Material properties of Tin Plated Copper End Caps for PV Fuse

(1) The Fuse Knife Contact Copper has good electrical conductivity, second only to silver among various metals; the purer the copper, the higher the electrical conductivity, that is, the smaller the resistance.

(2) The Fuse Terminal Red Copper has excellent thermal conductivity, second only to expensive metals silver and gold in this regard.

(3) The Fuse Blade Contact Copper has good corrosion resistance in the atmosphere, fresh water and sea water, so copper pipes and utensils can be durable for a long time.

Different coating for Fuse Copper Cap

The difference in performance between tin plating, nickel plating and chrome plating on the copper Cap and Contact for Fast Acting EV Fuse surface: the hardness of the coating is chrome plating > nickel plating > tin plating; the appearance brightness (for a long time) is chrome plating > nickel plating > tin plating; chemical stability is nickel plating > chrome plating >Tinned.

The nickel-plated layer has high hardness and good chemical stability, so it is generally due to the coating of electronic device lead materials;

The tin-plated layer is soft and easily damaged, but it has good solderability, so it is often used as a coating for the soldering ends of Cap and Contact for Battery Pack Fuse.

Principles and advantages of copper or brass resistance brazing of fuse contact caps

Brazing is a connection method that keeps the temperature between the melting point of the solder and the melting point of the base material Fuse Cap and Contact Resistance welding, fills the gap between the base material and the base material by melting the solder, and solidifies and crystallizes to achieve interatomic bonding. Resistance brazing Fuse Contact Cap is a welding method in which two workpieces are placed between two electrodes and pressed together and energized, so that current flows through the workpiece Fuse Cap and Contact Tin welding, and the workpiece Outer End Cap and Terminal Welded Assembly Set itself generates resistance heat to heat the workpiece and melt the solder.
