Industrial aluminum profile hardness has an impact on the use, so what to do if the hardness is too low? The aluminum family has passed three quality inspections from raw materials to finished products to ensure the qualified rate of finished products. In the production and processing of industrial aluminum profiles, how to control the hardness is the key. If it is not qualified, it will cause trouble to users.

How to solve the low hardness of industrial aluminum profiles

1. The extrusion frame of aluminum profiles must not be too dense, and there must be a gap between the materials, especially the gap between small materials and thick materials that are not ventilated. , Putting the pipe material below is conducive to aging circulating air supply.

2. Temperature setting and control: Generally, there is a certain error between the temperature and the displayed temperature. When setting the table temperature, set it according to the actual temperature of the furnace, and pay close attention to the temperature fluctuations.

3. Aging of aluminum profiles: Aging must be carried out in strict accordance with the process requirements, and the holding time must be appropriate to prevent insufficient hardness due to under-aging or over-aging.

4. Before the aluminum profile is installed in the furnace, the other special alloys of 6xxx and the ordinary 6063 alloy are separately installed for aging. For production reasons, the aging of the same furnace must be performed with special alloys for aging.
