How to ensure the quality of the hardness of aluminum

Aluminum temperature setting and control: In general, the temperature and the table show that the temperature has some errors, set the table when the temperature of the furnace according to the actual temperature setting, and pay close attention to temperature fluctuations. Aluminum heat aging: in strict accordance with requirements of the aging process, the holding time should be appropriate to avoid aging or due to aging and cause hardness is not enough. Blank frame, furnace charging

Aluminum extrusion frame can not be too close to the material and the material at intervals, especially small unventilated materials, thick interval larger pipe materials and small materials together in a single box, pipe materials is conducive to such restrictions air circulation. Furnace before charging 6 XXX will be other special alloys and common 6063 alloy aging furnace installed alone, due to production reasons and oven aging, the aging process take special alloys. Of aluminum extrusion, without limitation low hardness before and not as a product of the use, therefore, in general, have improved strength through aging. Typically, aging can be divided into two kinds of natural aging and artificial aging, the current 6 XXX aluminum production is essentially based on the latter.
