How to control the hardness of industrial aluminum profiles in production and processing is the key, a little unqualified, it will bring trouble to users, so how to solve the hardness of industrial aluminum profiles too low?

　　1. Setting and controlling of the temperature of the aging furnace for aluminum profile: there is a certain error between the temperature of the aging furnace and the apparent temperature of the aging furnace, china recycling copper technology and market and pay close attention to aging furnace temperature fluctuations.

　　2. aluminum aging insulation: in strict accordance with the process requirements to aging, insulation time to be appropriate to prevent under-aging or over-aging and lead to insufficient hardness.

　　3. aluminum extrusion frame can not be too dense, material and material to have a gap, especially not ventilated small material, thick material gap to be larger, pipe and small material, plate together when a box, the pipe is laid down so as to facilitate the aging circulation air supply.

　　4. To Age 6xxx special alloy and 6063 alloy separately before loading, when it is necessary to aging at the same furnace for production reasons, special alloy process should be used to aging.

　　Extruded aluminum profiles, not aging before the low hardness, can not be used as finished products, therefore, in general, must be through aging to improve strength. Generally, aging can be divided into natural aging and artificial aging two kinds, the current 6xxx aluminum profile production is basically the latter-oriented.
