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: Fuse electric knife with copper wire can be replaced?
- If the blind with ordinary wire wire or wire to use knife closing, when overload occurs when the circuit, the knife will lose the role of insurance in line, meter fire burned, It is often seen. caused fatal accidents; if there is a short circuit, is more dangerous, arc severe burns will even cause death of malignant operation the accident of closing, so the current technical specification for electrical safety provisions in any case must not be allowed to use copper wire instead of fuse.
- Q: How to distinguish between genuine and multicore copper wires?
- Is it a single core or multicore cable?. In fact, as long as the square is equal to the number that can be used, more cores generally smaller cross-sectional area, soft, practical lighting circuit installation, single wire convenient wiring, the cross-sectional area is relatively large, suitable for large power line socket etc.. Now the wire market successfully, the quality of the general consumers to find the best uneven in quality, a large shopping malls, shops to buy, do not buy cheaper because some unknown manufacturer of wire to avoid all kinds of trouble after installed after the.
- Q: Tinned wire, copper wire, when immersed in tin after a period of time, why would ash and so on?
- Ash is oxidized, which is what happens when the temperature is high and the humidity is longer.
- Q: There are several copper wires in the set of coils of the washing machine. Can they be welded? Can I use it well after welding?
- No, not on the welding, because that is not the original insulation insulation paint, and if burned out part of the copper wire, the other also has a lot of burnt but not burning it, that is very dangerous.
- Q: What's the difference between hard core copper wire and soft wire copper wire? Which is better?
- Soft copper wire carrying capacity is greater than hard copper wire.In the same section, the surface area of the soft copper wire is much larger than the surface area of the hard copper wire. Because of the skin effect (when there is AC conductor with alternating current or alternating electromagnetic field inside the conductor, the uneven distribution of current, current in conductor "skin", that is to say the current focus on the appearance of the conductor layer is close to the conductor surface, the more current density phenomenon than hard line). The current carrying capacity of soft copper wire. In addition, the soft copper wire is better than hard copper wire because of its large surface area.
- Q: The copper wire in the charger is broken. Why can you use it?
- As long as the inside two to touch, all right, do not buy in the past is a live, the voltage may be 12V, with caution
- Q: Winding method of multi stranded copper wire butt joint
- Directly below the 10 square fork connecting, more than 10 square with copper pipe connection
- Q: Wire, copper wire, why some copper wire can be easily twisted together, and some twisted together and bounced back to the original state?
- You don't agree by default. Model letters are subject to national standards and are not optional. Such as BV, BVR, ZR-YJV, NH-YJV, and so on. RX is a rubber insulated wire and is now seldom used.
- Q: What's the difference between a copper tube and a copper wire in a cable?
- Copper tube is also called copper tube. A tube of non-ferrous metal that is a pressed and drawn seamless tube. The copper pipe has a strong corrosion resistance, and has become the first choice for modern contractors in the installation of plumbing, heating and cooling pipes in all residential commercial premises. Copper pipe is the best water supply pipeline.
- Q: About using copper wires as fuses
- Copper wires can be used as fuses. Copper sheets can be used as fuses! Fuse insurance is not insurance, the key is to see the fuse current instead of material, thin thin copper wire, the excessive current, as long as the wire diameter and the fuse current adapter is no problem (read more people do not adapt to this point).
