Impact-resisting and scratching-resisting mobile phone metal back shell

Abstract

An impact-resisting and scratching-resisting mobile phone metal back shell is characterized in that the impact-resisting and scratching-resisting mobile phone metal back shell is prepared from the following components of, by weight, 5-15 parts of magnesium powder, 5-10 parts of titanium powder, 5-15 parts of hard alloy materials, 10-25 parts of brass, 8-18 parts of iron alloys, 8-18 parts of austenitic stainless steel, 1-6 parts of molybdenum powder, 1-3 parts of molybdenum disulphide powder, 1-5 parts of rare earth elements, 2-8 part of nickel alloys, 1-9 parts of metallic tin, 1-6 parts of platinum powder and 1-4 parts of chromium powder. According to a manufactured mobile phone metal shell, the impact strength is remarkably improved, the forming processing property is good, the excellent heat aging property and wear-resisting property are achieved, the strength is high, the weight is low, the flame retardant property of a product is excellent, the product is resistant to high temperature, the strength of the product is high, the impact strength is good, the cost is low, operation is easy, and corrosion resistance is achieved.

Description

technical field [0001] The invention relates to a material for a mobile phone case, in particular to an impact-resistant and scratch-resistant mobile phone metal back case, which belongs to the technical field of mobile phone accessories. Background technique [0002] Metal is a shiny, malleable, easily conductive, thermally conductive substance. Most of the metal elements on the earth exist in nature in a compound state. This is because the chemical properties of most metals are relatively active, and only a few metals such as gold and silver exist in a free state. Metals exist widely in nature and are widely used in daily life. They are very important and most widely used substances in modern industry. [0003] Mobile phone cases are mainly made of metal or plastic. Plastic mobile phone casings are cheap, easy to process, easy to color, insulated, and have little impact on signals, and their molding methods are mainly injection molding and pressing, etc., with high prod...
