What's the difference between T5 and T6 of 6063 aluminum?
The 6 series aluminium sheets are Al-Mg-Si alloys, and their representative brands are 6061, 6063 and 6082. Unlike the other series, the state of the 6 series aluminum plates is mainly T-state, and the most is T5 and T6. What is the difference between the two T5 and T6?
Before explaining the difference between aluminum 6063 T5 and T6, users must first understand the following two noun explanations:
Aging: The process of eliminating internal stress in metals.
Quenching: The metal is heated to a certain temperature and suddenly cooled to meet the required hardness. The strength of 2, 6 and 7 series aluminium sheets can be increased by quenching treatment.
T5 means that the temperature of aluminum sheet is rapidly lowered by air cooling after extrusion from the extruder to meet the required hardness requirements (wechsler 8-12 hardness). T6 refers to the instantaneous cooling of aluminum sheet by water cooling after extrusion from the extruder, which makes the aluminium sheet meet higher hardness requirements (wechsler hardness 13.5 or more).
Air-cooled cooling takes a long time, usually 2-3 days, which we call natural aging, while water-cooled cooling takes a short time, which we call artificial aging. The main difference between T5 and T6 states is strength. The strength of T6 state is higher than that of T5 state, and other properties are similar. In terms of price, because of the difference of production process, the price of T6 aluminium sheet is a little higher than that of T5 aluminum sheet per ton
