specific Embodiment approach 1

[0015] Specific Embodiment 1: This embodiment will be described in detail below. This embodiment is made of Si, Fe, Cu, Mn, Zn, Al, Mg and Ti, and the weight percentage of Si in the total composition is ≤0.04%, Fe The weight percentage of the total composition is 0.40% to 0.60%, the weight percentage of Cu to the total composition is 0.07% to 0.15%, the weight percentage of Mn to the total composition is 1.10% to 1.30%, and the weight percentage of Mg to the total composition is 0.02 % to 0.05%, the weight percentage of Zn in the total composition is ≤0.08%, the weight percentage of Ti in the total composition is 0.02% to 0.03%, and the rest is Al and impurities.

[0016] Mn content has a significant impact on the structure and properties of the alloy. Mn has a certain solid solution strengthening effect, which can prevent the recrystallization process of aluminum and aluminum alloys, increase the recrystallization temperature, and pass MnAl 6 Scattered particles hinder the gr...

specific Embodiment approach 2

[0022] Specific implementation mode two: the following specific description of this implementation mode, this implementation mode is completed by the following steps

[0023] A, smelting, using a gas reverberatory furnace to melt during smelting, and then transferring to a resistance reverberatory furnace according to the percentage by weight of Si in the total composition is ≤0.04%, the percentage by weight of Fe in the total composition is 0.40% to 0.60%, and Cu in the total composition The weight percentage of Mn is 0.07%-0.15%, the weight percentage of Mn in the total composition is 1.10%-1.30%, the weight percentage of Mg in the total composition is 0.02%-0.05%, the weight percentage of Zn in the total composition is ≤0.08%, Ti accounts for 0.02% to 0.03% by weight of the total composition, and the rest is Al and impurities. It is required to adjust the chemical composition, and at the same time add Al-Ti-B wire refiner to refine the grain, and carry out refining, degassin...

specific Embodiment approach 3

[0030] Embodiment 3: This embodiment will be described in detail below. In this embodiment, an annealing process is inserted in step F, and other steps are the same as in Embodiment 2.

Abstract

Alloy plate trip for the battery case of mobil telephone and its preparation method is disclosed, in order to solve the problem that the alloy plate trip for the existing battery case of mobil telephone has poor stamping properties and the quality defect of the alloy is easy to be caused because of the complex arts. The alloy plate trip for the battery case of mobil telephone of the invention comprises Mn, which is 1.10-1.30 wt.% of overall composition, and Mg, which is 0.02-0.05 wt.% of overall composition. The method for preparing the alloy plate trip for the battery case of mobil telephone of the invention includes the steps of: smelting, casting, uniformizating, face milling, hot rolling, cold rolling and final finishing. The alloy plate trip for the battery case of mobil telephone of the invention has good-quality surface, high-precision thickness and good stamping properties, and all kinds of properties of the plate trip is steady with high intensity and higher plasticity and good deep punching moldability, and the quality defect of the alloy can be reduced effectively in case that the preparation method is simpler than traditional method.

Description

technical field [0001] The invention relates to an alloy plate and strip material for a mobile phone battery case and a manufacturing method thereof. Background technique [0002] my country is already the world's largest producer and consumer of mobile communication terminals. According to the statistics of the Ministry of Information Industry, my country currently has nearly 1 / 3 of the global mobile phone production and about 1 / 5 of the sales market, and is the most important mobile phone production and sales center in the world. According to statistics, by the end of 2004, the penetration rate of mobile phones in my country has exceeded 25%. It can be seen that the mobile phone market in my country has great potential. As one of the most dynamic telecommunication terminals, the mobile phone has undergone great changes since its birth. Multi-function, personalization, and miniaturization are the development trends of mobile phones in the future. As the power device for m...
