To learn casting technology, please log on to the casting order website.

7000 series aluminum bars belong to aviation series, which are Al-Mg-Zn-Cu alloy, heat treatable alloy and superhard aluminum alloy with good wear resistance.

The melting and casting of aluminum bars include melting, purification, impurity removal, degassing, slag removal and casting. The main process is:

1, batching: according to the specific alloy brand to be produced, calculate the addition amount of various alloy components and reasonably match various raw materials.

2. Melting: The prepared raw materials are added into a melting furnace for melting according to the process requirements, and impurities and gases in the melt are effectively removed through degassing and slag removal refining.

3. Casting: Under certain casting process conditions, molten aluminum is cooled and cast into round cast bars of various specifications by deep well casting system.

Aluminum bar type:

And all kinds of aluminum bars. Generally speaking, according to the aluminum content of aluminum bars, there are the following kinds of aluminum bars, and the characteristics and application fields of different types of aluminum bars are also different.
