When many customers choose industrial aluminum profiles, they are often confused by obscure aluminum alloy grades. For a simple example, what does T5 in aluminum profile 6063-t5 mean? This question has plagued many customers who are new to aluminum profiles. , Let’s explain in a short answer below.

1. 6063 of the aluminum profile 6063-T5 is the grade of the aluminum alloy. The 6063 aluminum alloy is a medium-strength heat-treatable alloy in the AL-Mg-Si series, which belongs to the sixth series of aluminum alloys.

  2. T5 in aluminum profile 6063-T5 is the classification mark of heat treatment. The first digit after T indicates the basic type of heat treatment (from 1 to 10). T5 means artificial aging after cooling from the forming temperature.

  Aluminum alloy grade description: my country's current common use is the number of the Aluminum Association of the United States.

   The first digit: indicates that the main alloying elements are added. 1: Pure aluminum 2: The main added alloying element is copper 3: The main added alloying element is manganese or manganese and magnesium 4: The main added alloying element is silicon 5: The main added alloying element is magnesium 6: The main added alloying element is silicon and magnesium 7: The main added alloying elements are zinc and magnesium. 8: A new alloy that does not belong to the alloy series listed above

   The second digit: It means the alloy with the content of the main added alloying element or the content of the impurity component in the original alloy has been modified. 0: Table original alloy 1: Table original alloy was modified for the first time 2: Table original alloy was modified for the second time

The third and fourth digits: Pure aluminum: indicates the original alloy: indicates the code of the individual alloy "-": the following Hn or Tn indicates the state of work hardening or the chain degree symbol of the heat treatment state-Hn: indicates the chain of the non-heat treated alloy Degree symbol

  -Tn: represents the chain degree symbol of heat-treated alloy
