1. Electrochemical corrosion: Copper leh aluminum hian boruakah electrochemical corrosion a tawk thei a. An inhnaih chuan, a bik takin boruak lum takah chuan aluminum hian negative electrode angin hna a thawk a ni .
Corrosion a awm a, copper hian positive electrode hna a thawk a, chu chuan aluminum wire-a joint part chu a tichhe zauh zauh a, contact resistance a tipung bawk.
Pahnihnaah chuan, resistivity danglamna: Copper resistivity chu aluminum aiin a hniam zawk a, chu chu copper wire hian resistance a nei tlem zawk a, chutiang bawk chuan electrical conductivity a nei tha zawk tihna a ni. Copper wire leh aluminum wire te chu direct in a inzawm chuan .
Connect hunah chuan resistivity hrang hrang avang hian connection point-a resistance chu a pung ang.
Pathum, thermal expansion coefficient hrang hrang: copper leh aluminum te hian thermal expansion coefficient hrang hrang an nei a, chu chu temperature a inthlak chuan℃hrang hrangah an inzarpharh tihna a ni a, hei hian connection point-ah harsatna a thlen thei a ni.
Gap a siam a, chu chuan contact resistance a tipung a ni.
