The manufacturing method is characterized in that the high-conductivity low-Be bronze band contains Be less than 0.6 percent, Co and Ni less than 2.7 percent; in addition, the high-conductivity low-Be bronze band has low cost and saves costly metal Be, and can achieve the intensity of 900MPa and hardness of HV260 after ageing, which are second only to high-Be bronze; moreover, with the conductivity of 45 percent to 60 percent of IACS, the high-conductivity low-Be bronze band is one high-conductivity type in copper alloys and a good high-intensity and high-tenacity conductive and flexible material and can replace the high-Be bronze. The intensity of the high-conductivity low-Be bronze band is second to the high-Be bronze and is 1.5 times of common brass, and the conductivity is between 45 percent and 60 percent of IACS. Besides, according to different demands of customers, differentalloying components and processes are selected to change the properties of the material, and the changing range is larger so as to meet different demands, and the high-conductivity low-Be bronze band can be directly used in factories by hardening.
Description
Technical field
What the present invention relates to is a kind of manufacture method of high-conductivity low-beryllium bronze band, belongs to berylliumbronze manufacturing technology field.
Background technology
Berylliumbronze is divided into high strength berylliumbronze (1.7%～2.7%Be) and high-conductivity low-beryllium bronze (0.25%～0.8%Be) two big class, the existing both at home and abroad mass production of high berylliumbronze, intensity is up to 1300MPa after the timeliness, hardness reaches HRc43, it is the resilient material of a kind of outstanding high strength, high rigidity, wear-resisting, sparkless, conduction, of many uses, but its electric conductivity has only 22%I ACS, is restricted in the use of conductive switch, temperature controller, lead frame.In addition, beryllium is a nuclear reactor, the strategic materials that must use on rocket, the guided missile, and the price height makes the price height of high berylliumbronze, use is restricted.
Summary of the invention
The present invention proposes a kind of high-conductivity low-beryllium bronze band, is intended to replace high berylliumbronze band, reduces the consumption of beryllium, reduces material and electrical equipment cost, promotes the quality of electric equipment products.
Technical solution of the present invention: the manufacture method of high-conductivity low-beryllium bronze band is characterized in that joining the Cu-Be master alloy 47.2kg of 3.3%Be, cobalt metal 1.5kg, cathode copper 251.3kg.1250 ℃ of medium-frequency induction furnace meltings; 1250 ℃ of semicontinuous castings become 295kg slab ingot; after milling face; 900 ℃ of insulations 2 hours, hot rolling is worn the water quenching solid solution to 6mm is thick, and four-high mill is cold rolled to 2mm; 900 ℃ are incubated 1 hour; the entry solid solution is cold rolled to 1.0mm again, and 900 ℃ are incubated 1 hour; the entry solid solution; be rolled down to 0.35mm once more, through 900 ℃ of solution annealing of gas shield stove, 18% sulfuric acid washing; roll the 0.2mm finished product thickness; 2 hours nitrogen protection timeliness of 450 ℃ of insulations, carry out levelling machine smooth, deoil, be coated with BTA protection, check, packing warehouse-in.Finished product: 0.5%Be, 0.5%Co, Fe≤0.10, Al≤0.20, Si≤0.20, copper surplus, product performance: tensile strength 692MPa, unit elongation 19%, hardness HV215, electric conductivity 54%IACS.
Advantage of the present invention: high-conductivity low-beryllium bronze band contains Be below 0.6%, contain cobalt+nickel below 2.7%, cost is low, save valuable metallic beryllium, and the intensity after its timeliness can reach 900MPa, hardness HV260, be only second to high berylliumbronze, electric conductivity is at 45～60%IACS, it is the kind of high conductivity in the copper alloy, be good high strength, high tenacity, conductive elastomer, can be used widely, can replace high berylliumbronze in a large number at appliance field at automobile, motorcycle, electrical equipment, temperature controlled switch, CPU support lead, end points switch etc.Intensity is only second to high berylliumbronze in copper alloy, be more than 1.5 times of market brass, and especially electric conductivity is at 45-60%IACS.And the performance of selecting different alloying constituents and process system to change material according to user's service requirements, the scope of its change is bigger, applicable various requirement, factory's sclerosis is directly used, and the user needn't do ageing treatment by image height beryllium band again after punching press.
