For aluminum aluminum alloy products, aluminum die casting is used, the quality of aluminum die casting determines the quality of aluminum alloy parts. Therefore, the processing quality of aluminum die casting is particularly concerned. For this, there are also very strict standards in the industry to test the chemical composition, mechanical properties other aspects of aluminum die casting processing.

1. Chemical composition

The inspection method, inspection rules re inspection of chemical composition of aluminum alloy shall conform to the provisions of GB / t15115; samples of chemical composition can also be self casting, but must conform to the provisions of GB / t15115.

2. Mechanical properties

The inspection method, frequency rules of mechanical properties shall comply with the provisions of GB / t15115. When the die casting body is used as the sample, the size test form of the cut part shall be determined by the supplier the demander.

3. The geometric dimension of the die casting can be inspected according to the batch sampling inspection GB2828 gb2829, the inspection results shall conform to the provisions of 3.3 of this standard.

4. The factory inspection of die casting surface quality shall be carried out one by one, the inspection results shall conform to the provisions of this standard.

5. The surface roughness of die casting shall be in accordance with the provisions of GB / t6060.1.

6. The surface of the die casting to be polished shall be in accordance with the provisions of GB / T 6060.4.

7. The surface of die casting to be shot peened sand blasted shall be in accordance with the provisions of GB / T 6060.5.

8. The test methods inspection rules for the internal quality of die casting can include: X-ray photos, NDT tests, metallographic photos die casting profiles, etc. the inspection results shall conform to the provisions of 3.4.6 of this standard.

9. Other test methods inspection rules shall be in accordance with the provisions of GB / t15114.
