Once the copper layer is damaged, the aluminum base is exposed and is more susceptible to corrosion, resulting in a decrease in conductivity or even breakage.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">2. <strong>High humidity environment (long-term heat and humidity)<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Such as: tropical rain forest areas, underground humid places<\/strong><\/li>\n\n\n\n<li>Reason: Long-term moisture will cause the copper layer to oxidize and fall off, and at the same time the risk of electrochemical reaction of aluminum will increase, resulting in &quot;aluminum corrosion&quot; phenomenon.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">3. <strong>High temperature environment<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Such as: in a closed box, in an outdoor high temperature exposure area<\/strong><\/li>\n\n\n\n<li>Reason: High temperature will accelerate the &quot;delamination&quot; and bulging caused by the difference in thermal expansion between the copper layer and the aluminum base; exceeding the operating temperature range (&gt;105\u00b0C) may also cause material aging.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">4. <strong>High frequency vibration\/frequent mechanical shock<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Such as: transportation equipment, high-frequency moving parts of electric vehicles<\/strong><\/li>\n\n\n\n<li>Cause: When the copper layer is not firmly bonded, long-term vibration will lead to metal fatigue, causing the copper layer to peel off or crack.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">5. <strong>Critical circuits requiring high current or extremely low resistance<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Such as: high-precision instruments, trunk transmission lines<\/strong><\/li>\n\n\n\n<li>Reason: Although copper-clad aluminum can meet certain conductivity requirements, its conductivity is still lower than that of pure copper and is not suitable for use in the main current channel with extremely high electrical performance requirements.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Summarize:<\/h3>\n\n\n\n<figure
