Material properties of Fuse End Caps Brass material

The performance of H65 Brass Inner Cap is between H68 and H62, the price is cheaper than H68, and it also has higher strength and plasticity, Brass Inner End Cap can well withstand cold and hot pressure processing, and has a tendency to corrosion cracking.Mainly used in the production of EV Fuse Brass Inner Outer Cap,PV Fuse Outer Brass Cap, Nickel Plated Brass End Caps,mainly used as electrical, thermal, corrosion-resistant equipment.

1.Brass of Fuse Inner Cap has very good plasticity and high strength, good machinability, easy welding, and general corrosion stability.

2.Brass of Brass End Cap has high strength and plasticity, can well withstand cold and hot pressure processing, and has a tendency to corrosion cracking.

3.H65 brass of Fuse End Caps has good mechanical properties and wear resistance, and can be used to manufacture precision instruments and Fuse Contact parts.

The differences between electroplating matte (fog) tin and bright tin of Fuse Contact Cap

Matte tin plating Fuse Copper Contact Cap is a coating with good solderability and certain corrosiveness.Because of its easy welding and good conductivity, it is widely used in electrical and electronic parts Copper Outer Cap for Industrial Power Fuse and Copper Outer Cap for gG gL Fuse that need to be welded.


1. Matte tin plated Copper End Caps surface is dull and dull. Bright tin Copper Cap surface is bright and beautiful.

2. Matte tin plating crystals Outer Cap are coarser. Bright tin Outer Cap is added with brightening agent to make the crystals finer and shiny.

3. Matte tin Fuse End Plate welding is better. Bright tin Fuse End Plate solders poorly and tends to produce tin whiskers.

4. Fog tin Round Polished Copper end Cap has better high temperature resistance, less bright tin Fuse Copper end Cap, and is prone to the problem of secondary melting of tin.

5. The cost of fog tin Fuse Copper Cap Fitting is higher than that of bright tin Fuse Copper Cap Fitting.

6. Matte tin Fuse Metal End Cap is generally used for soldering terminals or SMT parts.Bright tin Fuse Metal End Cap is used in places with appearance requirements and cold-pressed connection terminals.

Brazing inspection methods for the Fuse Copper End Caps and Contact

⒈ Visual inspection

The visual inspection is to check the surface quality of the brazed joint Copper Pipe Cap with the naked eyes or a low-magnification magnifying glass, such as whether the solder fills the gap, whether the exposed end of the brazing seam forms a fillet, whether the fillet is uniform, whether the surface is smooth, whether there are cracks, pores and other external defects.

2. Surface defect inspection

Surface defect inspection methods of Copper Pipe End Cap include fluorescence inspection (color inspection) and magnetic particle inspection. They are used for inspection of appearance and for inspection of brazing surface defects such as cracks, porosity, etc., which cannot be detected visually. Fluorescence inspection is generally used for the inspection of small workpieces like Fuse Copper Cap, color inspection (partial inspection of workpieces) for large workpieces like Copper Cap for European Cylindrical Fuse Link, and magnetic particle inspection is only used for magnetic metals.

⒊Internal defect inspection

Radiographic inspection, ultrasonic inspection and compactness inspection are mainly used for Plated End Caps,like Silver-plated Copper End Caps ,Fog Tin-plated Copper End Caps,Bright Tin-plated Copper End Caps,and so on.Radiographic inspection is a common method for inspecting the internal defects of important workpieces Copper Outer Cap for Eaton Bussmann Fuse. It can show pores, slag inclusions, lack of brazing in the brazing seam, and cracking of the brazing seam and the base metal Fuse Outer Cap. The range of defects found by ultrasonic inspection is the same as that of radiographic inspection.
