An aluminum-zinc-tin alloy called KA90 is commonly used in marine and water heater applications. [9] Zinc and aluminium are generally used in salt water, where the resistivity is generally lower and magnesium dissolves relatively quickly by reaction with water under hydrogen evolution (self-corrosion).
InGaN/GaN nanorod array light-emitting diodes can be manufactured with dry etching or focused ion beam etching techniques. [6] Such LEDs emit polarized blue or green light [7] Three-dimensional nanorod structures have a larger emitting surface, which results in better efficiency and light emission compared to planar LEDs. [8]
In 2019, 552,400 tonnes of zinc, 71 percent of US mined zinc production, and 4.2 percent of world zinc production, came from Teck Resources' Red Dog mine, the world's most productive zinc mine, in northwest Alaska, near Kotzebue. [2] [3] [1] The mine opened in 1989. [4] The zinc is shipped as concentrate to foreign smelters.

The two most prevalent shape-memory alloys are copper-aluminium-nickel and nickel-titanium (), but SMAs can also be created by alloying zinc, copper, gold and iron.Although iron-based and copper-based SMAs, such as Fe-Mn-Si, Cu-Zn-Al and Cu-Al-Ni, are commercially available and cheaper than NiTi, NiTi-based SMAs are preferable for most applications due to their stability and practicability [1 ...
