Magnesium Ingots

Product Description

Magnesium ingots are standardized based on their purity levels, chemical composition, and physical dimensions to ensure they meet the needs of industries like aerospace, automotive, and electronics.
1. Purity Grades & Chemical Composition
The most common standard for unalloyed magnesium is ASTM B*2/B*2M. Purity typically ranges from *9.8% to *9.***9% (6N).

| Grade | Mg Content (Min) | Max Impurities (Typical) |
|**-|**-|**-|
| Mg*9.*9% (4N) | *9.*9% | Fe < 2ppm, Cu < 2ppm, Ni < 6ppm |
| Mg*9.*5% | *9.*5% | Fe ≤ 0.**4%, Si ≤ 0.**5%, Al ≤ 0.**6% |
| Mg*9.*0% (3N) | *9.*0% | Fe ≤ 0.*4%, Si ≤ 0.*1%, Al ≤ 0.*2% |
| Mg*9.*0% | *9.*0% | Fe ≤ 0.*5%, Si ≤ 0.*3%, Al ≤ 0.*5% |

2. Common Alloy Specifications
For structural use, magnesium is often alloyed under the ASTM B*3/B*3M standard.

* AZ*1D: Contains ~9% Aluminum and 1% Zinc; used for high-pressure die casting.
* AM*0B: Contains ~6% Aluminum and 0.3% Manganese; known for high impact strength.
* WE*3: Contains Yttrium and Rare Earths; designed for high-temperature aerospace applications.

3. Physical Dimensions & Weight
Ingots are produced in various sizes to fit different furnace capacities.

* Small Ingots: ~**0g to 1 kg for specialized or lab use.
* Standard Industrial Ingots: Typically 7.5 kg or *5 kg (+/- 0.5 kg).
* Large Blocks/Slabs: Can range from *0 kg up to *0 kg for mass production.
* Typical Size (Small): Nominally **3 cm x **8 cm x ***2 cm.
* Typical Size (Standard): Approximately ****5 cm x *1.***3.5 cm x **7.5 cm.

4. Technical Properties (Theoretical)

* Density: ~1.**8 g/cm³ (roughly 2/3 the weight of aluminum).
* Melting Point: ~**0°C (***2°F).
* Boiling Point: ~***0°C.
* Thermal Conductivity: **6 W/m·K
