Extrusion Plate Az91 Magnesium Alloy Sheet OEM For Aerospace

Easy To Form Complex Shapes Magnesium Alloy Sheet For Aerospace Industry

Introduction:

Magnesium alloys are alloys based on magnesium and other elements. Its characteristics are: low density (about 1.8g/cm3), high strength, large elastic modulus, good heat dissipation, good shock absorption, larger 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 alloy has the characteristics of low density, high specific strength and specific stiffness, good dimensional stability, good thermal conductivity and electrical conductivity, vibration absorption and easy processing and forming, so magnesium alloy is one of the competitive lightweight materials.

Classification:

Magnesium alloys are generally classified in three ways: chemical composition, forming process and whether they contain modifier zirconium or not.

According to chemical composition, based on five main alloying elements Mn, Al, Zn, Zr and rare earth, the alloy system is composed: Mg-Mn, Mg-AL-Mn, Mg-Al-Zn-Mn, Mg-Zr, Mg- Zn-Zr, Mg-Re-Zr, Mg-Ag-Re-Zr, Mg-Y-Re-Zr.

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

Zirconium has a strong grain refining effect on magnesium alloys. According to whether magnesium alloys contain zirconium, they are divided into two categories: zirconium-free magnesium alloys and zirconium-containing magnesium alloys.

Features:

Lightweight magnesium alloys compared with commercial aluminum alloys/steels
Low cost because of room-temperature forming process and inexpensive alloying elements
Excellent combination of mechanical properties and formability surpassing those of the existing magnesium sheet alloys and comparable to aluminum alloys.

Application:

• Automotive: structural and closure panels; interior and chassis components
• Aerospace: seats, luggage rails, and sheet components
• Electronics: casing, housing, chassis, frames
