Problems solved by technology

For example, mobile phone protective cases made of stainless steel or titanium alloy often release nickel, and the amount of nickel released is relatively large, which can easily cause skin allergies for mobile phone users
[0006] In addition, the mobile phone protective case made of stainless steel or titanium alloy in the prior art, because some of them contain toxic beryllium element, will release toxic beryllium during long-term use and penetrate into the skin of the mobile phone user, thereby harmful to human health

Abstract

The invention relates to the technical field of applications of amorphous alloys and in particular relates to an amorphous alloy protective shell for a mobile phone and a manufacturing method of the amorphous alloy protective shell. The amorphous alloy protective shell for the mobile phone is manufactured by a zirconium-based amorphous alloy, a copper-based amorphous alloy, a titanium-based amorphous alloy, a nickel-based amorphous alloy, a palladium-based amorphous alloy or an iron-based amorphous alloy. The manufacturing method of the amorphous alloy protective shell for the mobile phone comprises the following steps: preparing the amorphous alloy protective shell for the mobile phone by carrying out a die-casting molding method, a melt-spinning method, a suction casting method, a rapid discharge formation method, a continuous casting method or a thermoplastic formation method on an alloy ingot of the amorphous alloy. The amorphous alloy protective shell for the mobile phone has the advantages of high strength, high rigidity, high elasticity, abrasion, scraping and corrosion resistance, beauty, long service life and capability of avoiding the bending phenomenon when the mobile phone is largely stressed.

Description

technical field [0001] The invention relates to the technical field of application of amorphous alloys, in particular to an amorphous alloy mobile phone protective case and a manufacturing method thereof. Background technique [0002] At present, for the purpose of good appearance and light weight, aluminum alloy is often used as the material for the casing of the smart phone itself. However, due to the low strength of the aluminum alloy, such a mobile phone with an aluminum alloy casing is prone to bending when subjected to a large force during use, thereby causing damage to the mobile phone. [0003] Therefore, people protect the mobile phone by putting on a mobile phone protective case on the mobile phone case. In the prior art, the materials of mobile phone protective cases are mostly leather, silica gel, cloth, hard plastic, soft plastic, velvet, and silk. These protective cases have the disadvantages of being not wear-resistant, not scratch-resistant, and have a short...
