Types of Marine Grade Aluminium Sheets

 Aluminum and aluminum alloys are used more and more widely in the shipbuilding industry, ranging from small motorboats to 10,000-ton oil tankers, from offshore hovercraft to submarine . The marine grade aluminium sheet is used to make ship shells, support structures, supporting facilities, pipelines, etc.

The aluminum sheet used in the marine industry can reduce the overall weight of the ship, increase the speed of the ship, and resist the corrosion of the ship by seawater. It is mainly divided into aluminum-copper alloys, aluminum-magnesium alloys and aluminum-silicon alloys.

Aluminum-magnesium alloys are mainly used for hull shells, water pump pipes, pump shells and frame brackets, etc. The grades are 5083, 5086, 5456, 5466, etc. 5083 aluminum plate can be regarded as its typical one. The common tempers are O, H111, H112, H116 and H321,etc. It has medium strength, good corrosion resistance and formability, high fatigue resistance, and is generally used as the main structure of the hull.

7075 aluminium sheet belongs to the Al-Zn-Mg-Cu series. It has good corrosion resistance, good oxidation resistance, good easy processing and wear resistance, and good workability. It has high strength below 150℃, and has particularly good low temperature strength. However, it has poor welding performance, and stress corrosion cracking tendency.

Brushed Aluminum Coil Suppliers

 The brushed aluminum coil is a manufacturing process that repeatedly uses sandpaper to scrape the aluminum coil out of line. The process flow is mainly divided into three parts: deesterification, sand mill, and water washing.

In the brushing process, the special coating technology after anodizing can make the surface of the aluminum coil generate a coating layer containing the metal component, clearly showing each tiny trace, so that the metal matte will appear fine silk luster. The metal shell of many products choose this process to make the product has both fashion and technology elements.

The brushing process is to be done after stamping. The brushed aluminum coil can be made into straight grain, chaotic grain, thread grain, corrugated grain and spiral grain,etc. The straight grain refers to the processing of parallel lines on the surface of aluminum coils by friction with mechanical equipment.

There are two types of straight-grained metal wire drawing: continuous wire and intermittent wire. The continuous wire is obtained by rubbing the surface of the aluminum coil with a wiping cloth or a stainless steel brush based on continuous horizontal parallel lines. Intermittent wire is generally produced in brush milling machines or rubbing machines.

The chaotic grain of the aluminum coil is a kind of irregular and obscure grain obtained moving the aluminum plate up and down, left and right under the high-speed copper wire brush. The corrugated pattern is generally made in a brush milling machine or a rubbing machine. Use the radial exercise of the upper group of grinding rollers to rub the surface of the aluminum coil to get the grain.

The tread grain is to make use of the rotation of the felt and the parallel movement of of the pallet to get an external thread pattern with the same overall width. The spiral grain is mostly used in the production and processing of circular identification plates and small and medium-sized decorative art dashboards.

Aluminum Coil With Kraft Paper

 Aluminum coil with Kraft paper is an kind of aluminum insulation coil which is popular in recent years. It is widely favored in the Middle East countries. The thickness is generally 0.2-2.0mm and the width is between 800-1300 mm. The alloys are 1060,1100, 3003,3004,3104 and 5052 aluminum coil.

There are three processes for the aluminum metal jacket with Polykraft moisture barrier:

1. The Kraft paper is self-adhesive and it is directly pasted on the aluminum coil.

Advantage: This process is of low production cost, high production efficiency and timely delivery.

Disadvantage: The surface of kraft paper is prone to air bubbles due to temperature changes, which affects the bonding effect. The open-air storage time should not be too long. And it is very easy to fall off, thus affecting the quality of construction.

2. The Kraft paper and aluminum roll are bonded together by heating. This process is newly developed by Haomei Aluminum.

Advantage: The adhesion is very high, and the glue will not open or fall off for 24 hours in the water immersion test. The weather resistance is extremely high, and the Kraft paper is not affected by temperature changes.

Disadvantage: The production efficiency is slow and the production cost is too high.

3. The aluminum coil with Kraft paper can be further processed to make embossed aluminum roll and aluminum tile covered with Kraft paper.

During the production of Polykraft laminated aluminum coil, the aluminum coil must be degreasing. The shape must be flat. The weight of each roll can be 2.5 -3 tons or 3.5 tons can be used. The inner hole is made of 505 paper tube core or aluminum core. We adopts the fumigation-free packaging for sea shipping.

What Is PS Plate

 PS plate, the abbreviation of "Presensitized Plate", is a a lithographic printing plate pre-coated with a photosensitive resin layer on the aluminum plate substrate. The high-quality aluminum plate for PS plate is processed by electrolytic grinding and anodizing.

The PS plate features flat coating, uniform thickness, relatively good hydrophilicity, abrasion resistance, and chemical stability, so its printing resistance is very high, which is suitable for printing high, precise and fine products.

The commonly used PS aluminum plate substrate is generally 1050 and 1060 aluminum sheet with H18 temper. In addition to the production of PS plates, 1060 aluminum plate is also widely used in positive PS plates, thermal CTP plates, photosensitive CTP plates, UV-CTP plates, etc.

The width range of Haomei aluminum plate for PS plate making is generally 400-1600mm, and the conventional thickness is 0.10-0.50mm. The aluminum base plate should be of high surface quality and flatness. Therefore, in order to obtain a high-quality alumnum sheet, a special straightening method must be adopted after cold rolling.

With an advanced straightening processing technology, Haomei aluminum plate substrate can avoid such defects like hard scratches, leveling marks, and shock marks. In addition, the electrostatic spraying technology on the matte surface makes the air between the film and the PS plate during printing smoothly drawn out, so that the vacuuming time is shortened by two-thirds compared with the PS plate without the matte surface, thereby reducing the plate making time.

Advanced multi-layer sand mesh technology can help the PS plate base to improve the printing durability. It is composed of sand meshes of different sizes (large waves, medium waves, and small waves). Each size of the sand mesh shares important performance, so as to well realize the balance of printing resistane and stain resistance.
