Description
Technical field
The present invention relates to copper processing techniques fields, more particularly, to a kind of fuse cap copper alloy and production technology.
Background technique
Fuse cap needs strongly tensile, while conductivity requirements are high (80% or more), and fine copper conducts electricity very well but strongly tensile
Easy fracture (elongation percentage 30-40%), alloyed copper such as brass tensile property is good but conductivity is low (conductivity 30% is even lower), very
Difficulty is met the requirements；Existing complex production process, it is at high cost.
Summary of the invention
In view of the shortcomings of the prior art, technical problem to be solved by the invention is to provide a kind of fuse cap copper alloy with
And production technology, it can reach the conductivity requirements of fuse cap, and there is good tensile property.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is as follows:
A kind of fuse cap copper alloy, the fuse cap copper alloy include following chemical component and quality percentage
Than: Cu >=99.92%, P:0.008-0.025%, Fe:0.002-0.010% and inevitable impurity.
Preferably, copper alloy includes following chemical component and mass percent: Cu99.94%, P:0.015%, Fe:
0.006% and inevitable impurity.
The content of the P are as follows: 0.012-0.020%.
The content of the Fe are as follows: 0.005-0.009%.
A kind of production technology of fuse cap copper strips, comprising the following steps:
Material composition allotment-casting obtain slab-milling face-roughing-annealing-being rolled in cleaning-- anneal-clean-finish rolling-moves back
Fire-cleaning+passivation-is cut-is packed and stored.
A kind of production technology of the copper strips processing fuse cap using production, comprising the following steps:
Finished product-punch forming is dried-is stretched in copper strips-stretching semi-finished product-annealing-cleaning+.
Compared with prior art, the present invention having the advantage that the fuse cap copper alloy and production technology balance
Relationship between conductivity and tensile property can reach the conductivity requirements of fuse cap, and have good tensile property；
And it is at low cost, it is easy to process.
Specific embodiment
By the description of the embodiment, specific embodiments of the present invention will be described in further detail.
The fuse cap copper alloy, including following chemical component and mass percent: Cu >=99.92%, P:0.008-
0.025%, Fe:0.002-0.010% and inevitable impurity.
Further, the content of P are as follows: the content of 0.012-0.020%, Fe are as follows: 0.005-0.009%.The allotment of its ingredient
The performance produced of raw material it is more preferable.
Preferably, copper alloy includes following chemical component and mass percent: Cu99.94%, P:0.015%, Fe:
0.006% and inevitable impurity.
The production technology of fuse cap copper strips, comprising the following steps:
Material composition allotment-casting obtain slab-milling face-roughing-annealing-being rolled in cleaning-- anneal-clean-finish rolling-moves back
Fire-cleaning+passivation-is cut-is packed and stored.
Utilize the production technology of the copper strips processing fuse cap of production, comprising the following steps:
Finished product-punch forming is dried-is stretched in copper strips-stretching semi-finished product-annealing-cleaning+.
By the allotment to ingredient, obtaining a kind of copper master alloy, it is necessary to have low costs, the characteristic of easy processing；It balances
Relationship between conductivity and tensile property should reach the conductivity requirements of fuse cap, have good draftability again
Energy；Crystal grain is tiny, stretches phenomena such as rear surface is without pitted skin, point.
The fuse cap copper band of production, conductivity >=80%, due to alloyed copper；Tension >=240MPa extends >=40%,
Performance is substantially better than traditional handicraft, and product quality greatly improved.
And cost of material, production cost are not higher than the cost of existing fine copper, do not increase the purchase cost of client；Punching is protected
Double annealing is not needed during dangerous silk cap, production efficiency and lumber recovery is greatly improved, reduces processing cost.
The contrast table of 1 ingredient of table/mechanical property and conductivity (by taking 0.5M finished product as an example)
The fuse cap copper alloy and production technology balance the relationship between conductivity and tensile property, can reach
The conductivity requirements of fuse cap, and there is good tensile property；And it is at low cost, it is easy to process.
It above are only and preferred embodiments of the present invention are illustrated, above-mentioned technical characteristic can form multiple hairs in any combination
Bright example scheme.
