Pot metal - Wikipedia
Pot metal (or monkey metal) is an alloy of low-melting point metals that manufacturers use to make fast, inexpensive castings. The term "pot metal" came about due to the practice at automobile factories in the early 20th century of gathering up non-ferrous metal scraps from the manufacturing processes and melting them in one pot to form into cast products.

1.1 BACKGROUND OF MAGNESIUM LIGHT ALLOYS
magnesium matrix, and exists in a wide composition range of 48-50 wt% of Al. This intermetallic has a low melting point and poor metallurgical stability, which contribute to poor creep resistance of the alloy at high temperature [25-27]. In 1970s, it was first
Magnesium die casting: frequently asked questions
The alloy is selected based on the environment the part will function in the performance requirements of the component. AZ91D : Most commonly used alloy for high pressure die casting. Offers good strength to weight ratio, very good corrosion resistance and excellent castability.
inorganic chemistry - Why is the melting point of …
High melting point compounds tend to follow the octet rule - the nuer of valence electrons sums to 8. The Group IVB carbides (TiC, ZrC, HfC) have an 8 electron sum (4+4) and have very high melting points - for HfC it is approximately 7100F.
Next-Gen Laptop Materials: Aluminum Alloy vs. …
2017/6/20· Carbon fiber is also much more expensive to produce than even magnesium alloy. The ThinkPad Carbon line uses carbon fiber frames and magnesium body panels. Because of this, it’s being deployed primarily as a coination material, with cases using lightweight and attractive carbon fiber on interior components like the palmrest and touchpad while using alloy metal on the exterior.
The Difference Between Aluminum, Magnesium and Zinc …
2016/4/19· In addition, aluminum does not require as much finishing work as magnesium. Special treatments and coatings are needed when determining a magnesium casting’s appliion. When compared to the cost of melting aluminum, new technology has lowered the expenses required to melt magnesium alloys, but casting requires a higher injection speed.
Magnesium ions are essential to the basic nucleic acid chemistry of life, and thus are essential to all cells of all known living organisms. Plants have an additional use for magnesium in that chlorophylls are magnesium-centered porphyrins.Many enzymes require the presence of magnesium ions for their alytic action, especially enzymes utilizing ATP, or those which use other nucleotides to
Magnesium oxide | Podcast | Chemistry World
This means it takes a lot more energy to pull them apart, so MgO has a melting point of 3125K, nearly three times the melting point of 1074K for sodium chloride. This strong attraction between the ions is also responsible for magnesium oxide being much less soluble than sodium chloride.
