In our latest recorded video presentation, Fluxtrol’s Rob Goldstein, FASM, breaks down how Soft Magnetic Composite (SMC) impeder cores can dramatically improve high-frequency tube welding performance, resulting in lower energy consumption and decreased emissions at the same production speed. Ultimately this leads to increased throughput, uptime, and profitability.
Highlights From Rob’s Research
✔️ Over 30% reduction in welding current at the same line speed.
✔️ Remove unexpected downtime due to ferrite impeder lifespan—run production faster, longer.
✔️ Nearly 40% lower welding power with maintained weld quality.
✔️ Lower kWh per ton, cutting both operating costs and CO₂ emissions.
✔️ Higher power density in the weld V, enabling efficient heating with less input power.
Fluxtrol Supports New Student Research in Induction Heating
Rapid induction heating is opening new possibilities for more efficient, sustainable processing of advanced high-strength steels, and Fluxtrol is proud to support the next generation of researchers driving this work. This summer, Fluxtrol hosted Alec Williamson, PHD Candidate in the ASPPRC of the Colorado School of Mines, in an internship role as a research engineer. In collaboration with Rob Goldstein, Alec spearheaded research in rapid induction heating as a viable alternative to conventional gas-fired furnaces in AHSS continuous annealing.
Key findings from this project include:
☑️ Demonstrates induction as a viable alternative to gas-fired AHSS annealing.
☑️ Achieves equal or higher fractions of retained austenite using rapid induction Q&P.
☑️ Uses rapid, higher-temperature partitioning to match conventional partitioning results in less time.
☑️ Produces refined microstructures with finer retained austenite grains for better formability.
Fluxtrol also sponsored the student competition at Heat Treat 2025, where Alec presented these results to the heat treating community, underscoring our commitment to advancing induction technology and supporting young engineers who are shaping the future of sustainable manufacturing. We would also like to gratefully acknowledge the support provided by the AIST Foundation and the sponsors of the ASPPRC, including Fives, U. S. Steel, Cleveland-Cliffs, Baosteel, and POSCO.

Product Spotlight: Soft Magnetic Composites for Advanced Induction Heating
Fluxtrol A
Fluxtrol 50
Alphaform LF
Fluxtrol offers a family of soft magnetic composites optimized for different frequency and loading conditions in induction coils.
Fluxtrol A provides high permeability and good saturation for demanding, medium-frequency applications; Fluxtrol 50 is tailored for higher frequencies where low losses and robust temperature resistance are critical; and AlphaForm LF is a formable, low-frequency material that can be shaped around complex coil geometries before curing, making it ideal for prototypes and intricate designs.
Together, these materials give coil designers flexible options to improve efficiency, heat pattern control, and component life across a wide range of induction heating and welding installations.
