You should use solder, not brazing. Brazing is used to join iron or steel products together.

Why must you preheat copper before brazing?
You usually do not braze copper, you solder it. If you were to use brazing rod on copper, the copper would have very close to the same melting point as the brazing rod. This makes it difficult to do. As far as preheating the copper, it needs to be hot enough for the brazing to flow.
What kind of rod is use for braze welding?
Brazing isn't welding - it's more like soldering. You use a rod made out of brass for the process of brazing.
How do you weld cast iron with an oxy acetylene torch with a cast iron rod?
I am not aware of a cast iron rod for oxy acetylene welding, I am for arc welding, For cast, I use a brazing rod, a brass or copper alloy, but what do I know. If there is a cast rod available, it would be the same process, get the cast you are welding hot almost to the point of melting, bring in the rod, heat it at the same place and bring both to a melting point. Work from that point along the crack or joint you are welding. ----------------------------------------------------------------------------------------------------------------- You need not use brazing rod for case iron welding. You get arc welding electrodes for cast iron. Use appropriate grade of rod for your case iron under welding.
How do you etch brass?
use of copper sulphate
Can you use copper and brass together on battery terminal?
Yes
What do people use to combine copper and tin?
Copper and tin could be melted and combined as an alloy, They can also be fastened together by some form of brazing, like soldering.
what is a property of metal which makes it a good material to use as a switch?
Copper and brass
Is brass the same as iron in weight?
no!!! Brass is an alloy of copper and tin; frequently other alloying elements are contained.
Why are the pins on a plug made of brass not copper?
because brass is generally tarnish resisant so it does not discolours easily and also because brass is not such expensive as copper <<>> The pins are make of brass because it is a harder metal than copper and will wear better through use over its lifetime.
Can you use brass as a dialectric union between copper and black iron pipe?
No, brass cannot be used as a dielectric union between copper and black iron pipe. Dielectric unions are typically made of materials that are not electrically conductive, such as plastic or rubber. Brass is a conductive material and would not provide insulation against galvanic corrosion between copper and black iron pipe.
Is it ok to connect copper pipe to brass pipe to steel pipe?
Yes, either by sweating it or with the right fitting on the copper for the brass to screw on. Yes by soldering , brazing, adapters such as Flagg flow TP fittings , Flaire, screwed , Mechanicl joints
What metals make up brass?
Brass is an alloy of copper and zinc. Arsenic and antimony are sometimes added to brasses that contain more than 20% zinc in order to inhibit corrosion. . Iron makes the brass harder. Other materials are also used in very small amounts such as silicon, manganese, phosphorus....
