Product Description

Physical parameter

The physical parameters of amorphous cores are the core features that distinguish them from traditional crystalline cores. These parameters are determined not only by the disordered arrangement structure of atoms in amorphous materials but also directly affect their electromagnetic properties and application scenarios. The following is a detailed analysis of the key physical parameters of amorphous cores from the dimensions of material properties, electromagnetic performance, thermal characteristics, etc.

Basic physical parameters of materials

Amorphous structure: The atomic arrangement has no long-range order (different from the grain structure of silicon steel sheets), the defect density is low, there is no grain boundary resistance, and the resistance to the movement of magnetic domain walls is reduced. • Alloy composition: Common compositions include iron-based (Fe), boron (B), silicon (Si), carbon (C), etc. (such as Fe78Si9B13). Some high-end products add cobalt (Co) and nickel (Ni) to optimize magnetic permeability.

Geometric and mechanical parameters: • Strip thickness: Typical values are 0.015-0.03mm (traditional silicon steel sheets are 0.1-0.5mm), and the ultra-thin design reduces eddy current losses. • Density: Approximately 7.1-7.3g/cm³ (lower than the 7.6-7.8g/cm³ of silicon steel sheets), facilitating the lightweight of equipment. • Hardness: The Vickers hardness (HV) is approximately 800-1100, which is higher than that of silicon steel sheets (HV 180-300). It has strong wear resistance but is brittle during processing.

Core parameters of electromagnetic performance

Magnetic permeability (μ) • Initial magnetic permeability (μi) : The magnetic permeability in the absence of an external magnetic field. Amorphous cores can reach the order of 10000 - 100000(about 10³ - 10000 for silicon steel sheets), and the magnetic response is faster at high frequencies. • Maximum magnetic permeability (μmax) : It can reach 10000 - 1000000, making the movement of magnetic domain walls easier and suitable for high-sensitivity applications under weak magnetic fields (such as current transformers).

Iron loss (Pfe) • Definition: 

The energy loss per unit weight of an iron core under an alternating magnetic field, which is a core indicator for measuring energy efficiency. • Typical values:Under the operating conditions of 10 KHZ and 1.0T, the iron loss is approximately 0.1-0.5W/kg (while traditional silicon steel sheets can reach 1-3W/kg). The advantage is more significant at high frequencies (100kHz), and the increment of iron loss is much lower than that of silicon steel sheets.

The saturated magnetic induction intensity (Bs)

The saturated magnetic induction intensity (Bs) of amorphous cores is typically 1.2-1.5T (1.6-1.8T for silicon steel sheets), slightly lower than that of traditional materials, but can be increased to over 1.8T through composition optimization (such as adding cobalt).

Coercive force (Hc)

Resistivity (ρ)

Thermology and environmental parameters

Coercive force (Hc) : The Hc of amorphous cores is extremely low, generally ranging from 0.1 to 1A/m (1 to 10A/m for silicon steel sheets), with a small hysteresis loop area and low hysteresis loss, making it suitable for repeated magnetization scenarios.

Resistivity (ρ) is approximately 110-130μΩ · cm (40-60μΩ · cm for silicon steel sheets). High resistivity reduces eddy current losses, especially with obvious advantages in high-frequency operating conditions.

Curie Temperature (Tc) : The Tc of iron-based amorphous cores is approximately 410-450 ℃. Beyond this temperature, the magnetic properties significantly decline (the operating temperature of the equipment needs to be controlled below 120℃). 2. The coefficient of thermal expansion is approximately 11-13 ×-1000000/℃, which is close to that of conductive materials such as copper and aluminum, and has good thermal compatibility, reducing thermal stress deformation. 3. Corrosion resistance: The surface of amorphous alloys is prone to form an oxide film, and their resistance to atmospheric corrosion is superior to that of silicon steel sheets. However, long-term contact with acidic media should be avoided.
