Status of aluminum sheet F
The condition code only indicates that the product is in the natural aging stageT heat treatment status (different from F, O, H state) applicable to heat treatment, after (or without) hardening work to achieve stable products,.T code must be followed by one or more Arabia digital
H is the hardening state, should be followed by a digital representation of what the work hardening and degree of hardness, suitable to improve the strength of the product through the hardening product in hardening after after (or not after) additional heat treatment makes the strength decreased.The status of aluminum sheet is basically divided into five kinds, in addition to the above three kinds, there are two kinds of W and T:W solid fusion heat treatment state, an unstable state, is only applicable to naturally aged alloy at room temperature after solid solution heat treatment.
Status of aluminium plateThe F is free, and the aluminum sheet state is not limited. It is suitable for the products which have no special requirement for the working hardening and the heat treatment conditions in the forming process. The mechanical properties of the products in this state are not specifiedO is an annealed state, that is, a fully soft state, suitable for fully annealed products with minimum strength
