The hardness of industrial aluminum profiles affects their use. So what should be done if the hardness is too low? Aluminum Family ensures the quality of finished products through three quality inspections from raw materials to finished products. Controlling hardness during the production and processing of industrial aluminum profiles is key; any slight non-compliance can cause trouble for users.

How to solve the problem of low hardness in industrial aluminum profiles

1. The aluminum profile extrusion frame should not be too dense; there should be gaps between the materials, especially for small and thick materials that are not ventilated, the gaps should be larger. When combining pipe materials with small materials and plate materials in one frame, placing the pipe materials at the bottom is beneficial for the aging cycle and air circulation.

2. Temperature setting and control: Generally, there is a certain error between the set temperature and the displayed temperature. When setting the temperature, it should be based on the actual temperature of the furnace, and closely monitor the fluctuations in temperature.

3. Aging insulation of aluminum profiles: Aging should be strictly carried out according to process requirements, and the insulation time should be appropriate to prevent under-aging or over-aging, which can lead to insufficient hardness.

4. Before loading aluminum profiles into the furnace, special alloys of 6xxx should be separated from ordinary 6063 alloys for aging. If it is necessary to age them together due to production reasons, the aging process of the special alloys should be used.
