October 16, 2018

1050 ho temper aluminum circle plate is representative of 1000 series of aluminum discs. H and O are two common series of tempers for aluminum circle plates. O refers to the soft state of the plate without cold hardening which means to improve aluminum circle plate’s hardness by special processes. For example, H1 means the hardness obtained by pure cold hardening, and H2 means that the plate has gone through a further process of incomplete annealing, because its hardness after cold hardening surpasses that required, while H3 refers to the hardness after both processes of cold hardening and stabilizing treatment. Therefore, H state may stand for H1, H2, H3 to H112. The second number after H represents the circle’s hardness degree, which weakens successively from 9 to 1. The third number refers to special treatment of the plate’s surface or shape, like coating, extrusion, embossing etc.

The problem with both is their being invulnerable to corrosion. Aluminum, however, is endowed with extraordinary corrosion resistance, and even though it gets “rusty”, it does no harm to human health. Modern technology and manufacturing process further help improve its corrosion resistance. What’s more, aluminum cookwares are much lighter, which is really important since they are usually held around the kitchen.
