Analysis of global aluminum product structure

There are certain differences in the global aluminum product structure between different regions and industries, but the following general analysis can be made:

Aluminum materials and semi-finished products: Aluminum materials and semi-finished products are the main components of the global aluminum product structure. This includes aluminum plates, aluminum coils, aluminum profiles, aluminum foil, etc. Aluminum materials and semi-finished products are widely used in construction, transportation, packaging, electricity and other fields, and are the main products of the aluminum industry.

Aluminum building materials: Aluminum building materials are an important part of the global aluminum product structure. Aluminum alloy doors and windows, aluminum curtain walls, etc. are widely used in the construction field. These products are lightweight, corrosion-resistant and durable, providing good architectural appearance and functionality.

Automotive industry: The automotive industry is one of the important areas of global aluminum product consumption. Aluminum alloy parts are widely used in automobile manufacturing, such as engine parts, body structures, wheels, etc. Aluminum's lightweight properties help improve fuel efficiency and reduce tailpipe emissions.

Packaging Industry: Aluminum packaging products have a wide range of applications worldwide. Aluminum cans, aluminum foil, etc. can be used for packaging of food, beverages, pharmaceuticals and other products. Aluminum packaging products have excellent moisture-proof, anti-oxidation and fresh-keeping properties, which can extend the shelf life of products.

Aerospace field: The aerospace field is an industry with a large demand for high-performance aluminum alloys. Aluminum alloys are used in aerospace for aircraft structures, engine parts, aerospace equipment, etc. High strength, light weight and corrosion resistance make aluminum alloys an ideal material choice.

The working principle of extruded aluminum profile mold mainly includes the following steps:

1. Preheating: First, preheat the aluminum profile and extrusion die to a certain temperature.

2. Extrusion: The preheated aluminum profile is put into the extruder and extruded through the cavity of the mold under high pressure to form the desired profile shape.

3. Cooling: The extruded aluminum profile needs to be cooled to fix its shape.

4. Cutting: The cooled aluminum profile is cut to the required length.

5. Heat treatment: In order to improve the hardness and strength of aluminum profiles, heat treatment is usually required.

6. Surface treatment: As needed, the surface of the aluminum profile may need to be frosted, anodized, electrophoretic painted, powder sprayed, etc.

In the whole process, the function of the extrusion die is to determine the shape of the extruded aluminum profile through the shape of its internal cavity during the extrusion process. The design and production of molds directly affect the quality and production efficiency of aluminum profiles.

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.
