Design and FEM simulation<\/h2>\n

Every coil starts from a FEM (Finite Element Method) simulation<\/strong> process, which analyses the magnetic field distribution and heating depth in advance.<\/p>\n

This approach optimises the winding geometry, improves flux concentration, reduces Joule losses and ensures uniform, controlled heating.<\/p>\n

Simulation allows the coil to be customised for the material, operating frequency and workpiece shape, avoiding costly physical testing.<\/p>\n

\n

Construction material \u2013 Cu+Ag 0.1%<\/h2>\n

Aselt coils are made of Cu+Ag 0.1%<\/strong>, a material combining high electrical conductivity with mechanical strength even at high temperatures.<\/p>\n

Key characteristics include electrical conductivity above 100% IACS, mechanical strength up to 200 \u00b0C, low thermal deformation and a service life up to 20 times longer than pure copper.<\/p>\n

This material allows more efficient energy transfer<\/strong> and less wear in continuous duty cycles.<\/p>\n

\n

Fluxtrol\u00ae magnetic flux concentrators<\/h2>\n

To increase the efficiency of our coils we use Fluxtrol\u00ae<\/strong> magnetic materials as flux concentrators, directing the energy exactly where it is needed.<\/p>\n

Benefits include higher magnetic field intensity at the working point, lower lateral losses, faster and more uniform heating, and reduced energy consumption.<\/p>\n

The concentrators are shaped and integrated inside the coil to maximise magnetic performance and improve heat treatment quality.<\/p>\n

\n

Construction and welding<\/h2>\n

Every coil is crafted by hand and brazed with a high-conductivity silver alloy<\/strong> to ensure solid, impurity-free mechanical joints. The windings are shaped according to the FEM specifications.<\/p>\n

The main production phases include 3D design and FEM verification, bending and brazing, finishing and application of the Fluxtrol\u00ae concentrators.<\/p>\n

\n

Coil regeneration and maintenance<\/h2>\n

Aselt offers a complete coil regeneration<\/strong> service, extending the service life of the component and maintaining performance over time.<\/p>\n

Regeneration includes internal cleaning and pickling, replacement of the magnetic concentrators, renewal of brazed joints and insulating coatings, plus comparative electrical and magnetic testing.<\/p>\n

This service reduces operating costs<\/strong> and ensures production continuity, avoiding unexpected downtime.<\/p>\n","protected":false},"featured_media":3011,"template":"","meta":{"_acf_changed":false,"_yoast_wpseo_title":"Induction Heating Coils in Cu+Ag 0.1% Copper -
