    NAS 36LG: Click on product image for additional information & specs

    At 36 percent, the primary component of NAS 36LG is nickel, giving this alloy an extremely low coefficient of thermal expansion—about one-tenth that of 18-8 stainless steel.  NAS 36LG maintains thermal stress due to temperature variation at an extremely low level.  When used with low-temperature materials, complex surface forms such as waves, bellows and loop patterns are not required, making NAS 36LG an easy metal to work with.  This alloy has a high ductility at extremely low temperatures and is particularly good for welding.  Given these properties, NAS 36LG is used in liquefied natural gas ships, membrane material for land container tanks, and a variety of container and piping materials for handling extremely low-temperature fluids.

  • Titanium












    Various grades or titanium plate, bar, and sheet are manufactured domestically.  Titanium has a high strength, low weight ratio and outstanding corrosion resistance inherent to titanium.  Titanium is an alloy with a wide and diversified range of successful applications which demand high levels of reliable performance in a wide variety of industries including aerospace, chemical plant, power generation, oil and gas extraction, sports, and other major industries.

    Titanium has become an increasingly popular choice for engineering applications, replacing heavier, less serviceable or less cost-effective materials while often exceed performance and service life expectations.  Ti6Al4V is the most widely used titanium alloy.  It features good machine ability and excellent mechanical properties.  Ti6Al4V offers the best all-round performance for a variety of weight reduction applications in aerospace/aircraft industries.

  • Steel





    Steel is an alloy of iron and carbon.  Carbon is the primary alloying element, and its content in the steel is between 0.002% and 2.1% by weight.  Additional elements may also present in steel such as phosphorus, sulfur, silicon, and traces of oxygen, nitrogen and aluminum.  Alloy steel is steel to which additional alloying elements have been intentionally added to modify the characteristics of steel include: manganese, nickel, chromium, molybdenum, boron, titanium, vanadium and niobium.  Modern steels are made with varying combinations of alloy metals to fulfill many purposes.  High strength low alloy steel has small additions (usually < 2% by weight) of other elements, typically 1.5% manganese, to provide additional strength for a modest price increase.  Low alloy steel is alloyed with other elements, usually molybdenum, manganese, chromium, or nickel, in amounts of up to 10% by weight to improve the harden ability of thick sections.  Some more modern steels include tool steels, which are alloyed with large amounts of tungsten and cobalt or other elements to maximize solution hardening.  This also allows the use of precipitation hardening and improves the alloy's temperature resistance.

  • Aluminum



















    Aluminum is a silvery white to dull gray, soft, durable, lightweight, malleable and ductile metal.  It is nonmagnetic and does not easily ignite.  Aluminum is the third most abundant element (after oxygen and silicon), and the most abundant metal, in the Earth's crust.  It makes up about 8% by weight of the Earth's solid surface.  Aluminum metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments.  Instead, it is found combined in over 270 different minerals.  Aluminum is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation.  Structural components made from aluminum and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials.  The most useful compounds of aluminum, at least on a weight basis, are the oxides and sulfates.  Aluminum is a good thermal and electrical conductor, having 59% the conductivity of copper, both thermal and electrical, while having only 30% of copper's density.  Aluminum is capable of being a superconductor, with a superconducting critical temperature of 1.2 Kelvin and a critical magnetic field of about 100 gauss.  Globally, Aluminum is the most widely used non-ferrous metal, used in every major industry.

  • Stainless Steel












    Stainless Steel

    Stainless steels and surgical stainless steels contain a minimum of 11% chromium, often combined with nickel, to resist corrosion, such as rust. Some stainless steels, such as the ferritic stainless steels are magnetic, while others, such as the austenitic, are nonmagnetic.  Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments.  There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure.  Stainless steel is used where both the properties of steel and resistance to corrosion are required.  Stainless steel differs from carbon steel by the amount of chromium present.  Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal's internal structure, and due to the similar size of the steel and oxide ions they bond very strongly and remain attached to the surface.  Stainless steel’s resistance to corrosion and staining, low maintenance and familiar luster make it an ideal material for many applications.  There are over 150 grades of stainless steel, of which fifteen are most commonly used.  The alloy is milled into coils, sheets, plates, bars, wire, and tubing to be used in the aerospace and other industries.
