shell mill. These cutting tools typically have different head inserts so you can swap them out as necessary, kind of like you would with a regular drill/driver. The material you want to cut should be placed face-up on the machine, perpendicular to the cutter’s axis. After you’ve adjusted all the important settings, like the spindle speed and feed rate, secure the material in place so that you can start cutting. The below diagram depicts the face-milling process.

A nickel base superalloy with excellent carburization, oxidation, and hot corrosion resistance. It has high creep rupture strength with exceptional ability to withstand repeated thermal shock.

Nickel-chromium alloy with tungsten and molybdenum additions. It boasts excellent oxidation resistance to 2100°F and superior strength at temperature.

The process you choose will really depend on your exact needs, and where factors like budget, finish, or capabilities sit on your list of priorities. To help you decide, we’ve put all the pros and cons of each of them in the table below.

Did you know that end milling can perform face milling tasks, but face milling tools can’t carry out end milling jobs? Although these two metal-removing milling processes are alike in many ways, they have some important differences that you have to know about before starting a project using any one of these methods. All is revealed below.

Some of our customers manage to make their cuts using this process in a single pass, but don’t worry if you need more than one (it happens to the best of us). Face milling does a great job of removing a lot of material quickly, but the surface quality finish is medium. You can face mill lots of metals like steel, aluminum, nickel, brass, and titanium, and use this method for leveling surfaces and raised edges, and making parallel surfaces, pockets, and recesses, too. Tools that are used for face milling are large diameter ones — including square-end tipped, ball nose, radius tipped, and chamfer tipped — and they could have many different inserts.

Incoloy® 800 is an austenitic heat resistant alloy designed for high temperature structural applications. The strength of it is achieved by controlled levels of carbon, aluminum and titanium along with a 2100°F minimum anneal to achieve a grain size of ASTM 5 or coarser.

RA 602 CA® alloy is the most oxidation resistant/high strength nickel alloy available. It is capable of extreme temperature use up to and beyond 2200°F (1200°C).

Inconel® 625 is a nickel-base alloy used both for its high strength and outstanding aqueous corrosion resistance. The strength of alloy 625 is primarily a solid solution effect from molybdenum and columbium.

Alloy 20 was designed specifically to withstand sulfuric acid. Its nickel, chromium, molybdenum and copper levels all provide excellent general corrosion resistance.

Alloy X is one of the most widely used nickel base superalloys for gas turbine engine components. This solid solution strengthened grade has good strength and excellent oxidation resistance to 2000°F.

End milling is a little more versatile and is used to make pockets, slots, recesses, shoulders, profiles, and cavities by cutting parallel to the tool spindle. It removes material with a tool sporting cutting edges on both the flat part (the end face) and the sides (peripheral). An end mill’s design also allows it to do some extra things, like engrave, make die cavities, and cut various shapes and contours. The diagram below shows how end milling works.

Inconel® 601 is a nickel-chromium alloy, that is highly resistant to oxidation through 2200°F. 601 alloy develops a tightly adherent oxide scale which resists spalling even under severe thermal cycling.

Low carbon, high purity, nitrogen-bearing “super-austenitic” stainless alloy. The AL-6XN® alloy was designed to be a seawater resistant material and has since been demonstrated to be resistant to a broad range of very corrosive environments
