FAQ
What is the main difference between CCAA and standard CCA?
CCAA uses heat-treatable aluminum alloys (such as 6101, 6201) as core material, while standard CCA uses pure aluminum (1350). Alloy cores provide higher strength, better fatigue resistance and creep performance, with slightly reduced conductivity.
How much does CCAA cost compared to CCA?
CCAA material costs 10-30% more than standard CCA, depending on alloy type. CCAA-5005 adds about 10-15%, CCAA-5052 adds 15-25%, CCAA-6061 adds 20-30%. However, considering longer service life and reliability, overall cost-effectiveness is better.
What applications are suitable for CCAA?
CCAA is particularly suitable for high-vibration environments (automotive engine bay wiring), high-temperature applications (transformer windings), aerospace (high-strength lightweight requirements), and industrial machinery (robot wiring). Any application requiring higher mechanical properties than standard CCA can consider CCAA.
How is CCAA's conductivity?
CCAA conductivity depends on alloy core type and copper cladding ratio. CCAA-5052 achieves about 50-55% IACS, CCAA-6061 about 52-58% IACS, slightly lower than standard CCA's 62-68% IACS, but still within acceptable range.
