Abstract
The present invention discloses a composite metal material with a zero magnetic property. The composite metallic material is formed by using copper, zinc and nickel as raw materials, and the copper, the zinc and the nickel are Chinese standard 1<#> or 2<#> copper, zinc and nickel. The ratio of the copper to the zinc to the nickel is 6 to 1.5 to 2.5. According to the ratio, the nickel, the copper and the zinc are orderly thrown into an industrial medium-frequency induction furnace to melt; then, the melted liquid of the raw materials is tested by an inductive type metal detector; if the melted liquid is eligible, the melted liquid is tapped off and directly cast and molded. The composite metal material with a zero magnetic property of the present invention has an improved processing property and an improved service property; the composite metallic material not only has the metallic electrical conductivity, but also has the zero magnetic property, namely that when the melted liquid is tested by the inductive type metal detector, the melted liquid has no magnetism to the inductive type metal detector; underground objects made of the material of the present invention can not be discovered by the inductive type metal detector; electronic components made of the material of the present invention does not affect the electromagnetism signals of external circuits in a certain area, and thus, the material of the present invention is a novel application material in the military industry and the electronic information industry.
Description
Technical field
The present invention relates to a kind of composite material, particularly relate to a kind of composite metal materials without magnetism that hidden material, shielding material, intelligent material and new electronic component are made the field that is widely used in.
Background technology
Various metals all have the magnetic properties of oneself, and it shows as ferromegnetism, paramagnetism and diamagnetism, are ferromagnetic metal as iron, nickel; Copper, zinc are the diamagnetism metal; Aluminium is paramagnetic metal, thereby can exert an influence to foreign field and electromagnetic signal, can't resolve metal self the zero magnetic properties problem in hidden and responsive field.Zero magnetic of existing metallic substance or nonmagnetic is foundation with magnetic field force to the effect degree of its material all, and when with the induction type metal locator it being detected, then the induction type metal locator responds, and shows that having metallic substance now does not have zero magnetic property.
Summary of the invention
The objective of the invention is provides a kind of composite metal materials without magnetism for overcoming disadvantages of background technology.A kind of composite metal materials without magnetism that the present invention produces had both had the conductivity of metal, had induction type metal locator unresponsive zero magnetic property when it is surveyed again.
For achieving the above object, the technical solution used in the present invention is: a kind of composite metal materials without magnetism is characterized in that: it is to be the matrix material that raw material is made by copper, zinc and nickel, and the copper that is adopted, zinc and nickel are GB 1

#Copper, zinc and nickel, its ratio: copper: zinc: nickel is 6: 1.5: 2.5.
Its manufacturing process is: with GB 1
#Or 2
#Copper ingot, zinc ingot metal and nickel ingot or its section bar, after oxide on surface and impurity cleaned out, melt with industrial intermediate frequency induction furnace, by copper: zinc: nickel is earlier to drop into nickel at 6: 1.5: 2.5, drop into copper when treating its fusing again, drop into zinc at last, treat that the three is fully melted after, the insulation 25～30min, between soak, the liquation that takes a morsel extremely high temperature resistant saggar is treated to remove surface irregularities behind its naturally cooling as the product of detection, and CT-900 detects with the induction type metal locator, when induction type metal locator CT-900 is not qualified during sounding near detecting product, detect with the digital display type metal locator again during as sounding, when the detector demonstration is negative partially, in stove, add 1.5% with interior nickel, when detector shows polarization, in stove, add 4% with interior copper, be shown as zero to detector after, liquation is come out of the stove and the direct pouring moulding.
Copper is a kind of incarnadine and glossiness metal, strong but pliable in texture, rich ductility and very high heat conduction and conductivity are arranged, not by attraction, belong to the diamagnetism metallic substance, 1083 ℃ of fusing points, stable in dry air, but in the wet air of carbonic acid gas is arranged, easily generate verdigris on the surface, be insoluble to hydrochloric acid or dilute sulphuric acid, be dissolved in nitric acid and hot concentrated sulfuric acid, meet alkali and easily be corroded; Zinc is a kind of cream white metal, and stable in the air, chemical property is more active, makes the time spent releasing hydrogen gas with acid or alkali, has both sexes, not by attraction, belongs to the diamagnetism metallic substance, 419.58 ℃ of fusing points; Nickel is a kind of silvery white metal, and is very hard, and rich ductility can be belonged to ferromagnetic metal material by attraction, and 1455 ℃ of fusing points have good erosion resistance, and are not oxidized in air, and anti-highly basic is slow with hydrochloric acid and effect of sulfuric acid, but is dissolved in nitric acid.
Advantage of the present invention is: a kind of composite metal materials without magnetism that the present invention produces, processing performance improves, the conductivity that had both had metal, has induction type metal locator unresponsive zero magnetic property when it is surveyed again, utilize material of the present invention to make underground object, can not find by sensed formula metal locator, utilize material of the present invention to make electronic devices and components, can not influence the electromagnetic signal of external circuit within the specific limits, be the new application material that military project and e-mail are suffered from industry.
