What are the quality control points for purchasing 6061 aluminum alloy forgings?

When purchasing 6061 aluminum alloy forgings, the following are the main points of quality control:

Specification requirements: Ensure that the specification requirements of 6061 aluminum alloy forgings are clear with the supplier, including size, shape, material, hardness, chemical composition, etc. These requirements can be defined through drawings, technical specifications or standards.

Material inspection: The supplier is required to provide qualified raw material certification, and check whether the raw material quality of aluminum alloy meets the specified standards and requirements, such as alloy composition, strength, etc. Process control: Monitor and ensure that suppliers follow the specifications of forging process flow, such as heating temperature, forging pressure, forging speed, etc. Focus on whether the process parameters are adequately controlled to ensure the stability of product quality.

Inspection method: Determine the appropriate inspection method and testing standards, such as size measurement, hardness testing, chemical composition analysis, metallographic inspection, etc. The supplier is required to inspect the product according to the specified inspection standards to ensure that the product meets the requirements.

Non-destructive testing: The use of necessary non-destructive testing means, such as ultrasonic detection, X-ray testing, etc., to detect the defects of aluminum alloy forgings to ensure that the product does not contain any internal defects.

Appearance inspection: pay attention to appearance quality, including product surface smoothness, cracks, bubbles, inclusions, etc. It should be carried out under the guidance of standardized surface inspection methods.

Documentation: Suppliers are required to provide complete quality documentation, including raw material certification, process parameters, implementation records, inspection reports, etc. These records help to trace and monitor the quality of the product.

Through the control of the above points, we can effectively ensure that the quality of the purchased 6061 aluminum alloy forgings meets the specified requirements and customer expectations. At the same time, establish and maintain close communication and cooperation with suppliers to jointly improve product quality and supply chain quality management level.
