Aluminum is divided into raw aluminum and cooked aluminum. Raw aluminum is less than 98% aluminum, which is relatively brittle and hard, and can only be found by sand casting; cooked aluminum is more than 98% aluminum, which is soft and can be rolled or punched for various utensils. So when ordering extruded aluminum t slot, how to identify whether it is inferior extruded aluminum t slot?
1. The chemical composition is unqualified. The cost of extruded aluminum t slot with a lot of miscellaneous aluminum and waste aluminum doped in the product is greatly reduced, but the chemical composition of the construction extruded aluminum t slot will be unqualified, which will seriously endanger the safety of construction projects.
2. The defective extruded aluminum t slot greatly reduces the closing time, reduces the loss of chemical reagents, and reduces the cost, but the corrosion resistance of the profile is also greatly reduced.
3. The thickness of the oxide film is thin. The national standard rules the thickness of the oxide film of extruded aluminum t slot construction should not be less than 10um (micron). The thickness of the extruded aluminum t slot is not enough, and the surface of the extruded aluminum t slot is easy to rust and corrode. Some extruded aluminum t slots without production name, factory address, production license, and qualification certificate in the random inspection have an oxide film thickness of only 2 to 4um, and some even have no oxide film.
