Product Advantages
Composition Control Improves Conductive Stability
A constant-temperature melting process is used at approximately 1083°C. Deoxidizers are added during the melting process, and impurities are strictly controlled. This keeps the copper alloy's conductivity fluctuation within ±2%, meeting the stability requirements of high-frequency signal transmission.
Precision Molds Ensure Cross-Sectional Consistency
Molds are manufactured using a CNC machining center, with cavity tolerances controlled to ±0.02mm. A constant-pressure extrusion system controls the extrusion rate deviation to less than 3%, ensuring stable forming and high dimensional consistency for complex, irregular cross-sections.
Annealing Optimizes Structural Performance
After extrusion, annealing at temperatures exceeding 400°C, combined with a controlled-rate cooling process, reduces residual stress by over 30%, significantly improving material elongation and meeting the reliability requirements of subsequent crimping and assembly processes.
Surface Treatment Enhances Environmental Adaptability
Finished products can be optionally plated or coated with an anti-oxidation coating, with a thickness of 5–15μm. Salt spray testing has proven corrosion resistance for over 72 hours, extending the product's lifespan in humid or corrosive environments.
Finishing And Quality Assurance
The extrusions later go through various final processing including cutting to final sizes, deburring, and surface treating. Surface treating can be plating or coating to obtain added corrosion resisting qualities. Tests in accordance with requirements in respect to quality control including check in order to dimensional requirements, check in respect to surface requirements, and tests to determine physical requirements are carried out to check that special-shape copper extrusions obtain design requirements.
