Nickel Alloys
Kovar/Invar/Inconel & Other Nickel alloys
High-performance nickel alloys provide the high strength and structural toughness that make them optimal for a wide selection of industry uses and applications.
In order to improve their mechanical qualities and resistance to heat and corrosion, nickel alloys are a class of metals that mix nickel with other elements. Due to their remarkable strength and resilience, these alloys are well-suited for demanding uses in sectors like chemical processing, power generation, and aerospace. Nickel alloys are perfect for use in gas turbines, jet engines and chemical plants because they can tolerate high temperatures and corrosive conditions.
- Kovar is a nickel-iron-cobalt alloy known for its excellent thermal expansion characteristics.
- Invar is a nickel-iron alloy that exhibits superior dimensional stability across extreme temperatures.
- Inconel is a family of nickel-chromium "superalloys," all of which provide outstanding oxidation/corrosion resistance in high heat and high-pressure applications.
- Super Invar 32-5 Super Invar 32-5 is a magnetic, austenitic solid solution alloy composed of iron, nickel, and cobalt, engineered to minimise thermal expansion at ambient temperatures. At service temperatures of at least -67°F, this alloy stays austenite stable, and its thermal expansion is lower than that of the Invar 36 alloy (36% nickel-iron) in the -55°C to 95°C temperature range.
- Inconel 625 (Alloy 625) A nickel-based superalloy with exceptional strength and endurance to high temperatures is Inconel Alloy 625 (UNS designation N06625). Additionally, it exhibits exceptional resistance to oxidation and corrosion. Its resilience to extremes of temperature and stress, both in and out of water.
- Inconel 718 / NICKEL 600/NICKEL 625/NICKEL X-750/WASPALOY
- Monel is a group of alloys of nickel (from 52 to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon.
Titanium alloys
Titanium
Titanium metal is plentiful in the earth's crust and is economically produced from the ore minerals rutile (titanium dioxide) and ilmenite (iron-titanium oxide). Titanium's qualities include high strength, stiffness, toughness, low density, and exceptional corrosion resistance. These qualities are possible by a wide range of titanium alloys used in applications ranging from extremely low to high temperatures. This allows for weight savings in a variety of critical aircraft applications, as well as high-performance applications in the medical, chemical, and automotive industries.
Furthermore, titanium and titanium alloys produce durable protective surface layers, providing high corrosion resistance in a variety of conditions, including oxidising acids and chlorides, as well as exceptional raised temperature qualities up to approximately 550 C (1022 F) in some situations.
Titanium and titanium alloys can be divided into four classes depending on on their constituent phases:
1. Unalloyed or commercially pure titanium;
2. Alpha and near alpha alloys.
3. Alpha-plus-beta alloys.
4. Beta-alloys
Molybdenum
Molybdenum
- Molybdenum, or Mo, is an element in the periodic table with the number 42. Carl Wilhelm Scheele found it in 1778.
- Its name is derived from the Greek word molybdos, meaning lead.
It is a silvery-white, strong transition metal with one of the highest melting points among all pure elements. - Acids can gradually damage it.
- Molybdenum is reported to have 35 isotopes with atomic masses ranging from 83 to 117.
Applications:
TWT and other electronic applications
Rhenium
Rhenium
- Rhenium (CAS: 7440-15-5) is a rare, silver-white metal known for its high melting point and high density. Its atomic number is 75, and it is one of the heaviest elements. Rhenium is obtained as a by-product of molybdenum refinement and is used in superalloys for jet engine components due to its excellent high-temperature properties.
Applications:
TWT and vacuum electronic applications

Tungsten
Tungsten
- Tungsten has the highest melting point of all metals as well as a remarkably high modulus of elasticity. Thanks to its outstanding thermal properties, tungsten can easily withstand even the highest temperatures. Tungsten also stands out for its relatively high density and is therefore used in a wide range of industrial applications such as in the aviation and aerospace industries, the electrical engineering sector, and in electronics.
OFHC copper
OFHC copper
- Oxygen-free copper (OFC), also known as oxygen-free high thermal conductivity (OFHC), is a class of wrought high-conductivity copper alloys that have been electrolytically processed to reduce the oxygen content to 0.001% or less. Oxygen-free copper is a high-quality copper with nearly no oxygen content. Copper's oxygen level influences its electrical characteristics and can impair conductivity.
