How to Ensure Quality of 5005 Anodized Aluminum Sheet

The anodizing process has been an indispensable processing part for aluminum plates in many fields. 5005 Anodized aluminum sheet has a higher abrasion resistance, corrosion resistance, light resistance and weather resistance. It can be also colored with different colors, making its application value greatly improved.

The aluminum sheet is the main structural materials for doors, windows and curtain walls today. Without surface treatment, the aluminum plate has a single appearance and is easily corroded in a humid atmosphere, making it difficult to meet the high decorative and weather-resistant requirements of building materials.

In order to improve the decorative effect, enhance the corrosion resistance and prolong the service life, the aluminum plate is generally subjected to surface treatment.

The temperature has a significant effect on the performance of the anodic oxide film. If the temperature is too high, the wear resistance and corrosion resistance of the oxide film are reduced, and film formation is difficult; if it is too low, the transparency of the film is reduced, the coloring performance is poor, the brittleness is enhanced, and it is easy to crack.

In the electrolytic coloring production process of anodized aluminum sheet, if we want to achieve uniform coloring and keep the color difference within a certain range to reduce the occurrence of coloring defects, we need to pay attention to the control of the anodizing process.

In addition, the workers should find the cause of poor dying effect in time and properly resolve to ensure product quality. Haomei Aluminum, as a big anodized aluminum sheet suppliers, always deal with the coloring defect in time to ensure it meet the requirements of customers.

The Selection Principle of Marine Grade Aluminum Sheet

The marine grade aluminum sheets have been used in the shipbuilding industry for nearly 100 years. The high toughness, corrosion resistance and weldability of aluminum alloys provide a good choice for ships with strict weight requirements. How to select the right aluminum alloy?

1. High yield strength and elastic modulus

The yield strength and elastic modulus of the material are the most basic parameters for calculating the structural strength of the ship and determining the structural dimensions. The elastic modulus is 70-73 GPa.

Because the elastic modulus and density of various aluminum alloys are almost the same, and adding a small amount of alloying elements or changing the heat treatment state has little effect on them, improving the yield strength within a certain range is beneficial to reduce the weight of the ship structure.

However, high-strength aluminum alloys are generally difficult to have both excellent corrosion resistance and weldability. Therefore, marine grade aluminum alloys for ships are generally selected to have moderate strength and corrosion-resistant weldable aluminum alloys.

2. Excellent welding performance

For ships, the use of welded connections has obvious advantages over the use of riveted connections. The good weldability of the aluminum alloy means that the tendency of the cracks formed by the aluminum alloy during welding is small, that is, the aluminum alloy has good welding crack resistance.

AL-Zn-Mg series and AL-Mg-Si series alloys have significantly reduced strength after welding, and AL-Zn-Mg series alloys have poor corrosion resistance after welding, so these two series are subject to certain restrictions when used as welding marine materials. The AL-Mg alloy has no such disadvantages.

3. Excellent corrosion resistance

Ships are mostly used in harsh seawater and marine environments, so whether aluminum alloys are corrosion-resistant is one of the main signs that determine whether they can be used as marine aluminum alloys.

General requirements for marine aluminum sheet and welded joints in seawater and marine environments are without stress corrosion, spalling corrosion and intergranular corrosion tendency.

4. Good cold and hot forming properties

During the manufacturing process, the ship is subjected to cold processing (such as hemming, roll bending, stamping, etc.) and hot processing (such as hot bending). Therefore, it is required that the marine grade aluminum is easy to process and form, and no defects such as cracks are generated during processing. The performance requirements such as strength and corrosion resistance can still be met after processing.

As a big aluminum sheet manufacturer, Haomei Aluminum has different kinds of aluminum allosy such as 5052, 5083, 5456, 6061, 3003,etc., for shipbuilding. Welcome to inquire marine grade aluminium sheet price from us directly.

3105 Aluminum Coil for Red Wine Caps

It is well known that the red wine is generally packed with wood corks in a very long period.But since the screw caps was successfully developed for win in 1984, more and more wine producers have gradually adopted the screw caps.

At present, the global sales volume of the aluminum cap closure has exceeded 1 billion, and has maintained a rapid growth momentum in recent years. With its own advantages, the sales of aluminum caps will maintain a rapid growth in the following years.

3105 aluminum coil is a main aluminium bottle cap material. 3105 is one of the most widely used anti-rust aluminum with slightly higher strength than that of industrial pure aluminium and 3003 aluminum. What is its advantages of 3105 aluminum coil on wine packaging?

1. Excellent sealing performance

The aluminum bottle cap use a special sealing material for its inner pad. Its low permeability effectively prevent the oxidation of the wine in the bottle, so that the wine maintains freshness and the fruity aroma. No matter how long the storage time is, no chemicals will be produced.

2. Health and environmental protection requirements

During the storage, the red wine may be contaminated with oak because the cork stoppers produce a compound TAC. The gasket of the aluminum pilfer proof caps is the PVDC coating of 0.20 ㎛.which is characterized by stable quality, acid resistance, alcohol resistance and in line with food hygiene packaging standards.

3. Easy to open

The aluminum cap is easy to open and does not require special tools. On the contrary, the cork stopper is difficult to open or even can’t be opened due to breakage. It will be very inconvenient to drink wine in wedding receptions, picnics, aviation wine and other occasions if there is without an opener.

4. Consumer Preference

When consumers were asked how to choose different bottle caps for the same wine, a third of consumers tended to buy wine with aluminum caps, and a quarter of consumers said that the types of caps would not Influence their purchasing decisions. Currently only 30% of consumers will reuse the aluminum caps.

But this move encourages the industry to continue to actively promote the advantage of recycling. In Europe, 40% of aluminum bottle caps will be recycled. As an aluminum bottle cap material manufacturer, we also hope that more aluminum caps will be use to protect our environment.
