Abstract
A kind of corrosion-resistant easy welding silicon bronze band preparation method, by weight percentage, it is characterised in that: fluorine that the copper alloy contains 0.35%~0.9% Cr3C2,3.15-3.55%, oxygen≤0.10%, calcium 0.45-0.9%, boron 2.10-2.65%, chromium 0.20-0.40%, in alloy can also include a certain amount of Zr and rare earth at nitrogen≤0.16%.Its low price, high-precision, high yield anti-corrosion material, especially at high temperature, have very high hardness, substantially increase the wearability with contact surfaces such as welding wires.The present invention can produce high-precision, the ignition tip of high yield, electrode cap.Its low price, high-precision, high yield anti-corrosion material, comprehensive performance has reached the ideal main performance index of super large-scale integration blaster fuse frame material.
Description
Technical field
The present invention relates to the application fields of steel alloy, weld silicon bronze band preparation side especially with respect to a kind of corrosion-resistant easy
Method.
Background technique
In the market, the elastic material that high-end product uses is silicon bronze alloy to current elastic alloy, and the material is corrosion-resistant
Performance is good, and tensile strength is high, is able to satisfy part requirement completely, but the price is very expensive.Per kilogram makes at 1800 yuan or so
The cost for obtaining product is very high.Although many well-known manufacturers do in the performance for improving and stablizing elastic material such as 3J21 alloy
It is many to work but do not solve the problems, such as inherently the alloy in quality, present on use.It is, for example, less than that predetermined size twines
Around test, the embrittlement problem of same upper forward and reverse 90-degree bent of practising physiognomy, the further development and application of the alloy is also limited.
Summary of the invention
In order to solve above-mentioned problem, the purpose of the present invention is to provide a kind of corrosion-resistant easies to weld silicon bronze band preparation side
Method is suitably added to the chromium that China has resources advantage in known formulations, while improving technique, reduces N (nitrogen) O (oxygen)
Content fullys meet the performance indexes of similar products at home and abroad.
The technical scheme is that be accomplished by the following way: a kind of corrosion-resistant easy welding silicon bronze band preparation side
Method, by weight percentage, it is characterised in that: the copper alloy closes the Cr for having 0.35%~0.9%3C2, 3.15-3.55%
Fluorine, oxygen≤0.10%, calcium 0.45-0.9%, boron 2.10-2.65%, chromium 0.20-0.40%, may be used also in alloy at nitrogen≤0.16%
To include a certain amount of Zr and rare earth.
A kind of corrosion-resistant easy welding silicon bronze band preparation method, comprising the following steps: in the case where temperature is 940~980 DEG C
It carries out solutionizing processing and temperature is to carry out ageing treatment at 430~470 DEG C；It can further include spray to cast method preparation Cu-
Cr3C2Treatment process after-Zr- rare earth alloy technology and alloy spray to cast obtains existing very high hardness, conductivity, and has
There is the silicon bronze steel of good machinability.
The present invention can produce high-precision, the ignition tip of high yield, electrode cap.Its low price, high-precision, Gao Chengcai
The anti-corrosion material of rate especially at high temperature has very high hardness, substantially increases the wearability with contact surfaces such as welding wires.
Electric property with higher and hardness, it is ideal that comprehensive performance has reached super large-scale integration blaster fuse frame material
Main performance index.
Specific embodiment
A kind of corrosion-resistant easy welding silicon bronze band preparation method, by weight percentage, it is characterised in that: the copper closes
The Cr of Jin Heyou 0.35%~0.9%3C2, the fluorine of 3.15-3.55%, nitrogen≤0.16%, oxygen≤0.10%, calcium 0.45-0.9%,
It boron 2.10-2.65%, chromium 0.20-0.40%, in alloy can also include a certain amount of Zr and rare earth.
A kind of corrosion-resistant easy welding silicon bronze band preparation method, comprising the following steps: in the case where temperature is 940~980 DEG C
It carries out solutionizing processing and temperature is to carry out ageing treatment at 430~470 DEG C；It can further include spray to cast method preparation Cu-
Cr3C2Treatment process after-Zr- rare earth alloy technology and alloy spray to cast obtains existing very high hardness, conductivity, and has
There is the silicon bronze steel of good machinability.
The hardness and conductivity relationship no-float of copper alloy may be implemented in the present invention, while hardness and conductivity can be with bodies
Existing higher temperature stability, and there is good machinability, high-precision, the ignition tip of high yield, electrode can be produced
The metalworks such as cap.
