Production Process

Magnesium Alloy Tube is produced by process semi-casting and extruded process.

Semi-casting is through using vertical casting and is colded by constant temperature well water under around during casting processing. Making casting completedly slabs(billets) have very small grain and very tight spacing between grain and grain.

Ensuring perfect inner quality without pore and slag inclusion.Which can be verified that we used Inspection method for macrostructure of wrought magnesium alloy products.

We produce magnesium alloy sheet conforms to MIL-T-38749(USAF) Standard.

Normal mention to Magnesium Alloy Sheet is pointed magnesium alloy hot rolling plate which is through heating treament state H24, H26,O.

So AZ31B H24 magnesium alloy sheet has a perfect flatness and good surface with moderate strength and ductility.

Mg is an basic material in the magnesium aluminum alloy industry, die casting industry, widely used as desulfurization in hot steel and iron pretreatment , welding materials , and fireworks etc;

Magnesium is also used to make photographic and optical instruments,. Magnesium and its alloys of non-structural applications, magnesium as a strong reduction agent, also used for titanium, zirconium, beryllium, hafnium production.

Features:

As the lightest metal material, magnesium alloy has the advantages of better capability of shock absorption, easy to be grind, electromagnetism interference screening etc.

Can be used as equipment parts,3C products , etc.

Magnesium Alloy functions

1.high mechanical stability

2.high damping capacity

3.low internal stresses and distortions

4.good heat conductivity

5. good machining properties
