Nichrome (NiCr) Fittings Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies Nichrome Fittings from ready stock in Mumbai to customers across India and in more than 40 export markets. Fittings carry the same corrosion duty as the pipe they join but see higher stress concentration at every change of direction, so grade traceability and wall thickness at the extrados matter more here than anywhere else in a piping system.
Nichrome covers nickel-chromium resistance alloys specified by ratio for electrical heating and precision resistors. Fittings are supplied with heat-number traceability and can be bevelled, tacked or pre-fabricated into spools on request.
Sizes and Specifications
| Size range | Butt-weld fittings 1/2" to 48" NB in Sch 5S to Sch XXS; forged socket-weld and threaded fittings 1/8" to 4" NB in 3000#, 6000# and 9000# classes. |
|---|---|
| Types and finishes | Elbows (45° and 90°, long and short radius), tees (equal and reducing), reducers (concentric and eccentric), caps, stub ends, couplings, unions, plugs and bushings. |
| Specifications | ASME B16.9 and B16.28 for butt-weld and ASME B16.11 for forged fittings set the dimensions. The material is certified to the nichrome grade's own standard, which the quotation and the 3.1 certificate state. |

Chemical Composition
Grades are named for their nickel and chromium ratio: 80/20 is 80% Ni with 20% Cr; the 60/15, 40/20 and 30/20 grades substitute iron for nickel, trading maximum service temperature for cost.
Mechanical and Physical Properties
Resistivity sits near 1.09 ohm-mm2/m for 80/20 with a very low temperature coefficient. Maximum element temperature is about 1200°C for 80/20, falling to roughly 1100°C for the iron-bearing grades.
Industry Applications
How fittings is used
Fittings are factory-made wrought components, dimensioned to ASME B16.9 for butt-weld and ASME B16.11 for socket-weld. They are the 45, 90 and 180 degree elbows, tees, reducers, caps and lap-joint stub ends that change direction, branch or change bore in a process line, and they are specified to match the pipe they join in both alloy and schedule so the weld and the corrosion behaviour stay continuous.
| Industry | Typical use |
|---|---|
| Industrial heating | Furnace elements, heating coils and radiant heaters. |
| Appliances | Toasters, hair dryers, ovens and immersion heaters. |
| Electronics | Precision resistors, thin-film resistive layers and thermocouples. |
| Automotive | Glow plugs, seat heaters and sensor elements. |
| Aerospace | De-icing elements and cabin heating systems. |
Testing and Certification
Every consignment ships with an EN 10204 3.1 mill test certificate stating heat number, chemical analysis and mechanical properties. Depending on grade and specification we can supply positive material identification (PMI), ultrasonic and dye-penetrant testing, intergranular corrosion testing to ASTM A262 or G28, hydrostatic testing, and third-party inspection release notes from Lloyd's Register, Bureau Veritas, SGS or TUV.
Aurico Alloys LLP operates an ISO 9001:2015 quality management system. Material for sour service can be supplied certified to NACE MR0175 / ISO 15156 where the grade permits.
