Aluminum Perforated Panel Basic State

aluminum perforated panel Basic state

The basic state of the aluminum perforated plate is divided into five kinds, namely, F, O, H, T, W, which represent five kinds of aluminum perforated plate process and stage, different state of aluminum perforated plate, performance and price There will be a big difference. Buy aluminum perforated plate only know grade and I do not know the state, not only may be wrong, but also by businessmen cheated bad. So, what are the meanings of the five states?

  F state

  F state, also known as the free processing state, F state aluminum perforated plate mechanical and chemical properties are not clearly defined, the purchase of F-type aluminum perforated plate customers, the general performance of the aluminum perforated plate has special requirements, after the purchase of their own need for processing Hardening and heat treatment, get the required mechanical and chemical properties.

  O state

  O state, also known as complete annealing state, O state is not subdivided state, on behalf of only after a complete annealing, access to the lowest strength of the aluminum perforated plate products. H state

  H state, also known as processing hardening state, on behalf of the work hardening to improve the strength of the aluminum perforated plate. H state has a lot of subdivision status, such as H18 state, followed by 1 and 8, the first digit represents the processing process: 1 is the work hardening, 2 is incomplete annealing after processing, 3 is low temperature annealing after processing; On behalf of the hardness: 1-8,1 minimum, 8 highest.

  T state

  T-state refers to the heat-treated state of the aluminum perforated plate, indicating that the aluminum perforated plate is stabilized by work hardening. T state has a sub-state, representing a different processing technology, the state from T0 to T10. T state, Tx51 represents the elimination of internal stress, such as T6 state, to eliminate the internal stress, expressed as T651.

  W state

  W state refers to the solution heat treatment state, W state is an unstable state, said aluminum perforated plate after solution treatment, at room temperature in natural aging, W state only that aluminum perforated plate in the natural aging stage.

 H state is a common state of aluminum perforated plate finished products, representing the aluminum perforated plate into the processing hardening treatment, improve the strength. In the five basic states of the aluminum perforated plate (F, O, H, W, T), the H state is one of the most commonly exposed, subdivided states, the same type, the same type of aluminum perforated plate, Subdivision status is different, the performance will be very different.

  The representation of the H state

  H followed by 2-3 digits, said H state subdivision status, 2-digit state of the most common.

  The first digit indicates the machining status of the aluminum perforated plate:

  H1: work hardening state, indicating that the aluminum perforated plate without heat treatment, only by hardening work to obtain the required strength.

  H2: work hardening and incomplete annealing state, said aluminum perforated plate after work hardening, strength exceeds the required requirements, after incomplete annealing, so that the strength of aluminum perforated plate reduced to the standard strength.

  H3: work hardening and stabilization of the state, that aluminum perforated plate after heat treatment or processing in the process of heating, mechanical properties to achieve stability. H3 is only suitable for natural aging aluminum perforated plates at room temperature.

  H4: Work hardening and painting state, indicating that the aluminum perforated plate after processing hardening, the paint treatment and lead to incomplete annealing of the aluminum perforated plate.
