Embodiment 1

[0027] Embodiment 1 aluminum alloy material MH-03 and preparation method thereof

[0028] An aluminum alloy material in this embodiment is prepared from the following components in weight percentage: Al90.2649%, Si2.26%, Fe0.276%, Cu0.0465%, Mn0.737%, Mg6.1 %, Cr0.135%, Ni0.0035%, Zn0.0783%, Ti0.0712%, Bi0.0045%, Ca0.0012%, Cd<0.001%, Sn0.0070%, Zr0.0017%, Pb0.0132 %.

[0029] The preparation method of the aluminum alloy material of this embodiment comprises the following steps:

[0030] 1. Loading

[0031] During smelting, the order and method of charging the charge not only affect the smelting time, metal burning loss, and heat energy consumption, but also affect the quality of the metal melt and the service life of the furnace. The principles of loading are:

[0032] a. The order of charging the furnace materials should be reasonable. The correct charge depends on the nature and state of the charged charge, and should also take into account the fastest melting speed, ...

Abstract

The invention discloses a high-end aluminium alloy material MH-03. The high-end aluminium alloy material MH-03 comprises the following components: 89.0-91.0% of Al, 1.8-3.5% of Si, less than 0.50% of Fe, less than 0.2% of Cu, 0.55-1.0% of Mn, 4.8-6.5% of Mg, less than 0.3% of Cr, less than 0.07% of Ni, 0.05-0.1% of Zn, less than 0.2% of Ti, less than 0.005% of Bi, less than 0.002% of Ca, less than 0.1% of Pb, less than 0.05% of Sn, less than 0.005% of Bi, and less than 0.001% of Cd. The high-end aluminium alloy material MH-03 disclosed by the invention has higher tensile strength, specified plastic extension strength, percentage elongation after fracture, elasticity modulus and Brown hardness; the content of harmful substances is extremely low, and far lower than the limit value of 2001 / 65 / EU instructions; and the high-end aluminium alloy material MH-03 is simple in preparation process, and suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of high-end electronic materials. Specifically, the invention relates to a high-end aluminum alloy material used for a smart phone shell, middle frame and frame and a preparation method thereof. Background technique [0002] The biggest advantage of metal material is of course that it can make the product have the unique luster and touch of metal. The unique cold and delicate touch of metal comes from its good thermal conductivity and dense atomic arrangement structure, while the beautiful metallic luster is because the free electrons inside the metal absorb the external light and then release most of the light. visible light. [0003] In the prior art, the metal materials used for the casing, middle frame and frame of smartphones are usually S33N, S36-V4 and other materials, which have defects in tensile strength, hardness, elongation after fracture, and elastic modulus. The composition of materials is im...
