Magnesium Alloy Welding Wire Az31 Az61 Az91 Chinese Supplier
Introduction:
ER AZ61A The weldability of most magnesium alloys is good when proper filler metal in employed. A filler metal with a lower melting point and a wider freezing range than the base metal will provide good weldability and minimize weld cracking. AZ61A or AZ92A filler metals may be used to weld base metals of similar composition and also ZK21A base metal.
AZ61A filler metal is generally preferred for welding wrought base metals of those alloys because of lower cracking tendency. However, welds made in cast Mg-Al-Zn and AM100A base metals with AZ92A filler metal show less crack sensitivity. The weld metal will respond to the precipitation heat treatments normally applied to repaired castings. AZ101A filler metal may also be used to weld those cast base metals. EZ33A filler metal is used to weld wrought and cast base metals designed for elevated-temperature service; however, this filler metal should not be used for welding aluminum-bearing magnesium alloys because of severe weld cracking problems. When no other filler metal is available, most base metals may be welded with strips cut from the base metal.

Use
Electrochemical Applications.
Magnesium is used as an alloying element in nonferrous alloys. Such as aluminum.zinc, and lead. It is used as an oxygen scavenger in nickle and copper alloys and a desulfurizer in iron and steel production. Magnesium improves the toughness and ductility of cast iron by making the graphite particles nodular. This is the greatest use of magnesium by weight.
Medical Applications:
Magnesium alloys are used in portable medical equipment where light weight is advantages. It is also employed for wheelchairs used in sporting activities(where every ounce is critical). Because of magnesium’s biocompatibility and bioabsorbability, alloys with other biocompatible elements(such as calcium) are being evaluated for cardiovascular stents and orthopedic devices for internal bone fixation.
Structural:
1. Automotive Industry:
Clutch and brake pedal support brackets.
Steering column lock housing:
Manual transmission housing.
2. Industrial Machinery:
Textile and printing machines. Magnesium alloys are used for parts that operate at high speed but must be lightweight to minimize inertial forces.
3. Material Handling equipment:
Dockboards, grain shovels, gravity conveyors.
4. Commercial applications:
Handheld tools, Luggage, computer housing, ladders.
5. Aerospace:
Magnesium Alloys are valuable for aerospace application because they are lightweight and exhibit good strength and
stiffness at both room and elevated temperatures
6. Bicycle:
Magnesium Alloys are used in the bicycle industry due to its excellent stiffness and reduced weight compared to Aluminum.
