Abstract
The present invention relates to a kind of high-strength high-conductive chromium-copper, the copper alloy contain 0.35%~0.9% Cr3C2,3.15~3.55% carbon, sulphur≤0.16%, phosphorus≤0.10%, manganese 0.45~0.9%, silicon 2.10~2.65%, chromium 0.20~0.40%, a certain amount of Zr and rare earth can also be included in alloy, the present invention, high accuracy, the ignition tip of high yield, electrode cap can be produced.Its low price, high accuracy, the anti-corrosion material of high yield, particularly at high temperature, there is very high hardness, substantially increase the wearability with the contact surface such as welding wire.
Description
Technical field
The present invention relates to the application field of steel alloy, concretely relates to a kind of high-strength high-conductive chromium-copper.
Background technology
Current elastic alloy in the market, the elastomeric material that high-end product uses are cobalt-based 3J21 alloys, the material corrosion resistant
Corrosion can be good, and tensile strength is high, is entirely capable of meeting part requirement, but price is sufficiently expensive.Per kilogram at 1800 yuan or so,
So that the cost of product is very high.Although many well-known manufacturers do in the performance of raising and stable elastomeric material such as 3J21 alloys
Many work but do not solve the alloy inherently in quality, problem present on use.It is, for example, less than given size
Wrapping test, the embrittlement problem of same upper forward and reverse 90-degree bent of practising physiognomy, also limit the further development and application of the alloy.
The content of the invention
A kind of high-strength high-conductive chromium-copper is provided it is an object of the invention to solve above-mentioned technical problem.
To achieve the above object, the present invention uses following technical scheme：
A kind of high-strength high-conductive chromium-copper, by weight percentage, it is characterised in that：The copper alloy contains 0.35%
~0.9% Cr3C2,3.15~3.55% carbon, sulphur≤0.16%, phosphorus≤0.10%, manganese 0.45~0.9%, silicon 2.10~
2.65%th, a certain amount of Zr and rare earth can also be included in chromium 0.20~0.40%, alloy.
The present invention, high accuracy, the ignition tip of high yield, electrode cap can be produced.Its low price, high accuracy, height are become a useful person
The anti-corrosion material of rate, particularly at high temperature, there is very high hardness, substantially increase the wearability with the contact surface such as welding wire.
With higher electric property and hardness, it is preferable that its combination property has reached super large-scale integration blaster fuse frame material
Main performance index.
Embodiment
Below, the substantive distinguishing features and advantage of the present invention are further described with reference to example, but not office of the invention
It is limited to listed embodiment.
A kind of high-strength high-conductive chromium-copper steel, by weight percentage, it is characterised in that：The copper alloy contains
0.35%~0.9% Cr3C2,3.15~3.55% carbon, sulphur≤0.16%, phosphorus≤0.10%, manganese 0.45~0.9%, silicon
2.10~2.65%, a certain amount of Zr and rare earth can also be included in chromium 0.20~0.40%, alloy.
The present invention can realize the hardness and conductance relation no-float of copper alloy, while hardness and electrical conductivity can be with bodies
Now higher temperature stability, and there is good machinability, high accuracy, the ignition tip of high yield, electrode can be produced
The metalworks such as cap.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
