Scope

Scope: This document specifies the naming rules, technical requirements, test methods, marking, packaging, transportation and storage, and test reports for 2xxx aluminum alloy powder materials used in laser selective melting. This document is applicable to 2xxx aluminum alloy powder materials produced by inert gas atomization, plasma rotating electrode, plasma atomization, and plasma spheroidization methods for laser selective melting. Main technical contents: 1. Feedstock: Materials used in the additive manufacturing process. Note: Additive manufacturing processes typically use multiple types of raw materials, such as liquids, powders, suspensions, filaments, and foils. [Source: GB/T 35351-2017, Section 2.5.6] 2. Virgin powder: Powder that has not been used in a batch. [Source: GB/T 35351-2017, Section 2.5.10] 3. Used powder: Powder that has been used at least once during a forming cycle. [Source: GB/T 35351-2017, Section 2.5.11] 4. Powder material: Discrete particle aggregates with sizes below micrometers, formed by certain processing methods. It can be used powder, virgin powder, or a mixture of both. 5. As-built sample: A sample with a certain shape, size, and performance directly obtained after laser selective melting under certain process conditions. Note: The as-built sample has not undergone any post-processing such as sandblasting or heat curing.
