Introduction
In-depth interpretation of the standards for coated aluminum and aluminum alloy strips for electrical components
| Project dimensions | Technical requirements | Test methods | Qualification standards |
|---|---|---|---|
| Chemical composition | Meet the requirements of GB/T3190 | Spectroscopic analysis or chemical titration | Aluminum content ≥99.5% |
| Dimensional deviation | Clear tolerance range for thickness and width | Precision measurement method | ≤±10% (see the standard table for specific values) |
| Coating performance | Indicators such as film thickness deviation and pencil hardness | Surface test method and mechanical test | Film thickness ±1μm, hardness ≥3H |
Standard formulation background and technology evolution analysis
As electronic components develop towards miniaturization and high performance, the requirements for coatings on aluminum and aluminum alloy strips are becoming increasingly stringent. Based on actual application needs, this standard integrates advanced testing methods at home and abroad to form a comprehensive evaluation system covering chemical composition, dimensional deviation, mechanical properties and coating quality.
Implementation suggestions
- Select the appropriate grade and state:According to the specific needs of electronic components, select the grade (such as 1100H, 3003H) and state that meet the requirements of GB/T33229-2016.
- Strictly control dimensional tolerances: Especially in high-precision applications, it is necessary to ensure that the width deviation is ≤±5% and the thickness deviation is ≤±1.0μm.
- Strengthen coating quality inspection: Focus on film adhesion, solvent resistance and insulation performance. It is recommended to use GB/T9286 and GB/T23989 methods for testing.
