HZ-S221 is a kind of copper and zinc brazing alloy, and available for gaseous flame brazing, high frequency brazing, furnace brazing, resistance welding etc. HZ-S221 has good welding performance, and it is widely used for brazing of copper and copper alloy, steel, copper nickel alloy, gray cast iron, cemented carbide etc. It could replace H62 filler metal and be used as wire of brazing brass. HZ-S221 is a special brass brazing filler metal that contains tin and silicon. While tin improves fluidity, silicon controls evaporation of zinc, and eliminates gas hole to get an excellent welding process. Because of good corrosive and toughness, HZ-S221 is often used by surface welding worn parts of metal, such as bearing valve sealing surface, propeller. HZ-S221 brass wire should work together with copper gas welding flux when oxyacetylene gas brazing.
Item Number:HZ-S221
Chemical Composition (%):Cu 59-61, Sn 0.8-1.2, Si 0.15-0.35, Zn Remain,
Melting Point:890-905°C
Recommended Temp.:910-945°C
Advantages and Usage:For brazing copper and copper alloy, steel and cast iron in the method of flame brazing, furnace brazing and induction welding
Caution:1.The surface of oil and oxide on the work pieces should be cleansed carefully before brazing .
2. Preheat the work piece to 400 to 500°Cbefore brazing.
3. Matching flux should be used together when brazing.
4.Neutral flame or slight oxidizing flame could be used when flame welding. Appropriate decrease welding temperature, increase welding speed, reduce residence time of molten pool in high temperature to lessen the evaporation and oxidation of zinc.
- Q: Why can't copper wire hang tin?
- If you do paste solder, tin to a little slower, do not look at all because of invasion, the solder paste containing acid, can be used in soldering slowly into the solder temperature above the melting solder paste to remove the oxide copper head, but also can make the paste and close contact to head to prevent oxidation, and all of a sudden after the invasion, the outside thread to evaporate paste is not to remove the oxide film and prevent oxidation effect
- Q: What are the advantages of copper wire galvanizing?
- After galvanizing, the contact resistance is small and makes it difficult to oxidize.
- Q: Copper wire welding craft, sailing boat production program, process results
- Copper wire welding crafts, this you can choose the following program, I think it should be the most appropriate, but also the fastest, there should be no easier than this
- Q: How is copper wire processed?
- Annealing tin machine (not for this customer), not all copper wires need to be tinned
- Q: How to remove copper wire in motor
- The motor is pulled out and the rotor is connected with two self - voltage regulators on any two lines of the stator winding, and then a current meter is connected. A regulator is able to regulate the current not too much.
- Q: Soft PVC plastic copper wire copper oxide black, is He Yuanyin
- This product has a strong catalytic inhibition of heavy metal ions aging ability, anti copper effect significantly and has good compatibility with resin, good dispersion, no migration, no pollution, water resistance, oil extraction is good, does not affect the electrical insulating properties of the resin and other advantages, is an ideal anti copper agent, antioxidant and anti copper dual role. The products are widely used in polyethylene, polypropylene and other copper core wire and cable insulation materials used in the production, communication cable, submarine cable, mine cable, power cable and other cable. This product can also be used in rubber, polyamide and other high polymer materials.
- Q: Can copper wire be oxidized in an instant?
- Can! You put copper wire in nitric acid, the effect is obvious
- Q: Why are wires made of aluminium or copper wire, and they are covered with plastic skins?
- The current flowing through the wire when the fever, which is not part of the heat utilization, and high temperature as well as security risks. Fever and resistance, the more resistance heating is greater. The same length and cross section of the wire, silver minimum resistance (you do household silver wire, I am afraid of?!), then is the copper wire, aluminum wire (you can accept them two price). But the aluminum is easily oxidized, most of them are now doing with copper wire.
- Q: Copper wire and plastic or copper wire and copper wire between how to bond, can do prison and fine?
- If you don't paint, you can buy the kind of AB glue, its color close to the color of copper, but must be on the cross section, not on the periphery or will be very ugly, and copper with copper contact surface, one side is flat, one side is semicircular, so be sure to use the small semicircle file section the file in a semicircle, or when you glue it will not very good-looking.
- Q: Why not use copper wire instead of stone pendant?
- In order to strengthen the firmness of the stone slab, some construction units do not need to do the hanging, but copper wire
