  • Learn more about our nickel based alloys manufacturing process technology

At JLC, we start with the purest available raw materials to achieve the required chemical composition. A correct chemical composition is necessary to give uniform and required properties to different alloys. The alloys are Melted, Hot-Rolled and processed to final sizes using state-of-the-art technology.

We, at JLC, believe in continuous improvement; all processes are monitored at each step using statistical process control tools to ensure the best quality of the final products. The process for making each alloy is set after a detailed exercise using concepts such as Failure Mode Effect Analysis (FEMA) and Design of Experiments (DOE)

Raw Material
  • Only virgin materials used in melting for all alloys.
  • Nickel is sourced  from reputable international suppliers.
  • All other metals sourced from high-quality suppliers.
  • Most of the metals used are pure/electrolytic grade to ensure highest purity levels.
Melting
  • Completely integrated manufacturing facility;  starting from the melting stage.
  • Melting   performed in  modern electric  furnaces.
  • Capacity to melt in different batch sizes- big and small.
  • Special techniques to control  impurities and inclusions.
  • Unique processing technique ensures consistency and high surface quality.
Hot Rolling
  • Ingots pre-heated (red hot) and then hot-rolled on a high-speed rolling mill.
  • Ingots hot rolled to rods or strip form.
  • Assignment of roll-passes for different alloys.
  • Rolling carried out at high speeds to prevent high temperature oxidation of materials.
Wire Drawing
  • Heavy gauge wire drawn to size on modern high-speed drawing blocks.
  • Wet drawing for wire sizes below 2 mm.
  • Over 60 different types of wet wire drawing machines available based upon wire diameter and alloy.
  •  Diamond dies used to obtain bright and smooth surface quality.
  • Super fine wires up to diameters 0.05 mm also produced for special applications.
Annealing
  • In-house batch annealing and continuous annealing furnaces
  • Hot-rolled material subjected to batch annealing in controlled atmosphere furnaces.
  • Annealed material thoroughly cleaned and coated with a suitable lubricant.
  • Continuous annealing for intermediate and fine size wire for desired surface finish.
  • JLC has over 15 continuous annealing furnaces designed to anneal various Ni alloys.
  • All furnaces have inert atmosphere to give bright annealed wires.
Testing & Packing
  • All alloys produced undergo several stages of quality control for strict adherence to specifications.
  • In-house, well-equipped physical and chemical testing lab supports the production.
  • Well-equipped packaging department to ensure that all material is shipped defect-free and safely packaged.
  • Treated and IPPC marked wooden boxes.
  • Standard spools used as per DIN standards. Drum/pail packing is also available.
  • Thicker wires supplied in coils on pellets.
  • Specialized packaging in other forms provided as per the customer requirement.
