Embodiment 1

[0047] A tin-phosphorus-zinc-copper alloy, the percentage by weight of each element is as shown in Table 1 below;

[0048] A preparation method of tin-phosphorus-zinc-copper alloy, comprising the following steps:

[0049] 1) Configure 1500g sample as an example to calculate: 99.9% electrolytic copper sheet should be added to the precision melting furnace with a ratio of 79.630%, that is, 1500g×79.630% = 1194.45g, because the amount of copper added to the phosphor-bronze master alloy needs to be deducted, the actual addition It is: 1194.45g-43.875g=1150.575g electrolytic copper sheet, heat up at a rate of 10°C / min, heat up to 1280-1380°C, add 0.325% phosphorus, that is, add phosphorus copper master alloy containing 10% phosphorus, that is, 1500×0.325 % / 0.1=48.75g phosphor-bronze master alloy (the copper content is 48.75-4.875=43.875g), after reaching the temperature of 1280-1380°C, stir and maintain for 10min.

[0050] 2) Weigh 0.300% nickel metal in proportion, that is, 4.5g,...

Abstract

The invention discloses a zinc tin phosphor copper alloy and a preparing method thereof. The alloy comprises, by weight percent, 0.095 to 10.000% of tin, 10 to 22% of zinc, 1 to 7% of aluminum, 0.05 to 0.20% of beryllium, 0.10 to 0.40% of phosphor, 0.3% of nickel and the balance copper. Compared with the prior art, metal beryllium is added, alloy strength is greatly improved, the use amount of zinc can be greatly increased, the alloy cost is reduced, the amount of traditional zinc ranges from 0.05 to 5%, the zinc ranges from 10 to 22%, the maximum cost is reduced by 19.36%, and the zinc tin phosphor copper alloy is excellent in property. The stretching strength is up to 775.6MPa, the elongation reaches 36.5%, and the hardness reaches 206HV.

Description

technical field [0001] The invention relates to the field of copper alloys, in particular to a tin-phosphorus-zinc-copper alloy and a preparation method thereof. Background technique [0002] Tin-phosphorus bronze alloy has excellent qualities such as high strength, high elasticity, good wear resistance, and good corrosion resistance. Its strips and other products and parts have good electrical and thermal conductivity, as well as intentional elasticity and fatigue resistance. Its application range is very wide, covering many fields such as modern science and technology aerospace, aviation, navigation, electronics, telecommunications, atomic energy, instrumentation, construction, civil use, etc. With the progress of human society, the development of these fields requires an increasing demand for such materials. [0003] In sharp contrast to the ever-increasing demand, there is a serious shortage of copper resources. Actual data show that the development speed of copper reso...
