Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the minimum purity of this aluminum ingot? **A**: The minimum aluminum content is 99.7% by weight, as specified in the reference standard GB/T 1196. This value is a minimum requirement; actual purity may vary by batch and should be confirmed with the supplier. ### Q: What are the typical impurity limits? **A**: The maximum iron content is 0.20 ppm and the maximum silicon content is 0.10 ppm, per GB/T 1196. These limits ensure the ingot is suitable for applications requiring high purity. ### Q: What are the standard dimensions and weight? **A**: The standard dimensions are 600×100×50 mm, and the weight per ingot ranges from 15 to 25 kg. These are typical values; actual dimensions and weights may vary. ### Q: How should the ingots be handled and stored? **A**: Ingots are bundled with steel straps for transport. They should be stored in a dry, clean area to prevent contamination. Always follow the supplier's handling and safety guidelines. ## 6.
