Tech Steel & Materials offers nickel and cobalt alloys in a variety of shapes and parts – rod, bar, wire, sheet, plate, strip, tube, pipe, castings and forgings – for use in the aerospace, military, marine and power plant industries.
Selected for their great strength and wear-resistant properties at high temperatures, these alloys have increasingly replaced steel in aircraft jet engines.
Properties
Nickel and cobalt alloys have high strength and creep resistance and are resistant to softening and metals loss at high temperatures from oxidation, sulfidation or carburization.
Nickel- and cobalt-based alloys can be separated into three categories: high temperature, corrosion resistance and electrical conductivity.
High-temperature alloys offer unique strength and/or corrosion-resistant properties at elevated temperatures. Their nickel content ranges from 25% to 60%, with measurable amounts of chromium, molybdenum, columbium and titanium. High-temperature, heat-resistant alloys of nickel and cobalt are often used where high surface stability, particularly creep resistance, is required. The most popular use for the high-temperature cobalt alloy is in gas turbine (turbojet) aircraft engines.
Corrosion-resistant nickel and cobalt alloys resist corrosion due to nickel’s slow rate of oxidation at room temperature and cobalt’s protective shell created by an oxide film. These alloys are routinely used in chemical processing, heat treating, pollution and waste control applications. Nickel and cobalt alloys that conduct electricity are ideal for electronics and situations involving contact with electricity. This alloy category is often used in applications such as TV interiors and lightbulbs.
Applications
Common applications for nickel and cobalt alloys are: engine plumbing, pumps, valves, piping systems, processing equipment, turbines, assemblies, tools, chemical processing, oil and gas well piping.
