Introduction to global aluminum ore types

Global bauxite deposit types can generally be divided into two major categories: laterite type and sedimentary type.

The ore of laterite bauxite deposits is mainly gibbsite or a mixed type of gibbsite and boehmite. It is characterized by medium aluminum, low silicon, high aluminum to silicon ratio, and high iron. It is a high-quality raw material for the aluminum industry. , easy to harvest and soluble. The reserves of this type of deposit account for about 88% of the world's total aluminum ore reserves. It is the world's main bauxite deposit. It is mainly distributed in the tropical and subtropical ranges between 30° north and south latitude, generally in the offshore plains and mid-low highlands on the edge of the continent. , mesas and islands are visible.

Sedimentary bauxite deposit reserves account for about 11% of the world's total aluminum ore reserves. This type of bauxite deposit presents a variety of ore types due to different ore control times and regions. For example, China's karst bauxite deposits are mainly diaspore type, and the ore characteristics are high aluminum, high silicon, medium Low aluminum to silicon ratio and low iron; karst bauxite deposits in the Mediterranean and Caribbean areas contain both boehmite, gibbsite and various mixed ores. Global sedimentary bauxite deposits are mainly distributed in temperate areas near 30°-60° north latitude.

Aluminum alloy is widely used in door and window accessories, mainly in the following aspects:

1. Aluminum alloy door and window frames: Aluminum alloy has high strength, is not easily deformed, is corrosion-resistant, has good weather resistance, and is easy to maintain. Therefore, it is widely used to make door and window frames, which can not only ensure the stability of doors and windows, but also increase their service life.

2. Sealing strips of aluminum alloy doors and windows: The sealing strips of aluminum alloy doors and windows are generally made of hard aluminum alloy and soft plastic, which can effectively prevent the intrusion of rain and wind dust and ensure indoor temperature and humidity.

3. Pulleys for aluminum alloy doors and windows: The pulleys for aluminum alloy doors and windows are generally made of aluminum alloy and plastic. They are light and wear-resistant and can ensure the smooth opening and closing of doors and windows.

4. Hinges of aluminum alloy doors and windows: The hinges of aluminum alloy doors and windows are generally made of aluminum alloy and stainless steel. They are both strong and corrosion-resistant, and can ensure the stable opening and closing of doors and windows.

5. Decorative strips for aluminum alloy doors and windows: Decorative strips for aluminum alloy doors and windows are generally made of aluminum alloy and plastic. They are both beautiful and durable and can improve the overall aesthetics of doors and windows.

In general, the application of aluminum alloy in door and window accessories can not only improve the performance of doors and windows, but also improve the aesthetics of doors and windows.

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.
