Then it pressurizeing to the core blank in pressurizing mold, pressure is 5MPa~8MPa, and 10~15min of pressure maintaining is cooled to room temperature,
Take out core blank；
(C) core blank obtained in step (B) is heated to 90 DEG C~110 DEG C by destressing, keeps the temperature 60~80min,
It is then cooled to room temperature；And
(D) layers of copper is electroplated, and carries out electro-coppering to the surface of core blank obtained in step (C), copper plate with a thickness of
0.10~0.15mm.
An embodiment according to the present invention, the core molding and the core densification of the step (B) of the step (A) are in hydrogen
Compression ring is completed under border, and hydrogen pressure is not more than 6000Pa.
An embodiment according to the present invention, iron, copper, aluminium, magnesium, scandium in the step (A) are powder, and granularity is not more than
350 mesh.
The present invention compared with the existing technology, mainly has the following advantages and beneficial effects:
(1) in core material, tin is low-melting-point metal, about 231 DEG C of fusing point, is easy fusing and fusing, the electric conductivity of copper
Can be good, copper is added, alloy melt is made to have good electric conductivity when unblown, in addition, the addition of copper can also improve conjunction
The intensity of golden melt；The addition of iron, so that alloy melt, when by larger current, local temperature is higher inside melt, at this moment
Iron can form alloy with tin, and copper can form alloy with aluminium, and magnesium can form alloy with tin, and resistance becomes larger, to accelerate to close
The fusing of golden melt, in addition, the addition of iron, can also reduce the cost of alloy melt；
(2) in preparation step (A), Sn is heated to 520~550 DEG C, the significantly larger than fusing point of Sn, is improved Sn's
Activity, so that the combination of Sn and Cu, Fe are improved, since Sn can form metallic compound, heating temperature at 550 DEG C or more with Fe
Degree should be not more than 550 DEG C；The step (A) and step (B) need to be completed under hydrogen environment, and hydrogen pressure is not more than 6000Pa,
It is that can generate oxide since Sn, Fe are when temperature is higher, the oxide of generation will affect the performance of alloy melt；It is added
Sc can be reacted with oxygen and impurity, purify matrix, and the oxygen that in addition a small amount of hydrogen can adhere to surfaces such as Fe, Cu carries out anti-
It answers, removes the oxygen on surface；
(3) in preparation step (B), core blank is put into pressurizing mold, certain temperature repressurization is heated to, is able to
The consistency for improving alloy melt, achievees the purpose that further increase intensity；
(4) in preparation step (C), destressing is able to the stress inside removal alloy melt, to extend alloy melt
Service life；
(5) since the surface in Sn is difficult direct copper plating, Cu, the Fe being added in core have with electro-coppering good
Compatibility can improve the plating performance of alloy melt, be able to carry out electricity directly on the core of alloy melt after Cu, Fe is added
Plating；Wherein, copper plate is able to that alloy melt is effectively prevent to aoxidize, and avoids being chronically exposed in air and aoxidizing, to influence molten
Bulk resistor；Copper plate cannot be too thick, and the too thick alloy melt that will lead to is difficult to break；Can not be too thin, coating is too thin, is transporting or is making
With when, layers of copper be easy polishing；Further, since the intensity of copper is greater than the intensity of tin, copper plate is also increased alloy melt
Intensity.
