Copper Outer End Cap for High Voltage Low Current EV Fuse is a component used in electrical fuses designed for high voltage and low current applications in electric vehicles. The outer end cap is made of copper and serves as a terminal for the fuse, allowing it to be connected to the electrical circuit. Its design is optimized for high reliability and performance in the demanding conditions of EVS .

The T2Y2 Copper End Cap for Fuse exhibits good electrical and thermal conductivity, corrosion resistance, and excellent processing performance. It can be easily welded and brazed. The copper element content in T2Y2 is 99.95%, and the phosphorus content is only 0.02%. Meanwhile, T2 Copper End Cap is pure copper, which is named after its purple color. It contains minimal impurities that could otherwise reduce electrical and thermal conductivity. Though a small amount of oxygen does not affect its properties much, it is prone to "hydrogen disease." Copper End Cap is unsuitable for processing in a reducing atmosphere at high temperatures (>370 céim), mar shampla anáil agus táthú, agus úsáid ina dhiaidh sin .

The welding performance of copper stamping parts, including Fuse End Cap and Contact, is influenced by several factors. Firstly, high thermal conductivity requires a high-power heat source and preheating of the weldment before welding. Secondly, molten copper liquid has good fluidity, making flat welding position ideal, while spatial position welding requires a backing plate. Additionally, copper has a large coefficient of linear expansion, leading to significant thermal expansion and cold contraction during the welding process, resulting in significant deformation. Copper's susceptibility to oxidation leads to the formation of cuprous oxide, which reduces plasticity and causes cracks during crystallization. Lastly, the solubility cruthaíonn hidrigin i gcopar leachtach poill hidrigine le linn táthú, agus bíonn ocsaíd chuprous ag teochtaí arda ag freagairt le hidrigin agus le aonocsaíde carbóin mar thoradh ar fhoirmiú pore mura n -éalaíonn sé go leordhóthanach roimh sholadú .
