Features of Nickel iron molybdenum sofmag80 hymu80 core permalloy 80 rod
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of Nickel iron molybdenum sofmag80 hymu80 core permalloy 80 rod
Nickel-iron-molybdenum soft magnetic alloy, specifically the Hymu80 and Sofmag80 cores, are advanced materials used in various applications requiring high magnetic permeability and low coercivity. These core materials are designed to maximize efficiency and minimize energy losses in electromagnetic devices, such as transformers, inductors, and motors.
Hymu80 is a composition that combines nickel, iron, and molybdenum, offering a unique balance of properties. Nickel provides good saturation magnetization, while iron contributes to the overall magnetic strength. Molybdenum acts as a strengthening element, enhancing the alloy’s mechanical properties and resistance to corrosion. The result is a material with a high magnetic permeability (around μ = 800), which allows for efficient flux control and minimal magnetic hysteresis, making it ideal for situations where rapid magnetic field changes are required.
Sofmag80, on the other hand, is another variant of this family, also known as permalloy. Permalloy is a trademarked term for a specific type of nickel-iron alloy, typically containing around 80% nickel and 20% iron. This material is characterized by its excellent soft magnetic properties, low coercivity (the force needed to demagnetize the material), and high electrical conductivity. The combination of these features makes Sofmag80 an excellent choice for applications like magnetic shielding, transformers, and microwave components, where low loss and fast response times are crucial.
Both Hymu80 and Sofmag80 cores have a low saturation induction (Bsat), which means they can easily saturate under moderate magnetic fields, further contributing to their energy-saving capabilities. Their high thermal stability ensures they can maintain their performance over a wide temperature range, making them suitable for applications subjected to varying environmental conditions.
The manufacturing process of these rods involves careful control over the chemical composition and microstructure to achieve the desired properties. They are typically produced using techniques like casting, sintering, or powder metallurgy, followed by heat treatment to optimize the grain structure and enhance the magnetic properties.
In summary, Nickel-iron-molybdenum soft magnetic alloys, particularly Hymu80 and Sofmag80, are high-performance materials with exceptional magnetic properties. Their combination of high permeability, low coercivity, and thermal stability make them indispensable in modern electronic and electromechanical systems where efficiency, responsiveness, and durability are critical factors. The availability in the form of rods ensures easy integration into various component designs, contributing to the overall functionality and effectiveness of the final product.
