Chicco takes you to understand the main products of aluminum alloy:

Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and it has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing, and the weldability research of aluminum alloy is also in-depth. Aluminum alloy is currently the most used alloy.

1. Aluminum alloy profile

The aluminum and aluminum alloy materials obtained by extrusion processing can be plates, rods and various special-shaped profiles, which can be widely used in new materials in the fields of construction, transportation, transportation, aerospace, etc.

According to the surface treatment method, aluminum alloy plates can be divided into two categories: non-painted products and painted products.

1) Non-painted products　

(1) It can be divided into hammered aluminum plate (irregular pattern), embossed plate (regular pattern) and pre-passivated, anodized aluminum surface treatment plate.

(2) This kind of product does not paint on the surface of the board, does not require high surface appearance, and the price is low.

2) Painted products

(1) Classification:

According to the coating process, it can be divided into: sprayed plate products and pre-rolled plate;

According to the type of paint, it can be divided into: polyester, polyurethane, polyamide, modified silicon, epoxy resin, fluorocarbon, etc.

(2) Among the various coatings, the main performance difference is the resistance to sunlight and ultraviolet rays. The most commonly used coating on the front is fluorocarbon paint (PVDF), which has strong resistance to ultraviolet rays; polyester can be selected on the back Or epoxy resin coating as a protective paint. In addition, a removable protective film can be attached to the front.

2. Aluminum plastic panel

The aluminum-plastic panel is a new type of material made of 3003 aluminum-manganese alloy and 5005 aluminum-magnesium alloy plates with surface treatment and coating baking varnish as the surface, PE plastic as the core layer, and polymer bonding film through a series of processes. It not only retains the main characteristics of the original constituent materials (aluminum alloy plate, non-metallic polyethylene plastic), but also overcomes the shortcomings of the original constituent materials, and thus obtains many excellent material properties. Product characteristics: bright and colorful decoration, weather resistance, corrosion resistance, impact resistance, fire resistance, moisture resistance, sound insulation, heat insulation, shock resistance, light weight, easy processing and forming, easy transportation and installation.

Aluminum-plastic board specifications:

Thickness: 3mm, 4mm, 6mm, 8mm

Width: 1220mm, 1500mm

Length: 1000mm, 2440mm, 3000mm, 6000mm

Standard size of aluminum composite panel: 1220*2440mm

Aluminium composite panel use: It can be used in the decoration of curtain walls, interior and exterior walls, halls, restaurants, shops, meeting rooms, etc., but also in the reconstruction of old buildings, as counters, furniture surfaces, and interior and exterior walls of vehicles.

3. Aluminum veneer

The aluminum veneers are all processed with high-quality aluminum alloys from world-renowned large companies, and then refined by surface spraying of American PPG or Akzo PVDF fluorocarbon baking varnish. The aluminum veneers are mainly composed of panels, reinforcing ribs, and hanging ears.

Aluminum veneer features: lightweight, good rigidity, high strength, non-combustibility, good fire resistance, good processing technology, wide color options, excellent decorative effects, easy recycling, and environmental protection.

Aluminum veneer applications: building curtain walls, column beams, balconies, partitions, interior decoration, advertising signs, vehicles, furniture, booths, instrument shells, subway shipping tools, etc.

5. Aluminum honeycomb perforated sound-absorbing ceiling

The structural structure of the aluminum honeycomb perforated sound-absorbing ceiling panel is a perforated aluminum alloy panel and a perforated back panel. The aluminum honeycomb sandwich structure is directly bonded with the aluminum honeycomb core by high-quality adhesive, and a layer of sound-absorbing cloth is pasted between the honeycomb core, the panel and the back panel. Since the honeycomb core in the honeycomb aluminum plate is divided into numerous closed cells, the air flow is prevented, the sound wave is obstructed, the sound absorption coefficient is improved (up to 0.9), and the strength of the plate itself is improved, so that the size of the single plate can be To be bigger, and to further increase the design freedom. According to the design of the room acoustics, different perforation rates can be designed, and the sound absorption coefficient of the combined structure can be controlled within a certain range, which not only achieves the design effect, but also can reasonably control the cost. By controlling the perforation aperture and distance, the perforation rate can be changed according to the customer's requirements. The maximum perforation rate is less than 30%. The aperture is generally selected as ∮2.0, ∮2.5, ∮3.0 and other specifications. The backplane perforation requirements are the same as those for the front panel. High-quality non-woven fabrics and other sound-absorbing materials. It is suitable for sound-absorbing wall panels and ceiling panels of large public buildings such as subways, theaters, radio stations, television stations, textile mills, and noise-exceeding standard factories and stadiums.

6. Fluorocarbon aluminum plate

6.1) Fluorocarbon spraying plate

(1) Fluorocarbon spraying panels are divided into two-coating system, three-coating system and four-coating system. Generally, a multi-layer coating system should be adopted.

Two coating system: It is composed of 5-10μm fluorocarbon primer and 20-30μm fluorocarbon topcoat. The total thickness of the film should generally not be less than 35μm. Can only be used in normal environments.

Three-coating system: It consists of 5-10μm fluorocarbon primer, 20-30μm fluorocarbon color paint and 10-20μm fluorocarbon varnish. The total thickness of the film should generally not be less than 45μm. It is suitable for severe air pollution, industrial areas and coastal areas and other harsh environments.

Four coating system: There are two types of four coating system. One is to add a 20μm fluorocarbon intermediate paint between the primer and the top coat when using large-particle aluminum pigments; the other is to add a polyamide and polyurethane blend between the primer and the top coat The dense coating improves its corrosion resistance and increases the service life of the fluorocarbon aluminum plate. Because the general fluorocarbon paint has a sponge structure with pores, it cannot prevent positive and negative ions in the air from penetrating to the base of the metal plate. Therefore, this coating system is more suitable for severe air pollution, industrial areas and coastal areas and other harsh environments.

(2) The curing of fluorocarbon baking varnish: it should be baked after a few coats, so that each layer of baking varnish is completely cured, forming good adhesion, corrosion resistance, and fading resistance, avoiding more coating and less baking.

(3) When selecting fluorocarbon paint aluminum panels, attention should be paid to the brand and main technical indicators of fluorocarbon paint, and the fluororesin content should be ≥70%.

6.2) Fluorocarbon pre-rolled coated aluminum plate

(1) The design idea of pre-rolled aluminum sheet is to gather as many material advantages and process advantages as possible in

One body minimizes the quality factors of human influence, and its quality is more guaranteed than fluorocarbon spraying (baking paint) aluminum panels.

(2) The fluorine resin content can reach up to 80%.

(3) The thickness of the coating is generally 25μm.
