T heat treatment (unlike F, O, H state) after heat treatment of aluminum alloy suitable for floor mats, after (or without) hardening to achieve a stable product. T code must be followed by one or more digits (usually heat-strengthened materials) our common non-heat strengthened aluminum alloy designations are generally behind the letter H plus two figures. T1 is cooled by high-temperature aluminum molding process, then the natural aging to stable condition. For cooling from high temperature after the molding process, no longer cold (can be straightening, flattening, but does not affect the mechanical properties of the limit) products.
