About This Item
ASTM B945 is the standard practice for aluminum alloy extrusions press cooled from an elevated temperature shaping process for production of T1, T2, T5 and T10-type tempers. It helps define how these extrusions are handled after shaping so the resulting temper condition is controlled and consistent. For manufacturers, buyers, and quality teams, this ASTM standard supports clearer expectations for process control, product consistency, and specification compliance in aluminum extrusion production.
Purpose of ASTM B945
The purpose of ASTM B945 is to provide a recognized practice for press cooling aluminum alloy extrusions after an elevated temperature shaping process when specific temper types are intended. The standard gives technical guidance tied to producing T1, T2, T5, and T10-type tempers, which makes it useful where post-forming cooling history affects final properties. By defining this practice, it helps align processing methods with expected temper outcomes and supports more consistent production results.
Common use cases of ASTM B945
This standard is commonly used in aluminum extrusion production settings where the cooling step after shaping is part of the temper-development process. It is relevant for extruded parts that must meet defined temper conditions for downstream fabrication, assembly, or performance requirements. ASTM B945 may also be referenced in procurement documents, production specifications, and quality procedures when a controlled press-cooled process is needed to support the required T-type temper designation.
Why ASTM B945 matters
ASTM B945 matters because cooling practice can influence whether an aluminum extrusion achieves the intended temper condition consistently. Using a recognized ASTM standard helps reduce ambiguity in manufacturing instructions, inspection expectations, and supplier communication. It can also support quality control by giving a shared reference for process handling and product evaluation. For organizations that specify or produce aluminum extrusions, ASTM B945 helps improve consistency and lower the risk of temper-related nonconformance.
