Of these four alloys, titanium alloy is the hardest and the strongest. In terms of hardness, titanium alloys are far harder than the other three alloys. In terms of tensile strength, titanium alloys are stronger than zinc alloys, followed by magnesium alloys, and aluminum alloys are the weakest.<\/p>\n\n\n\n

However, in terms of product structure design, weight also needs to be considered. If the specific gravity is considered in terms of progress, zinc alloy has the smallest specific strength because of its highest density. Titanium alloys and magnesium alloys have high specific strength, but titanium alloys are expensive and have poor processability. Therefore, magnesium alloys are mostly used in structural parts that take weight and strength into account.<\/p>\n\n\n\n

Magnesium and magnesium alloy<\/h3>\n\n\n\n

Magnesium has low density and is easy to burn due to its physical and chemical properties. At 20\u00b0C, the density of metallic magnesium is 1.738g\/cm3, and the density of liquid metallic magnesium is 1.58g\/cm3; under standard atmospheric pressure, the melting point of metallic magnesium is (650\u00b11)\u00b0C, and the boiling point is 1090\u00b0C. When heated in air, metallic magnesium begins to burn at 632\u00b0C to 635\u00b0C. Therefore, it is determined that the preparation and alloy smelting process of magnesium are relatively complicated. The purity of magnesium for industrial use can reach 99.9%, but pure magnesium cannot be used as a structural material. Magnesium alloys formed by adding elements such as aluminum, zinc, lithium, manganese, zirconium and rare earth to pure magnesium have high strength. Currently, the most used Magnesium-aluminum alloys are 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 sectors.<\/p>\n\n\n\n
