Global aluminum production distribution

Global bauxite output has been relatively stable in recent years, with the combined output of Australia, China, and Guinea accounting for over 72%. From 2020 to 2022, global bauxite output will be stable at around 380 million tons, which is basically stable. The main mining countries of bauxite in the world are Australia, China, and Guinea. Australia ranks first with an annual output of 110 million tons, accounting for 26.3%, followed by China and Guinea, accounting for 23.7% and 22.6% respectively. Production is more concentrated.

Global alumina production is gradually increasing, and China is the country with the largest alumina production in the world. After the growth rate of alumina production peaked in 2017, global alumina production slowed down significantly. In 2022, global alumina production will be 140 million tons, a year-on-year increase of 0.7%, basically the same as the previous year. Among them, China has become the largest alumina producer with a share of 54.3%, Australia and Brazil accounted for 14.3% and 14.3% respectively. 7.9%, the cumulative output of the top three countries accounts for 76.4%, and production is relatively concentrated. Among them, Australia and Brazil are basically self-sufficient in raw materials, while China is highly dependent on the import of raw material bauxite.

Introduction to H13 mold steel

H13 mold steel is a hot work mold steel with good thermal strength and hot hardness, good wear resistance and fatigue resistance, good thermal creep resistance, and high hardness after heat treatment, which can reach HRC46-50. H13 mold steel has stable chemical composition, excellent impact toughness and high toughness, which can ensure the service life of the mold.

H13 die steel is mainly used to manufacture high-strength hot tools, such as hot extrusion dies, hot forging dies, die-casting dies, hot shear blades, etc. In addition, it can also be used to manufacture large plastic molds, cold stamping molds, etc.

The advantage of H13 mold steel is that it has high heat resistance and wear resistance, as well as good oxidation resistance and thermal fatigue resistance, and can maintain good hardness and wear resistance at high temperatures. However, H13 mold steel has poor welding performance and requires special welding processes.

Applications of aluminum alloys in the automotive industry

Aluminum alloys are widely used in the automobile industry and are mainly used in the manufacture of various parts of automobiles, including body, engine, suspension system, rims, etc. Here are some specific applications:

1. Body and frame: The lightweight properties of aluminum alloy make it widely used in the manufacture of body and frame. Using aluminum alloys can significantly reduce the overall weight of a car, thereby improving fuel efficiency and reducing emissions.

2.Engine parts: The high thermal conductivity and excellent corrosion resistance of aluminum alloys make it very popular in the manufacture of engine parts. For example, aluminum alloys can be used to make engine cylinder heads, pistons, and radiators.

4. Rim: The lightweight and beautiful appearance of aluminum alloy make it very popular in the manufacture of rims.

5. Other components: In addition to the above components, aluminum alloys are also used to manufacture other components of automobiles, such as fuel systems, braking systems, electrical systems, etc.

In general, the application of aluminum alloys in the automotive industry can improve the fuel efficiency, performance and durability of the vehicle, while also improving the aesthetics of the vehicle.
