  • 45/55 Ni Cu Resistance Wire (For Springs)

    A Nickel-Copper alloy wire used mainly for its medium range electrical resistivity and very low temperature-coefficient of resistance. 45/55 Ni Cu Resistance Wire is also known as Constantan, Hecnum, Eureka, Ferry, and Advance.


  • 80/20 Ni Cr Resistance Wire (For Springs)

    An alloy wire used at operating temperatures up to 1200°C (2200°F). Its chemical composition gives good oxidation resistance especially under conditions of frequent switching or wide temperature fluctuations. 80/20 Ni Cr Resistance Wire is also known as Nichrome / Nicrove V, Brightray C, Cronix 80, Nicrothal 80, Chromalloy, Chromel, and Gilphy 80.


  • Nickel 200 (For Springs)

    Nickel 200 is commercially pure and has good mechanical properties and excellent corrosion resistance to alkalis i.e. Sodium hydroxide. It also has good electrical, thermal and magneto-strictive properties. Nickel 200 is also known as Phyweld 200.


  • Nickel 201 (For Springs)

    A commercially pure Nickel (typically 99.6% Nickel), Nickel 201 is essentially the same as Nickel 200, but with a lower Carbon content to prevent embrittlement by inter granular carbon at temperatures over 315°C (600°F). Lower carbon content also reduces hardness. Nickel® 201 is also known as Phyweld 201.


  • Nickel 270 (For Springs)

    A high purity grade of nickel that is made by powder metallurgy. Nickel 270 is also known as HPM 270 Nickel.


  • Nilo 36 (For Springs)

    A Nickel-Iron, low expansion alloy containing 36% Nickel. It maintains near constant dimensions over the range of normal atmospheric temperatures and has a low coefficient of expansion from cryogenic temperatures to about 500°C (930°F). Nilo 36 also retains good strength and toughness at cryogenic temperatures. Nilo 36 is also known as Invar / Invar 36, Supra 36, and Pernifer 36.


  • Nilo 42 (For Springs)

    A Nickel-Iron, low expansion alloy containing 42% Nickel. It has a low and nominally constant coefficient of thermal expansion from room temperature to about 300°C (570°F). Nilo 42 is also known as Invar 42, Pernifer 40, Dilaton 42, and Glass Sealing 42.


  • Nilo 48 (For Springs)

    A Nickel-Iron, controlled expansion alloy containing 48% Nickel. Its coefficient of thermal expansion was designed to match that of soft lead and soda-lime glasses. This alloy also has a high inflection point. Nilo 48 is also known as Invar 48 and Magnifer 50.


  • Nilo 52 (For Springs)

    Nilo 52 was designed for use with a variety of soft glasses. It is known for its almost constant coefficient of thermal expansion up to approx. 565°C (1050°F). Nilo 52 is also known as Invar 52, Pernifer 50, and Glass Sealing 52.


  • Nilo K (For Springs)

    A Nickel-Iron-Cobalt, controlled expansion alloy containing 29% Nickel. Its coefficient of expansion (which decreases with rising temperature to the inflection point), matches the expansion rate of borosilicate glasses and alumina ceramics. Nilo K is also known as Kovar, Dilver, and Pernifer 2918.


  • Stainless Steel 1.4310 (For Springs)

    Stainless Steel 1.4310 is capable of high tensile strength following cold work. It can be used for any TSMC spring product such as wave springs, retaining rings and compression springs.
