How to Identify the Quality of Aluminum

In the vast field of aluminum alloys, we often encounter various aluminum alloy materials. These materials play a vital role in the industrial field. Whether it is aviation, aerospace, or automobile, machinery manufacturing, shipbuilding and chemical industry, aluminum alloys are indispensable. With the rapid development of the technological era, the demand for aluminum alloys is growing, and related research is becoming more and more in-depth. However, faced with a wide range of aluminum alloy models, many of which have similarities, how can we accurately distinguish them?

Alloying elements: 6063 aluminum alloy is an alloy prepared with aluminum, magnesium and silicon as the main elements. Each element has a certain range of content, and the price of magnesium is high. In order to reduce costs, some manufacturers reduce the amount of magnesium to the minimum allowable content. Even worse, the magnesium content is lower than the minimum allowable content. Some factories add waste wires and waste aluminum pots to the alloy, basically not talking about 6063 alloy. As a result, the mechanical strength of the aluminum profile is very low, it can be so low that it can be easily bent with both hands, and it is commonly known as soft as "noodles". This is one of the reasons why industrial aluminum can be thousands of dollars cheaper.

Regular aluminum profile manufacturers have internal standards when formulating alloy components, that is, within the range of various element content, each plant has its own smaller range of changes, and the ratio of aluminum, magnesium, and silicon is very strict. Each factory has its own data and keeps each other confidential. Only the alloy made with qualified formula can guarantee the quality, otherwise the quality will not be improved on how to process it in the future.

In addition, the chemical composition and smelting process of aluminum alloys have a profound impact on their properties and characteristics. Different types of aluminum alloys have different application areas in the market. Therefore, when purchasing and using aluminum alloys, it is necessary to carefully distinguish their types and properties to ensure correct selection and application and avoid potential problems.
