Stranded Wire

Vladimir Plant of Precision Alloys produces NiCr and Nickel stranded wire with excellent form stability and continuous operating characteristics for wide range of industrial applications. Standard wire supply in 19-strands and used at elevated temperatures in oxidized atmospheres.

Stranded wire is a main assembly in heating lateral and transverse pad heaters, carry out for heat-treating of complex shape tools and equipment outside the furnace (heat-exchangers, boilers, rollers, piping systems etc.)

Heating mats can be used at temperatures up to 1200°C.
Annealing temperature of parts can reach 1050°C.

  • The stranded wire can be manufactured in further specifictaion types : co-directional and oppositely-directed lay rope scheme
  • Different versions of the wire length (standard is 500 m).
  • The stranded wire can be: soft and hard.
  • Supplied on spools DIN 355, DIN 250, DIN 200.
