Browse our high-performance permanent magnets engineered to extreme tolerances for industrial motors and global OEM applications.
Ticonal permanent magnets are manufactured through a sophisticated heat-treatment process within a strong magnetic field. This induces spinodal decomposition, aligning precipitate microstructures along a preferred magnetic axis, maximizing remanence (Br) and energy product (BH)max in the orientation direction.
With a Curie temperature exceeding 850°C and a maximum service ceiling of 525°C to 550°C, Ticonal exhibits a tiny temperature coefficient of remanence (approximately -0.02%/°C). It is uniquely suited for precise applications running under highly volatile thermal conditions.
Because Ticonal magnets possess lower coercivity (Hc) compared to rare-earth alloys, custom engineering requires meticulous attention to the length-to-diameter (L/D) ratio. Our engineers utilize advanced finite element analysis (FEA) to secure your system against self-demagnetization.

Ticonal magnets (a type of Alnico) offer lower magnetic strength (energy product) but exceptional temperature resistance (up to 550°C) and low temperature coefficients. Neodymium (NdFeB) magnets deliver high magnetic fields at room temperature but suffer significant magnetic degradation above 80°C to 200°C.
Due to its low intrinsic coercivity (Hc), a Ticonal magnet can easily demagnetize itself if not designed properly. A high length-to-diameter (L/D) ratio utilizes the magnet's geometry to establish a favorable permeance coefficient, maintaining the magnetic field stability.
We provide full-scope OEM support, including 2D/3D technical drawings, mechanical tolerance machining down to ±0.01mm, magnetic orientation customization (axial, radial, multi-pole), high-stability coating applications, and testing reports.
We utilize advanced testing tools, including demagnetization curve tracers (hysteresisgraphs), ICP-OES spectrometers for chemical verification, Helmholtz coils with fluxmeters, 3D coordinate measuring machines (CMM), and environmental chambers for salt spray and thermal cycling.
For prototype samples, lead times typically run 10 to 15 business days. Commercial volume production batches are completed within 20 to 30 days, depending on geometry complexity, plating specifications, and raw material status.
We provide multiple protective coatings to prevent oxidation and chemical degradation, including multi-layer Nickel-Copper-Nickel (Ni-Cu-Ni), Epoxy resin (black or grey), Zinc (Zn), Gold (Au), Parylene, and specialized plastic/rubber overmolding.
