The 5 Most Popular Types of Nickel Alloy Round Bar

Materials made with nickel and a few other elements are nickel-based alloys. The corrosion resistance and strength of nickel-based alloys are well-known. As a metallic element, nickel can be used to combine with other metals to modify their properties. Nickel adds corrosion resistance and strength to stainless steel, making them ideal for use in chemical facilities that may contain caustic compounds. Added to nickel-based alloys are chemical constituents such as chrome, cobalt, molybdenum, iron, and tungsten.

Each of these nickel alloy round bar types is discussed in detail below:

Round bars made of nickel-iron alloys:

A nickel-iron alloy can be used in applications where a low coefficient of expansion is desirable. Invar 36, also known as Nilo 6 or Pernifer 6, has a coefficient of thermal expansion about a tenth that of carbon steel. A major advantage of nickel-iron alloys is their high degree of dimensional stability, which is very useful in measuring instruments and thermostat rods.

Nickel copper round bars:

Nickel-copper alloys are resistant to corrosion by salt water and seawater, which makes them ideal for marine applications. These alloys are commonly used for marine pipe systems, pump shafts, and seawater valves. Alloys made from nickel copper have a minimum nickel content of 63 percent and a copper content of 28-34 percent.

Alloys containing nickel and molybdenum round bars:

Nickel-molybdenum alloys are resistant to a variety of acids and reducers, including hydrochloric acid, hydrogen chloride, sulfuric acid, and phosphoric acid. This type of alloy, such as Alloy B-2, has a molybdenum concentration of 29-30% and a nickel concentration of 66-74 percent in its chemical makeup.

Bars of Nickel and Titanium alloy:

Shape memory and shape preservation are features of nickel-titanium alloys. The alloy will remember its original shape by being shaped at a high temperature and then deformed at a low temperature in the same manner, when it is heated to this so-called transition temperature.

Round bars of Nickel, Chromium, and Molybdenum:

These Nickel Alloy Round Bars perform well when exposed to reducing acids such as hydrochloric or sulfuric acids, as do nickel-molybdenum alloys. In addition to heat transfer, evaporator coils, and reaction vessels, this alloy is used in pollution control components, such as stack liners, ducts, and scrubbers. Alloys made from this metal are primarily nickel-based, with minor amounts of molybdenum, chromium, iron, and tungsten as well as other metals like manganese.
