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: How do you tell if the wire is a real copper wire?
- Peel the wires off one end of the 2cm, then rub them slightly over the core with a sheet of white paper. If there is a black substance on the white paper, there is a lot of impurities in the copper core. And inferior copper wire color slants black, hardness is bigger. The copper twisted into a small circle, if too many impurities such as copper wire, copper clad steel wire will rebound, copper is not good rebound, circle. The copper wire is slowly straightened and restored, and when it is fully recovered, it turns out that your copper wire material is really good
- Q: Why do large transformers use flat copper wire instead of round copper wire?
- The maximum sectional area of the round copper wire is not enough, the flat copper wire does not waste space, and the winding transformer has a small leakage inductance.
- Q: Is it okay to cut copper wire by wire cutting?
- Any cutting injury conduction block, but the resulting in cutting aluminum alumina is a high hardness, poor conductive material, will be attached to the conductive block, influence the electrical properties, reduce processing efficiency, increase the wear of electrode wire and conductive block. When processing aluminum material, it is necessary to use oxalic acid to clean the conductive block for a period of time. It will improve the processing efficiency and protect the conductive block.
- Q: Tell me how to use copper wire to increase the WiFi signal
- The copper wire is wound on the antenna set by the WIFI and extended. Copper is a good conductor of electricity and electromagnetic waves propagate outward through the copper wire.
- Q: Will the weight change after the copper wire is burned?Is it heavy, light, or unchanging? What is the reason?
- Will become heavier, because copper (Cu) combustion in the air will produce copper oxide (CuO), the quality will increase
- Q: How do copper wire fixing tiles do?
- Generally used for wet process of glazed tile, low efficiency
- Q: Motor wire package, copper wire thickness affect power?
- Because of cost reasons so now by about 0.56 of the pump basic line of low cost for high power motor thickness above 5000W will affect the maximum performance is not so can change the diameter of root of the number of small motor so we repair the motor not only need to check the line or line weighing can easily coil large motor must be in accordance with the original motor module designed to do
- Q: UL 14AWG/18AWG wire, how many copper wire, the overall diameter of how many, cross-sectional area? What is the load current?
- A complement to the hdsr178 is that the outer diameter of the stranded conductor is a range of different pitches and different monofilament diameters that affect the outside diameter
- Q: Why change the thickness of copper wire can not change the current size of electromagnetic induction?
- Electromagnetic induction (Electromagnetic induction) refers to the phenomenon of conductor changes in magnetic flux, will produce electromotive force. The electromotive force is called electromotive force or electromotive force, if the conductor into a closed loop, the electromotive force will drive the flow of electrons, the formation of induction current, that is to say this the current and the induced electromotive force and resistance of bribery
- Q: What about brass, iron, silk, handicrafts, bicycle instruments?
- Next is the lower half of the body, where the pedals are mounted. The two small wheels are generally the same diameter as the front wheels, and the rear wheels are the same as those of the front wheels.
