Az31 Aluminum Magnesium Alloy Rod 32D5 Cast Magnesium Alloy For Medical Parts

Wear - Resistant Non-Toxic Magnesium Alloy Bar For Medical Equipment Structural Parts

Introduction:

The density of pure magnesium is 1.74g/cm3, which is 2/3 of aluminum and 1/4 of steel. Magnesium is the most abundant element on earth, accounting for about 2.35% of the total weight of the earth's crust, second only to aluminum (8.0%) and iron (5.8%) among metal elements. Magnesium compounds are widely distributed in the land, seawater, salt springs and lakes, especially in seawater with extremely high content, 6.4 × 106 tons per cubic mile, and the total content in the ocean is 2.1 × 1015 tons, which can be said to be inexhaustible. , inexhaustible. Magnesium metal can be obtained from magnesium ores such as magnesite, dolomite, carnallite and serpentine, and can also be obtained from natural brines such as seawater and salt lake water or artificial brines. The most commonly used extraction method is the electrode electrolysis method of magnesium chloride molten salt. Magnesium chloride is obtained after smelting, precipitation and chlorination, or directly obtained from brine, and then the metal magnesium is extracted by heating.

Advantages:

• Has good machinability;
• Excellent casting performance, high casting rate, easy to form complex shapes, good appearance and texture, can be used to make notebook computers, cameras and other shells;
• The shrinkage rate of magnesium alloy wire is small, the size is stable, and it is not easy to change due to environmental changes (relative to engineering plastics);
• It has good reprocessing and recycling performance and is known as the green material of the 21st century.

Classification:

According to the classification of processing technology, magnesium alloys can be divided into two categories: cast magnesium alloys and wrought magnesium alloys. There are great differences in composition and tissue properties between the two. Compared with cast magnesium alloys, wrought magnesium alloys have higher strength, better plasticity and more style specifications.

Application:

The automobile industry and the electronics industry have become the industries with the largest demand for magnesium alloys. The use of magnesium alloys in automobiles can reduce the weight by 20% to 25% compared with aluminum alloys. Magnesium alloy extrusions can be used for automotive bearing parts, such as seat frames, window frames, chassis frames, wheel hubs, etc. The thin-walled magnesium alloy extruded pipe fittings are used in automobiles, and due to their small cross-sectional area, they can significantly reduce weight. Magnesium alloy sheets are used in the manufacture of outer panels of automobile body components (such as doors, covers, guards, roof panels, etc.), which can greatly reduce the mass.
