AZ91 Wrought Magnesium Alloy Aluminum Magnesium Alloy Higher Strength

High Specific Strength Wrought Magnesium Alloy For Automobile Industries

Introduction:

Wrought magnesium alloy has greater development potential than cast magnesium alloy. Through the control of material structure and the application of heat treatment process, wrought magnesium alloy can obtain higher strength, better ductility and more diverse mechanics performance, so as to meet the application needs of diverse engineering structural parts. Wrought magnesium alloys are often heated to a certain temperature and processed by hot forming techniques such as extrusion, rolling and forging.

Features:

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.

Application:

High-performance magnesium alloys are excellent aerospace materials. For example, the magnesium alloy (AZ31) matrix composite material with silicon carbide whiskers (20% by volume) as the strengthening phase, its elastic modulus is increased by 10%, and the strength is increased to about 450MPa; the United States has used magnesium alloy composite materials to manufacture propellers, For missile tails, etc., naval satellites have used magnesium alloy composite materials for structural parts such as brackets, bushings, and beams, and their comprehensive performance is better than that of aluminum-based composite materials.
