The remaining 40% is generally used to make various alloys and specialty steels, electrodes, filaments, wires, as well as diverse components for electric, electronic, heating, lighting, and welding applications.

Invar is an alloy of nickel and iron. This alloy is also known generically as FeNi36 (64FeNi in the US). Invar is notable for its uniquely low coefficient of thermal expansion.

Invar was formerly used for absolute standards of length measurement and is now used for surveying tapes and in watches and various other temperature-sensitive devices. Invar is used where high dimensional stability is required, such as precision instruments, clocks, seismic creep gauges, television shadow-mask frames, valves in engines and large aerostructure molds.

Constantan is a copper–nickel alloy consisting usually of 55% copper and 45% nickel and specific minor amounts of additional elements to achieve precise (almost constant) values for the temperature coefficient of resistivity. That means, its main feature is the low thermal variation of its resistivity, which is constant over a wide range of temperatures. Other alloys with similarly low temperature coefficients are known, such as manganin.

Constantan is used for the measurement of temperature, the formation of thermocouple or resistance purpose.

Nickel silver, known also as German silver, nickel brass or alpacca, is a copper alloy with nickel and often zinc. UNS C75700 nickel silver 65-12 copper alloy has good corrosion and tarnish-resistance, and high formability. Nickel silver is named due to its silvery appearance, but it contains no elemental silver unless plated.

Nickel silver alloys are used for decorative applications, jewellery, model making, musical instruments (e.g., flutes, clarinets), flutes ball point refills, screws, rivets and fishing rods, test probes.

Galinstan is a eutectic alloy composed of gallium, indium, and tin (hence its name, which is derived from the gallium, indium, and stannum, the Latin name for tin).

Due to the low toxicity and low reactivity of its component metals, in many applications, galinstan has replaced the toxic liquid mercury or the reactive NaK (sodium–potassium alloy). Metals or alloys like galinstan that are liquids at room temperature are often used by overclockers and enthusiasts as a thermal interface for computer hardware cooling.

Wood is an organic material – a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. It is common to classify wood as either softwood or hardwood. The wood from conifers (e.g. pine) is called softwood, and the wood from dicotyledons (usually broad-leaved trees, e.g. oak) is called hardwood.

Pines are among the most commercially important tree species valued for their timber and wood pulp throughout the world. Some species have large seeds, called pine nuts, that are harvested and sold for cooking and baking.

Gasoline, or petrol is a clear petroleum-derived flammable liquid. Currently, the main source of fuel for road vehicles is petroleum oil.

Gasoline is used primarily as a fuel in most spark-ignited internal combustion engines. The usage and pricing of gasoline (or petrol) results from factors such as crude oil prices, processing and distribution costs, local demand, the strength of local currencies, local taxation, and the availability of local sources of gasoline (supply). Since fuels are traded worldwide, the trade prices are similar.

In general, diesel fuel is any liquid fuel specifically designed for use in diesel engines, whose fuel ignition takes place, without any spark, as a result of compression of the inlet air mixture and then injection of fuel. Currently, the main source of fuel for road vehicles is petroleum oil.

Acetylene is a colorless, highly flammable gas with an ethereal odor. Acetylene is a hydrocarbon and the simplest alkyne with the formula C2H2. Commercial acetylene will have a garlic-like odor. It is shipped with dissolved acetone in its gaseous form.

Typical uses oxyacetylene chemical synthesis and especially for welding and cutting. Among all other gases, acetylene is capable of producing the hottest flame. The welding process that uses acetylene is known as oxy-fuel cutting or gas cutting.
