H13 steel industrial Aluminium extrusion mold for tube

Advantages of Aluminum Extrusion Dies

1.  The extrusion method can not only produce rods, pipes and other products with simple cross-sectional shapes, but also hollow and solid products with complex cross-sectional shapes.

2. The production flexibility of the extrusion method is very large. Products with different shapes and sizes can be produced only by changing the mold. The mold replacement time is short and the production efficiency is high, which is of great significance for the production scale of small batches.

3. The dimensional accuracy of extruded products is far better than that of rolling and die forging, and the surface roughness is better, so it can be processed without processing and become a finished product.

4.  The mechanical properties of extrusion products are good, especially for aluminum and aluminum alloy products, the extrusion effect is that after quenching or aging, the longitudinal properties of the products are higher than those of rolling and die forging.

5. Compared with rolling, extrusion equipment has compact structure, less land occupation, less infrastructure cost, simple operation and easy maintenance.

6. It is easy to realize semi-automation or automation.

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.

1. 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.

 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.
