3 Technical requirements

3.1 Grade The products are divided into 10 grades according to the matrix and particle content. The grade is determined by the product name (expressed by FCA, F for powder, CA for granule Grain-reinforced aluminum matrix composite materials), matrix grades (such as aluminum alloy matrix modified in the original grade, distinguished by X, Y, where X represents The base silicon content is 6.50%~7.50%, the magnesium content is 0.90%~1.50%; Y represents the base silicon content is 9.00%~11.00%, and the magnesium content The amount is 0.20%~0.45%), particle content composition. Example 1. The aluminum alloy powder of modified cast aluminum alloy ZL101 reinforced with 2% mass fraction of titanium boride particles is marked as. FCA101X-2. Example 2. The aluminum alloy powder of the deformed aluminum alloy 7075 reinforced with 6% titanium boride particles is marked as. FCA7075-6. 3.2 Chemical composition The chemical composition of the product should meet the requirements of Table 1.When the buyer has special requirements for the matrix and particle content, it shall be determined by the supplier and the buyer through consultation. And indicate in the order form (or contract). ......
