【China Aluminum Network】 T5 and T6 are all types of heat treatment.

T5 is aluminum extrusion from the extruder after cooling with air cooling aluminum to achieve the required hardness (Webster 8 - 12 hardness).

T6 is aluminum extrusion from the extruder after water cooling aluminum temperature, aluminum profiles to achieve higher hardness requirements (Webster 13.5 or more hardness) T5 quenching in the profile plant is generally used air-cooled, T6 in The quenching of the profile plant is generally water-cooled. Both have the same elastic modulus. Under normal circumstances, with the T5 state, if the deflection of the rod passes and the tensile strength is slightly worse, the T6 state can be used. The strength of T6 is better than T5, but T6 is generally higher than T5 by 500-1000 yuan. T5 is usually air-cooled when quenched in a profile plant. T6 is generally water-cooled when quenched in a profile plant. Both have the same elastic modulus. Under normal circumstances, with the T5 state, if the deflection of the rod passes and the tensile strength is slightly worse, the T6 state can be used. The strength of T6 is better than T5, but T6 is generally higher than T5 by 500-1000 yuan.

In addition, T5 is generally used for air-cooling at the quenching of a profile plant. T6 is generally water-cooled at the quenching of a profile plant. Both have the same elastic modulus. Under normal circumstances, with the T5 state, if the deflection of the rod passes and the tensile strength is slightly worse, the T6 state can be used. The strength of T6 is better than T5, but T6 is generally higher than T5 by 500-1000 yuan.
