What Is The Best Marine Grade Aluminum

 Aluminum alloy has been used in the shipbuilding industry for nearly a hundred years. With the rapid development of shipbuilding industry at home and abroad, the lightweight of ships has been paid more and more attention. Due to the low density, high strength, high rigidity and corrosion resistance of aluminum, the ships made of aluminum alloy like AW 5083 h111 are 15-20% lighter than ships built with steel and other synthetic materials.

The high toughness, corrosion resistance and weldability of aluminum alloy provide a good choice for building ships with strict weight requirements. Because aluminum has a lower processing cost, it is more economical to use aluminum to make ships. From the perspective of ship designers, ships made of aluminum alloys can achieve higher speeds and longer service lives.

The aluminum alloys used on ships can be divided into deformed aluminum alloys and cast aluminum alloys. The marine grade aluminum has been used on different kinds ships including all-aluminum marine research ships, ocean-going commercial ships and passenger ships,hydrofoil, hovercraft, passenger ferry, catamaran, transportation boat, landing craft,etc.

Because marine aluminum alloys have special requirements for strength, corrosion resistance, weldability, etc., aluminum-magnesium alloys, aluminum-magnesium-silicon alloys and aluminum-zinc-magnesium alloys are mostly used for shipbuilding.

The marine grade aluminum sheet can be divided into aluminum alloys for ship hull structures and aluminum alloys for outfitting according to their uses. The aluminum alloy used in the hull structure of the ship is mainly 5083, 5086 and 5456, especially Almg4 5mn0 7 h111. The 6000 series alloy is mainly used for the superstructure of the ship because of the intergranular corrosion in the seawater.

The Automotive Aluminum Sheets: 6016 and 6061

 In recent years, Audi and Jaguar Land Rover have used all-aluminum body structures. Aluminum alloy has become an ideal lightweight material. With different alloy compositions and processing, it can be used for car body, frame, clutch housing, brake parts and cover housing, etc.

In addition to gasoline vehicles, lightweight has also become an important issue for new energy vehicles. Aluminum has also become the most cost-effective choice for electric vehicles. The use of automotive aluminum sheets will effectively reduce the body weight of new energy vehicles, thus freeing up more space for power battery.

The use of car aluminum is mainly concentrated in three aspects: automobile wheels, automobile engine gearbox housings,automobile frames, interior trim, bottom plate,etc. The heat treating aluminum 6061 is a common choice for car wheels.

Aluminum alloys for the car body mainly include 2000 series, 5000 series and 6000 series alloy plates. The most stressed part of the car body is made of 2000 series or 7000 series materials, which can be strengthened by heat treatment.

The cover panel is the secondary stress part of the car body, using 5000 series or 6000 series materials. The car door and bottom plate chooses 5xxx or 6xxxx automotive aluminum. The interior part uses 1000 series or 5000 series materials, without heat treatment strengthening. The seat part chooses 2000 series or 6000 series materials are used, which can be strengthened by heat treatment.

6xxx aluminum alloy is a kind of the heat treatment strengthened aluminum alloys, which have higher strength, better plasticity and excellent corrosion resistance. Compared with steel plates, the yield strength and tensile strength of 6000 t4 plates are similar.

Why Is Aluminum Plate Chosen for Fuel Tanker

 With more and more private cars, the use of oil is gradually increasing, leading to the development of the tanker industry. Now most fuel tankers choose aluminum plate such as 5083 aluminum. What can it bring to the fuel tanker? Lets have a look.

1. Low center of gravity design. Under the same cross-sectional area, its center of gravity is reduced by 100mm, and the roll angle is increased to 30 degrees, which is larger than 23 degrees, effectively preventing rollover.

2. The aluminum alloy oil tank truck has a lighter weight due to the use of aluminum plate. By reducing its own weight, the payload of the entire vehicle can be increased. The weight of a single transportation cargo is 18%-35% more than that of a carbon steel tanker.

3. The elongation rate of Haomei 5083 aluminum plate is one times higher than the ordinary aluminum plate which solves the problem of tank body cracking when the ordinary tankers have rear-end collision. The rear suspension can be also designed to be extended by 500mm.

4. The use of Al 5083 h111 on tanker greatly improve maneuverability. Since the center of gravity of the aluminum alloy tanker is relatively low, the braking is easier, which makes the vehicle maneuverability better. The aluminum alloy can also absorb the energy of the collision in the accident through effective deformation, thus improving driving safety.

It is not difficult to find that the use of aluminum alloy tank trucks can not only recover the investment cost in a short time, but also create more economic income and comprehensive benefits than carbon steel tank trucks.

Haomei Aluminum has rich kinds of aluminum plates for fuel tanker, LNG tank and semi truck, including 5083, 5454, 5182, 5754 and 5059 aluminum sheet. Welcome to leave message below to inquire what you need.

The Manufacturing Process of 2mm Aluminum Strip

 The common properties of all rolled aluminum strips are light weight, high strength and good durability. These properties make it widely used in major market areas such as packaging, transportation and construction.

The rolling is one of the main aluminum processing methods, and the raw material is flat ingots. Through hot rolling, a 600mm thick slab can be rolled into a thick plate with a thickness of 6-250mm. The thick plate can continue to be rolled to 2mm to become the raw material for cold rolling. Then it cab slit into 2mm aluminum strip.

Conventional rolling
The aluminum flat ingot is heated to about 525°C, and then reciprocated through the hot rolling mill until the thickness of the aluminum plate reaches the required thickness, or the thickness is small enough (usually 3mm), and then coiled into a coil as a raw material for cold rolling. The last 3-4 passes of hot rolling usually pass through a 3 or 4 sets of rolling mills in sequence.
Through rolling, the metal structure of cast aluminum can be changed to give it new characteristics. Cast aluminum has coarse grains and strong brittleness. Through rolling, its strength and ductility will increase. The strength and ductility of aluminum flat strip are related to the degree of rolling (deformation), rolling temperature, alloy composition and annealing treatment.
Commercial pure aluminum from aluminum smelters contains 99%-99.7% of aluminum, in addition to iron, silicon and other elements. After rolling, aluminum becomes soft and ductile. However, by adding a certain amount of other elements to pure aluminum, such as magnesium, manganese, zinc, copper, and silicon, aluminum alloys can be formed. Different aluminum alloys have completely different properties and strengths.
In addition, through a special refining process, high-purity aluminum with an aluminum content of up to 99.99% can also be obtained. High-purity aluminum is used to produce special products, such as reflector aluminum plates, and aluminum plates used in the electrical industry.
Haomei aluminum flat strip can be used for transformer winding, shutter, gutter, lamp base, etc. As a main aluminum flat strip exporter in China, we have different thickness, width, length and surface treatment. Welcome to leave message below to inquire what you need.
