Constantan® is a copper-nickel alloy that contains specific minor amounts of additional elements to achieve precise values for the temperature coefficient of resistivity. Careful control of melting and conversion practices results in a very low level of pinholes at ultra-thin thicknesses. The alloy is used extensively for foil resistors and strain gauges. The TCR can be adjusted from the furnished cold rolled values by using a low temperature heat treatment to achieve compensation for all types of spring elements. The foil is normally supplied with 90% cold reduction and a smooth bright surface. The foil is reasonably flat at 4” wide and nearly free of pinholes. The cold rolled foil can be produced with a TCR between +10 to –35 PPM/°C. The heat treatment will shift the foil TCR to the desired value. A typical heat-treat curve for Constantan® shows decreasing resistivity but increasing TCR with increased heat-treating temperature.

Beryllium Copper 25 is a Copper base alloy with the capability of being strengthened by precipitation heat treatment. The alloy furnishes the best combination of electrical conductivity, corrosion resistance and mechanical strength necessary for numerous electronic and electromechanical devices.

Beryllium Copper 25 is able to be soldered, brazed, and welded by most standard techniques. The brazing temperature must be kept under 1450º F and cycle time minimized to avoid loss of heat treated strength. Heat treating should be performed subsequent to welding to obtain uniform high strength. The alloy is not susceptible to an increase in magnetic attraction from plastic deformation during service

Alloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H/HT and the addition of up to 1.20 percent aluminium and titanium in alloy 800HT. Alloy 800 was the first of these alloys and it was slightly modified into Alloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. In heat treatment applications Alloy 800HT has further modifications to the combined titanium and aluminium levels (.85-1.20%) to ensure optimum high temperature properties. Alloy 800H/HT was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both carborisation and to embrittlement from precipitation of sigma phase. Please note that we have a minimum order value of £10,000.

The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition. Alloy 276 is widely used in the most severe environments such as mixed acid chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour oil and gas. Please note that we have a minimum order value of £10,000.

Nickel based alloys are very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications. Nickel alloy tubes offer excellent corrosion resistance, high melting points and resistance to oxidationIn addition to their high melting points and resistance to oxidation and corrosion, nickel alloys are very ductile. Nickel based alloys have a higher ability to accept alloying elements in solid solution than other stainless steel or iron-based alloys. They cantherefore maintain higher metallurgical stability. The combination of high alloying with multiple elements can provide very good corrosion resistance in a wide range of environments while still maintaining good welding and forming characteristics. Please note that we have a minimum order value of £10,000.

Alloy 600 is a nickel-chromium alloy designed for use from cryogenic to elevated temperatures in the range of 2000°F (1093°C). The high nickel content of the alloy enables it to retain considerable resistance under reducing conditions and makes it resistant to corrosion by a number of organic and inorganic compounds. The nickel content gives it excellent resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance to alkaline solutions. Its chromium content gives the alloy resistance to sulphur compounds and various oxidizing environments. In strong oxidizing solutions like hot, concentrated nitric acid Alloy 600 has poor resistance. Alloy 600 is relatively un-attacked by the majority of neutral and alkaline salt solutions and is used in some caustic environments. The alloy resists steam and mixtures of steam, air and carbon dioxide. Please note that we have a minimum order value of £10,000.

Alloy 625 is a nickel-chromium-molybdenum alloy used for its high strength, excellent fabricability and outstanding corrosion resistance. Service temperatures can range from cryogenic to 980°C (1800°F). Alloy 625 strength is derived from the solid solution strengthening effect of molybdenum and niobium on its nickel-chromium matrix. Thus precipitation-hardening treatments are not required. This combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization. Please note that we have a minimum order value of £10,000.
