Your choices are... | |||
Alloying - Master Alloy | A master alloy has all of the major alloying constituents in concentrated form. For example, a 10% addition of a 60% aluminum - 40% vanadium composition master alloy combined with 90% pure titanium will produce Ti-6Al-4V alloy, which is the workhorse titanium alloy for aerospace applications. | ||
Alloying - Elemental Addition | Elemental additions are pure metal constituents added into a melt such as manganese or chromium metal additions for steel. | ||
Alloying - Microalloying | Microalloying modifiers are additions added in small amounts that have a significant impact on properties or processing. Rare earth element (RE) additions in small amounts can dramatically alter surface energy and melt penetration in a weld pool, refinement of the grain structure, and inclusion morphology. Rare earth (RE) elements have been called the ``vitamins of metals". Microalloyed and high strength low alloy steel represent 12% of the steel produced worldwide. Microalloyed steel is defined as a steel (an iron-carbon alloy) containing small amounts of vanadium, niobium, and/or titanium with any elemental addition not exceeding 0.10% where the total microalloying elements typically do not exceed 0.15%. | ||
Austenitizer | An alloying addition that promotes the formation of an austenitic phase in iron, steel, nickel, or other systems. | ||
Deoxidation / Killing Agent | Deoxidizing or killing agents such as aluminum, silicon, or calcium are added into a steel or iron alloy melt to absorb melt resulting in the absence of gas release during the solidification process. A killed steel melt solidifies quietly in ingot or billet molds. The killing stops any additional reaction between the carbon and oxygen, preserving the carbon content desired. Rimmed, unkilled, capped, or semi-killed steels will have greater variation in composition across the cast ingot. | ||
Desulfurization / Sulfur Control | Desulfurizing agents reduce or control the morphology of sulfur in a steel or alloy. Sulfur tends to wet the grain boundaries, resulting in hot shortness or brittle condition steel or iron alloys during hot working processes. Manganese additions to steel or iron alloys form manganese sulfides, which are nodular in nature resulting in strengthening of the grain boundaries. | ||
Ferritizer | An alloying addition that promotes the formation of the ferrite phase in iron, steel, or other metal systems. | ||
Grain Refiner / Nucleant | Grain refiners, nucleants, or nucleating agents promote rapid crystallization and a finer crystal size by providing many points for crystals to start growing during solidification. | ||
Innoculant (Nodulizer / Spheroidizer) | Inoculants, nodulizers, or spheroidizers are added to cast irons to form spherical shaped graphite nodules resulting in ductile cast iron. Without nebulization, graphite flakes form resulting in a more brittle cast iron. Small amounts of magnesium and cerium alloying additions or inoculants are used to form ductile cast iron. | ||
Modifier - Corrosion / Oxidation | Alloying addition added to enhance corrosion resistance such as chromium additions to iron, nickel, copper or cobalt based alloys | ||
Modifier - Castability / Fluidity | Castability and fluidity modifiers allow a molten metal to better flow into and fill a mold during casting processes. | ||
Modifier - Machinability / Chip Former | Sulfur, lead, tellurium, selenium, bismuth, and phosphorous are additives used in steel, copper, or aluminum alloys to enhance chip brittleness and enhance machinability. | ||
Modifier - Toughener / Ductility | Additives or modifiers that increase ductility or toughness of the alloy or metal by nodularizing brittle phases, altering the grain structure or microstructure, or other phase transformation to promote a more ductile crystal structure or condition. | ||
Modifier - Stabilizer | Stabilizers or stabilizing agents promote the stability of a particular phase or reduce dissolution. For instance, niobium, titanium, and tantalum are carbide stabilizers in steel. Titanium carbides, tantalum carbides, and niobium carbides are thermodynamically vary stable and difficult to dissolve in a steel melt during welding. Without stabilizers, chromium carbides may form at the grain boundaries reducing the chromium content below 12%, which increase the chance for inter-grannular corrosion to occur. The carbon combines preferentially with the carbide stabilizers, reducing or eliminating the depletion of chromium at the grain boundaries. | ||
Modifier - Strengthening / Hardening | Strengthening alloying additives increase alloy strength or hardness by various mechanism such as straining the lattice in solid solution or interstitial solution formation, promoting the formation of second phases, precipitation hardening, phase transformations, hardening reaction, and martensite formation. | ||
Modifier - Weldability / Joining | Alloying additions used to enhance weldability, joining, (brazing, soldering) or joint quality by controlling stages such as wetting, penetration, solidification, liquation, and second phase formation in the heat affect zone (HAZ). | ||
Specialty / Other | Other unlisted, proprietary, specialized, or patented alloying addition. | ||

Steel alloys are used in a wide variety of applications in almost every industrial segment. Mild steels and low carbon steels can be fabricated easily by machining, forming, casting, and welding. | ||
Cast Iron | Cast iron is an iron alloy with high amounts of carbon. This category includes ductile iron, gray iron, and white cast iron grades. Differences in grades are due to variations in composition and processing. | ||
Cobalt / Cobalt Alloy | Cobalt and cobalt alloys are non-ferrous magnetic alloys with high strength and toughness, excellent corrosion and oxidation resistance, and high temperature strength. Cobalt can also be magnetized. Cobalt's properties result in the use of cobalt alloys in jet engine super-alloy components, prosthetic devices, magnets, and cutting tool binders. Cobalt is a useful alloying element in tool, maraging, and other alloy steels. | ||
Copper, Brass or Bronze Alloy | Copper and copper alloys are non-ferrous metals with excellent electrical and thermal conductivity as well as good corrosion resistance, ductility, and strength. Copper alloys are relatively easy to fabricate by forming, casting, or machining. Pure copper is more difficult to weld, cast, or machine. Brass, tin bronze, leaded brass, beryllium copper, and zirconium copper are examples of copper alloys. Copper is useful as an alloying element in aluminum alloys and powder metal based iron alloys. Copper is a versatile metal with applications in many industrial and commercial segments. Copper's high electrical conductivity (100% IACS) makes it extremely useful in electrical and electronic applications. | ||
Low Melting (Tin, Lead, Indium, etc.) | Lead, tin, and white metals are low melting non-ferrous metals and alloys. Lead and white metal alloys are used as solders, battery electrodes, bearing liners, decorative products, and coatings. They are also used in other specialized applications. Indium, tin, lead, and antimony are used to manufacture semiconductors. | ||

Refractory metals and alloys are metals with melting points above ~1750 C (~ 32000 F). Refractory metals are used in high temperature, structural, electrical, and other specialty applications. Reactive metals combine readily with oxygen at elevated temperatures to form very stable oxides. Titanium, zirconium, and beryllium are considered reactive metals. Finely divided reactive metals can react explosively with oxygen and are often added to rocket fuels or combustible mixtures. A highly stable oxide film formed on the alloy surface provides protection against further oxidization or corrosion at low to moderate temperatures. Reactive metals can become embrittled if there is too much interstitial absorption into the lattice of oxygen, hydrogen, and nitrogen. | ||
Stainless Steel | Stainless steels are highly corrosion resistant, ferrous alloys that contain chromium and/or nickel additions. There are three basic types of products: austenitic stainless steels, ferritic and martensitic stainless steels, and specialty stainless steels and iron superalloys. Austenitic stainless steels (AISI 300 / 200 Series) are highly corrosion resistant, ferrous alloys that contain chromium and nickel or manganese additions. Generally, austenitic stainless steels are more corrosion resistant than ferritic or martensitic stainless steels. Annealed austenitic stainless steels are non-magnetic. Cold working is used to harden austenitic stainless steels because these alloys do not respond to conventional quench and temper hardening processes. Ferritic and martensitic stainless steels are highly corrosion resistant, ferrous alloys that contain chromium and/or carbon additions. Ferritic stainless steels are soft, easy to form metal alloys. Cold working is used to harden ferritic stainless steels because these alloys do not respond to conventional quench and temper hardening processes. Ferritic stainless steels are formed to fabricate mufflers and other sheet metal components that require good corrosion resistance. Martensitic stainless steels can be hardened by a conventional quench and temper operation. Martensitic stainless steels are used for knife blades, tooling, or other applications that require good corrosion resistance combined with higher hardness and wear resistance. Specialty stainless steels and iron superalloys are highly corrosion resistant, ferrous alloys containing chromium, nickel, or other alloying additions to provide high strength or heat resistance. Duplex and precipitation hardening stainless steels belong in this category. | ||
Titanium / Titanium Alloy | Titanium and titanium alloys are non-ferrous metals with excellent corrosion resistance, good fatigue properties, and a high strength-to-weight ratio. Titanium's properties result in the use of titanium and titanium alloys in aircraft or airframe parts, jet engine super-alloy components, corrosion resistant chemical process equipment (valves, piping, and pumps), prostheses or medical devices, and marine equipment. | ||

Specific tool steel grades are available for die or cold work, hot work, high speed, and shock resistance applications. Tool steel alloys are used in a wide variety of applications that require wear resistance. They are difficult to fabricate in their hardened form and are usually EDM-machined or grounded to achieve the tolerances required for tooling applications. EDM is an acronym for electrical discharge machining; this is a process that can cut small or odd-shaped angles, intricate contours, and cavities in extremely hard steels and exotic metals. | ||
Tungsten / Tungsten Alloy | Tungsten is a refractory metal with a very high melting point and high density. Tungsten and tungsten alloys are used to fabricate light bulb filaments, PVD evaporation crucibles, EDM electrodes, electrical contacts, and in other high temperature components. The high density of tungsten alloys are put to use in penetrators and balancing weights. | ||
