Solder wire is commonly used for manual soldering work and it’s a metal alloy that has two or more metals which are combined to produce a single metal. It is very well known for its benefits of combining together other types of metal by heating it by the process of heating it to its melting point to create a liquid bond before cooling it to its former stiffness. There are different types of solders available in the market like lead and tin, gold, silver, zinc, nickel, and rosin-core solder. As the name suggests these wires are used for physical soldering operations and also if you wish you can use them in automated purposes like die attach soldering and so on. There is different types solder wire like flux core solder and also it can be a used as a separate flux.
Flux core solder is a sort of metallurgy element that is used while the process of soldering two metals together. Flux is a motionless material that is responsible to prevent the development of metal oxides at intense temperatures. Flux is used in the process of soldering of joining two metals together and the process takes place below 425C. Brazing is another process where flux is used while joining the metal in between the melting temperatures which are above 800 degrees F. Flux used almost in every process like even in Welding, welding is the method of joining separate metals by melting the pieces together while adding a flux in between. With all the above mentioned points, it is clear that flux is filler metal that is used in various processes like soldering, brazing and welding and also it is responsible to prevent oxidation of the surfaces and it prevents the metal from being attached. With the help of oxidation the process of joining the metal deteriorates and that when flux comes in picture it is used to make the process stronger. Depending on the metals you want to join, you can choose from the variety of flux available in the market.
