Abstract

The invention belongs to the technical field of magnesium alloy safety helmets, and discloses a magnesium alloy safety helmet, a magnesium alloy material, a preparation method, a preparation system and application. The magnesium alloy safety helmet is applied to safety protection engineering, and is formed by casting an improved magnesium alloy material instead of engineering plastics through a casting grinding tool. The magnesium alloy material comprises the following components in percentage by mass: 65% of Mg, 22% of Al, 3% of Mn and 10% of Zn. The density is low and is one third lighter than that of aluminum, and the specific strength (the ratio of tensile strength to density) is higher than that of aluminum alloy, the fatigue limit is high, larger impact load can be borne compared with aluminum alloy, the thermal conductivity is good, the castability is good, the dimensional stability is good, recovery is easy, cutting machinability is good, vibration reduction performance is good. and the aluminum alloy material is superior to engineering plastic in many aspects and can replace the engineering plastic.

Description

technical field [0001] The invention belongs to the technical field of magnesium alloy safety helmets, and in particular relates to a magnesium alloy safety helmet, a magnesium alloy material, a preparation method, a preparation system and an application. Background technique [0002] Magnesium alloy is an alloy composed of magnesium and other elements. Its characteristics are: low density (about 1.8g / cm3 magnesium alloy), high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, and good corrosion resistance to organic substances and alkalis. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. Magnesium-aluminum alloys are currently the most widely used, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. Mainly used in aviation, aerospace, transportation, chemical industry, rocket and other industrial sector...
