What is the hardness of general industrial aluminum?

Hardness determines the quality of industrial aluminum profile, so companies should control the hardness during the production process to improve the availability of its performance. How should the hardness of industrial aluminum profile be controlled? The specific methods are as follows: 1. Temperature setting and control: In general, there is a certain error between the actual temperature and the temperature displayed by the meter. The furnace setting the meter as the temperature is set according to the actual temperature and pay close attention to temperature fluctuations. Aluminum aging and heat preservation: It is not enough to strictly follow the process requirements for aging, and the heat preservation time should be appropriate to avoid under-ageing or aging and resulting in hardness. 2. The aluminum profile extrusion frame should not be too close, the material and the material are separated, especially the small material that is not ventilated, the thicker spacing is larger, the pipe material and the small material, single together in a box, the pipe material has such a Conducive to restrict air circulation. 6 XXX before the aluminum furnace is charged, other special alloys and common 6063 alloys are separately loaded into the furnace for aging. Due to production reasons and furnace aging, the special alloy process is adopted for aging. The aluminum produced by extrusion, without limitation of low hardness, is not used as a finished product, therefore, generally speaking, the strength must be improved through aging. Generally, aging can be divided into natural aging and artificial aging. At present, the production of 6 XXX aluminum profiles is essentially the latter. Since we are making stainless steel and titanium alloys, as far as I know, the hardness should also be related to the material. There are also many kinds of materials in the category of aluminum, and each hardness is definitely different. ————The article comes from the Internet.
