Like other nickel/iron compositions, Invar is a solid solution; that is, it is a single-phase alloy.In one commercial grade called Invar 36 it consists of approximately 36% nickel and 64% iron, [4] has a melting point of 1427C, a density of 8.05 g/cm3 and a resistivity of 8.2 x 10-5 Ω·cm. [5] The invar range was described by Westinghouse scientists in 1961 as "30–45 atom per cent nickel".
An iron–nickel alloy or nickel–iron alloy, abbreviated FeNi or NiFe, is a group of alloys consisting primarily of the elements nickel (Ni) and iron (Fe). It is the main constituent of the "iron" planetary cores and iron meteorites .
Tungsten, usually alloyed with nickel, iron, or cobalt to form heavy alloys, is used in kinetic energy penetrators as an alternative to depleted uranium, in applications where uranium's radioactivity is problematic even in depleted form, or where uranium's additional pyrophoric properties are not desired (for example, in ordinary small arms ...
Tungsten steel is any steel that has tungsten as its alloying element with characteristics derived mostly from the presence of this element (as opposed to any other element in the alloy). Common alloys have between 2% and 18% tungsten by weight along with small amounts of molybdenum and vanadium which together create an alloy with exceptional ...

Ferrotungsten is relatively expensive, with the prices around $31–44 per kilogram of contained tungsten. [4] During World War 2, over 21,000,000 lb of Ferro-tungsten and other ferroalloys were shipped to Russia on lend-lease. [3] The cost was more than $12,000,000. Ferrotungsten comes from rich ore raw materials primarily of wolframite or ...
Alloy 230 is a nickel alloy, made up of mostly nickel and chromium, with smaller amounts of tungsten and molybdenum.This combination of metals results in a number of desirable properties including excellent strength, oxidation resistance at temperatures of up to 2,100 °F (1,150 °C) and nitriding-resistance.
Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress. They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength. Material properties are most often characterized by a set of numerical parameters called moduli.
