T2Y2 Red Copper Contact for Fuse material properties
1.The copper of Fuse Terminal Contact has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and Fuse Terminal can be welded and brazed. Contains less impurities that reduce electrical conductivity and thermal conductivity, and trace oxygen has little effect on electrical conductivity, thermal conductivity and processing properties.
2.The copper terminal of EV Automotive Fuse Terminals High purity, conductivity not less than 98%.
3.The Copper of Fuse Terminal Contact is No "hydrogen disease" or very little "hydrogen disease"; good processing performance and welding, corrosion resistance and cold resistance.
4.Fuse Link Contact Copper material has good welding performance and cold bending performance, generally no "hydrogen disease" tendency, can be processed and used in a reducing atmosphere.
5.The addition of a small amount of silver to copper can significantly increase the softening temperature (recrystallization temperature) and creep strength, with little reduction in copper electrical conductivity, thermal conductivity and plasticity. The aging hardening effect of silver copper is not significant, and cold work hardening is generally used to improve the strength. The copper terminal of Fuse End Blade Ferrules has good wear resistance, electrical contact and corrosion resistance.
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.
Characteristics of new energy Fuse Copper Contact and Outer Cap brazing
Brazing Fuse Copper Contact and Brass Outer Cap refers to a welding method in which the filler metal and the weldment below the melting point of the weldment are heated to the melting temperature of the filler metal at the same time, and then the liquid filler metal is used to fill the gap of the Fuse Copper Terminal and Brass Cap to connect the metals. During Fuse Contact Cap brazing, the oxide film and oil stains on the contact surface of the base metal should be removed first, so that the capillary can play a role after the brazing filler metal is melted and increase the wettability and capillary fluidity of the brazing filler metal. According to the different melting points of the solder, brazing is divided into brazing and soldering.
Brazing process of the Fuse Copper Contact and Brass Fuse Cap: The workpieces Fuse Copper Contact Cap that have been cleaned on the surface are assembled together in a lap joint pattern, and the solder is placed near or between the Fuse Contact Copper and Cap Brass joint gaps. When the workpiece and the solder are heated to a temperature slightly higher than the melting point of the solder, the solder melts (the workpiece is not melted), and is sucked in by capillary action and fills the gap between the solid workpieces Fuse Link Contact and Inner End Cap. The liquid solder and the workpiece metal diffuse and dissolve with each other. A brazed joint is formed after condensation.
1.The surface of the joint Copper Cap and Fuse Terminal is smooth, the air tightness is good, the shape and size are stable, the structure and properties of the weldment do not change much, and the same or different metals and some non-metals can be connected. During brazing Fuse Contact and Outer End Cap, the whole workpiece can also be heated, and many welds can be welded at one time, which improves the productivity. However, the strength of brazing joints is low, and lap joints are mostly used, and the joint strength is improved by increasing the lap length; in addition, the preparation work before brazing Copper Contact and End Caps is relatively high.
2.In order to make the brazing part Fuse Copper Contact and Copper Cap firmly connected and enhance the adhesion of the brazing filler metal, flux should be used during brazing to remove oxides on the surface of the brazing filler metal and the weldment.
3.Brazing Copper End Caps and Contact uses an alloy with a lower melting point than the base metal as the brazing filler metal. When heated, the brazing filler metal is melted and filled and kept in the joint gap by wetting and capillary action, while the base metal is in a solid state, relying on liquid brazing filler metal and solid mother metal. The mutual diffusion between the materials forms a brazed joint. Brazing Fuse Copper Contact and Cap Copper has little effect on the physical and chemical properties of the base metal, less welding stress and deformation, and can weld dissimilar metals with large differences in performance, and can complete multiple welds at the same time.
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.
