Common types of nickel-alloys include Inconel, Hastelloy, Waspaloy, stainless steels including 304, 316 and 17-4—and others. Given a sharp tool and the right cutting parameters, pure nickel is not terribly difficult to turn or mill, although nickel alloys such as Ni-Span-C 902 and Monel K-500 bear machinability ratings of 15 percent or less.
Details
Nickel alloys work harden rapidly, and the high pressures produced during machining cause a hardening effect that slows further machining and may also cause warping in small parts. Using cold-drawn stress-relieved material is preferable for machining. Hot-rolled is less desirable and annealed is least preferred for most applications.

Because nickel-based alloys are tough, stepovers should be well below the radius of the milling tool and feed rates relatively high. Conversely, the minimum depth of cut for turning should be no less than the tool nose radius, and preferably several times that if possible.

Traditional methods of machining for nickel-based superalloys. The most important characteristic of nickel-based superalloys compared to other materials is that these are much stronger at cutting temperatures. They are very sensitive to a higher temperature which is generated during traditional machining processes.

Nickel-based superalloys are widely used in the manufacturing of aero-engine turbine disks, compressor disk, and other essential parts. The processing mechanisms result in low machinability due to the combined properties of high-temperature hardness, mechanical strength, and wear resistance. Laser-assisted machining (LAM) is a hybrid method to …

Since nickel is composed in two types of ores, both of them are mined differently. The sulfide ores are mined using underground mining methods though open-pit mining can also be done in early stages. The laterite ores are mined through applying earth-moving operation techniques.

Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice …

Short electric arc milling (SEAM) is an electrical discharge machining method characterized by low voltage and high current. This method has high machining efficiency, and the eroded material is quickly discharged from the discharge gap by a high-speed rotating tool electrode and a certain pressure of the gas-liquid mixed medium. In this paper, the effects of tool polarity, …

The invention relates to nickel-phosphorus alloys, in particular to a preparation method for the nickel-phosphorus alloys. The method includes that a reaction ball milling method is utilized to perform ball milling on nickel powder and red phosphorus at room temperature so as to prepare massive nickel-phosphorus alloys. An alloy phase is composed of Ni and Ni3P.
