Non-retentive alloy refers to a class alloy with low-coercivity and high magnetic permeability.Divide with the element of component alloy, mainly contain technically pure iron, FeSi alloy, FeNi alloy, FeAl alloy, FeSiAl alloy and FeCo alloy etc.; Divide by structure and have crystalline state and non-crystalline state.This type of alloy can be applicable in the elements such as electro-magnet, pole shoe, magnetic conductor, magnetic shielding, motor, transformer core, relay iron and wave filter.
Non-retentive alloy is in most cases applied under ac magnetization state, when frequency is higher, can produces eddy-current loss, cause alloy heat generating, and temperature raises, and magnetic property reduces.In order to reduce the eddy-current loss under high frequency, the resistivity of non-retentive alloy can be improved or reduce alloy size etc.
The non-retentive alloy with high resistivity mainly contains FeAl alloy, FeSiAl alloy and amorphous soft magnetic alloy.Though amorphous soft magnetic alloy has high resistivity, processing and manufacturing complex structure, larger-size block part cannot be gone out.In crystalline state non-retentive alloy, FeAl alloy and FeSiAl alloy have high resistivity, wherein the resistivity of FeAl alloy 1J12 (FeAl12%) and 1J16 (FeAl16%) is respectively 1.0 μ Ω m and 1.45 μ Ω about m, but the magnetic permeability of 1J12 alloy is lower, particularly initial permeability μ
0.4too low, be 0-2.0mH/m level, μ
0.8for the level of 2.5-6.9mH/m; Resistivity and the magnetic property of 1J16 and FeSiAl alloy are higher, but saturation induction density is all lower than 1.0T.When adopting 1J12,1J16 and FeSiAl alloy to make highpass filter, all service requirements cannot be met.
Liu great Jun disclosed the low remanent magnetism of a kind of high magnetic flux density high magnetic permeability high resistivity low-coercivity low density of material non-retentive alloy bar material (publication number CN1710941A) in 1998, main component is FeAl alloy, on the basis of Al content 11-14%, with the addition of 0-5%M (M is selected from Si, Mn, Ti, V, Cr, Mo, Nb, Ge, R (rare earth)) alloying element, this alloy is after vacuum melting, forging and thermal treatment, and performance can reach: μ
m=48.6mH/m, resistivity is 1.10 μ Ω m; 2005, Liu great Jun again disclosed a kind of non-retentive alloy bar and manufacturing process (publication number CN1718828A), and Al content is the FeAl alloy of 11-14%, and after vacuum melting, forging and thermal treatment, performance can reach: μ
0=4.5mH/m, μ
m=53mH/m, resistivity is 1.21 μ Ω m; Two kinds of alloys disclosed in above-mentioned patent, its initial permeability and maximum permeability all cannot meet the requirement of highpass filter.
