1. Aluminum alloys: such as aluminum-magnesium alloys, aluminum-silicon alloys, aluminum-zinc alloys, etc., which have lower density and good strength and corrosion resistance, are widely used in aerospace, automotive, and construction.
2. Steel: mainly a mixture of iron with carbon and other alloying elements (such as molybdenum, chromium, nickel, etc.). With high strength, good toughness and plasticity, widely used in construction, machinery manufacturing, automotive and other industries.
3. Stainless steel: mainly contains iron, chromium and some other alloying elements (such as nickel, molybdenum), has good corrosion resistance, high temperature strength and toughness, applicable to food processing, chemical industry, medical equipment and other fields.
4. Copper alloys: such as brass (an alloy of copper and zinc), bronze (an alloy of copper and tin), with good thermal conductivity, electrical conductivity and corrosion resistance, widely used in the field of electronics, construction, works of art and so on.
5. Magnesium alloys: with low density, high specific strength and good plasticity, widely used in automotive, aerospace and other fields.
6. casting alloys: such as aluminum casting alloys, copper casting alloys, magnesium casting alloys and so on, used in the manufacture of castings and casting products.
In addition to the above alloys, there are many other types of alloys, such as titanium alloys, nickel alloys, zinc alloys, etc., each of which has unique properties and areas of application. There is a wide range of alloys and the exact choice depends on the desired properties and application requirements.
