Introduction
1. Standard Overview
GB/T 33142-2016 "Continuous Casting Copper Clad Aluminum Billet" standard specifies the terms and definitions, requirements, test methods, inspection rules, marking, packaging, transportation, storage and other contents of copper clad aluminum billet produced by continuous casting, and is applicable to the continuous casting of copper clad aluminum billet for processing copper clad aluminum flat bars (flat bars), flat wires, round wires and various special-shaped cross-section billets.
2. Standard Framework Comparison
| Standard Dimensions | GB/T 33142-2016 | Comparative Analysis |
|---|---|---|
| Terms and Definitions | Key terms such as copper-aluminum transition layer and coating layer volume ratio are clarified. | Aligned with GB/T 1.1-2009, new industry-specific terms are added. |
| Product Classification | According to the cross-sectional shape, it is divided into three categories: rectangle with rounded corners, rectangle with chamfered corners and circle. | The classification dimension is clear, which is convenient for production and inspection. |
| Technical Requirements | Including core indicators such as chemical composition, dimensional deviation, and interface shear strength. | Strictly control product quality to ensure stable material performance. |
3. Implementation Suggestions
Production Link:Strictly control the continuous casting process in accordance with the standard requirements to ensure that key indicators such as the thickness of the copper-aluminum transition layer and the volume ratio of the coating layer meet the requirements.
Testing stage:Establish a complete quality inspection system, equipped with necessary measuring equipment (such as density meter, shear strength tester) and analytical instruments (such as spectrometer).
Management stage:Develop a detailed quality management system, including raw material procurement, production process control, finished product inspection and unqualified product handling procedures.
