What do the 6063 and T5 represent in the aluminum profile 6063-T5?
third, and four digits:Pure aluminum: represents the original alloyAlloy: the designation of individual alloys"- >: the back of Hn or Tn indicates the condition of work hardening or the symbol of heat treatment state-Hn: indicating the symbol for non heat treated alloys-Tn: a symbol for heat treatment alloysT5By cooling the high temperature molding process, and then the artificial aging state. Applied by cooling high temperature molding process, not through the cold processing (for straightening and leveling, but does not affect the mechanical properties of the limit), to artificial aging products.
5: the main alloying element is magnesium6: mainly add alloy elements for silicon and magnesium7: the main alloying elements are zinc and magnesium8: a new alloy that does not belong to the above alloy series2.2, second digits: an alloy that indicates the addition of alloying elements or impurities in the original alloy0: table alloy1: table original alloy by the first amendment2: table original alloy after second modifications2.3,
Alloy number: our country's current general is the American Aluminum Association "Aluminium Association" numberExamples are as follows: 1070-H14 (pure aluminum)2017-T4 (heat treatment alloy)3004-H32 (non heat treated alloy)2.1 first digit: indicates the main addition of alloying elements1: pure aluminum2: the main alloy element added copper3: the main alloying elements are manganese or manganese and magnesium4: the main alloy element is added silicon
