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 are shielded cables woven with tinned copper wire?
- Flame retardant flexible cable for DC cable communication power supply is flame retardant flexible cable used in power supply and distribution system of Communication Office (station) and high-rise building power supply.
- Q:How many mm copper wires can replace 10A's fuse?
- This will not work. It will fuse copper wires and cause fire
- Q:The net is inserted into the crystal head. Do you want to leak the copper wire first?
- Under normal circumstances, the line is not exposed, and this is a standardized approach.Of course, in many cases, the amount of grasp is not very accurate, as long as some slightly exposed head. The crystal is no problem, just not pretty. For a long time it is possible to cause dirt inside the crystal head, resulting in poor communication.
- Q:The red hot wire into the anhydrous alcohol smell pungent odor
- The copper wire in the alcohol lamp burning to heat, Cu is oxidized to CuO
- Q:A material like copper wire that passes through an electric current. We call them why
- Metals are called conductors. Plastics are called insulators
- Q:Slow wire cutting machine wire consists of several series?
- Brass wire. Galvanized brass. Galvanized yellow, mainly used in diameter below 0.15 fine wire processing.
- Q:Why can't fuse be replaced by copper wire?
- The original, although also a fuse wire, but it is different from the ordinary copper wire of.x0d, it is soft and is composed of lead, antimony, lead or tin made of low melting point alloy. Its resistivity is relatively large, relatively low melting point, are afraid of heat. Due to the thermal effect of current, as long as the current through the the fuse exceeds the rated current of the fuse, to fuse current, the fuse will be quickly fuse, automatically disconnect circuit and power. So, strong current cannot enter the user's home to
- Q:How to recognize the authenticity of household copper wire
- Look, copper, copper light brightness is higher, copper is better, and the brightness of the uniform, shiny, no hierarchy, qualified copper core wire, copper core should be purple, shiny, soft feel. If you can cut off a small plastic sheath, carefully check the inside of the copper wire, copper wire with the palm top touch, feel should be smooth without pain, feel is soft, and the copper wire copper core and purple black, yellowish or whitish, impurity, poor mechanical strength, good toughness. A little force will be broken, and often wire breakage phenomenon. When you check, you just peel the wire off 2CM, then rub it with a sheet of white paper on the copper core. If there is a black substance on the white paper, there is a lot of impurities in the copper core. In addition, the inferior insulated wire seems to be very thick. In fact, most of the insulation is made of recycled plastic. Over time, the insulating layer will age and leak.
- 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: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
