Non-ferrous metals are divided into basic metals and minor metals. Niche metals are relatively Niche in units, so they are called Niche metals. The types of Niche metals are: Magnesium ingots and antimony ingots; electrolytic manganese; cadmium ingots and bars; electrolytic cobalt; refined bismuth; chromium; sponge titanium; sponge zirconium; metal silicon; indium; calcium; tungsten bars; selenium ingots; potassium; sodium; niobium; vanadium; hafnium; Gallium; Beryllium; Molybdenum; Metallic lithium; Tellurium; Germanium ingot; Rhenium; Metallic arsenic. According to the draft plan of the "Twelfth Five-Year Plan" for my country's non-ferrous metals industry, by 2015, the output of ten non-ferrous metals (copper, aluminum, lead, zinc, nickel, tin, antimony, magnesium. sponge titanium, mercury) will be controlled within 41 million tons. This move will push up the price of rare Niche metals. Indium: my country's reserves rank first in the world. Account for 80% of global supply. Mainly used in the manufacture of flat panel displays, alloys, semiconductor data transmission, and aerospace products. It is mainly associated with lead-zinc mines. In 2005, my country's primary indium output was only 410 tons. Indium is an associated metal, but the content of zinc concentrate is calculated in PPM (millions), which is very Niche and cannot be regenerated. Tungsten: my country has the largest reserves in the world. It is the metal with the highest melting point, with a melting point of 3410°C. It accounts for 85% of global supply. It is mainly used in cemented carbide, special steel and other products, and is widely used in the defense industry, aerospace, and information industry, and is called the "industrial teeth". If a country does not have tungsten, there will be a great lack of metal processing capacity under technical conditions, which will directly lead to the paralysis of the machinery industry, so it is called strategic metal. In addition, tungsten must be used as the filament in the lighting field. Molybdenum: my country's reserves rank second in the world. It accounts for 24% of global supply. It is used to make various alloy steels, stainless steels, heat-resistant steels, and super alloys. It is widely used in the military industry and is called "war metal". Rare earth: my country's reserves rank first in the world. Supply accounts for more than 80% of the global total. Used to make composite materials, alloy materials such as magnesium, aluminum, and titanium are vividly compared to "industrial MSG." Germanium: The reserves rank first in the world. Production accounts for 50% of the world. It is mainly used in the production of night vision devices, thermal imagers, petroleum products catalysts, solar cells, etc., and is widely used in the field of optical fiber communication. Titanium: Titanium and titanium alloys are widely used in the aviation industry and are called "space metals"; in addition, they are increasingly widely used in the shipbuilding industry, chemical industry, manufacturing mechanical parts, telecommunications equipment, and cemented carbide. In addition, because titanium alloy has good compatibility with human body, titanium alloy can also be used as artificial bone. Vanadium: melting point 3380°C. Vanadium is used in steel because it can form a stable carbon compound (V4C3) with the carbon element in steel. It can refine the structure and grains of steel and increase the temperature of grains. Significantly improve the performance of steel. It can increase the strength, toughness, corrosion resistance, wear resistance and impact load ability of steel.
