The Method of Good Or Bad Aluminum and How to Choose Aluminum Profiles-WJW Aluminum Supplier Aluminum

Generally, the real aluminum surface should be affixed with the protective film of the WJW logo, a pearl cotton or a bubble film, and a packaging paper. It is firm and true to check the tag bar code on the sealed head with WJW. , Packaging count, single -tile weight and profile section drawings.

Method of the quality of aluminum.

1. When selecting, see the factory date and specification model of aluminum materials, as well as the product name and the corresponding production license number, and see how the surface color of the aluminum material is used to see if the gloss is better. And there are obvious defects on the surface. If there is any circumstances, it is better to replace the relatively complete aluminum materials for purchases, and the thickness of the aluminum material cannot be lower than 1 mm, and the thickness of the membrane thickness cannot be less than 10um. The thickness of the coating cannot be greater than 40 120um, aluminum.

2. When choosing aluminum, it is better to choose products with better corrosion performance. In this way, when used, the performance is relatively strong, and the surface of the aluminum material cannot be used. This will cause the surface of the aluminum material to be damaged and can be wiped with water and soap.

3. After the aluminum is squeezed, there will be some defects. If the squeezing process is not particularly mature, this phenomenon will occur, and the thickness of the oxide film is particularly thin, basically about 10um, it will basically be around 10um or so , And during random inspection, be sure to check the surface of the aluminum material, whether there are production licenses and qualification certificates, as well as the address of the factory, and so on.

my country's architectural aluminum products started in the early 1980s. The rapid development speed was the world's first place. From aluminum profiles, aluminum doors and windows, aluminum curtain walls to hidden frame aluminum glass curtain walls, only a little more than ten years. Reasons: Introduce the production line of aluminum and aluminum doors and windows in more than a dozen countries abroad, and the director of various countries, and insisting on digestion and absorption is one of the important reasons.

Due to excessive development, there are also many problems: for example, the manufacturers of building aluminum materials have increased rapidly, and the production volume is too large. The manufacturer with a production capacity of half of the design is very good, and the competition for aluminum sales is fierce.

How to choose many aluminum profiles in China, due to the different conditions, the material produced is very different, and the sales price is also large. In the process of processing, there is such a large price difference, and the quality difference is definitely very different.

The regular aluminum manufacturers have internal standards when preparing the alloy ingredients, that is, within the range of various element content, each factory has their own smaller changes. Each factory has its own data, keeps confidential, and has a qualified formula to ensure the quality. Otherwise, how to process it in the future, the quality will not go up.

The level of domestic casting equipment in alloy casting is also far from the same difference. The older casting equipment in China has iron model casting in the 1940s. The advanced semi -continuous casting of hydraulic pressure. There are a lot of residue and bubbles. The quality of the casting rod is very poor. Now it is generally commonly used in factories. Horizontal casting (also known as continuous casting) and semi -continuous casting. Aluminum.
