Can you braze copper to copper or are the melting temperatures of copper and brazing spelter too close to each other?

Copper melts 1981 deg F Brazing alloys flow @ 900 -1,200 BTU all one has t do is pay attention to the flux if applicable

What temperature does solder melt when brazing copper pipe?
465 degrees Fahrenheit
Which two metals are an alloy of latten?
Almost any metals can make an alloy.It is easiest if the metals have similar melting temperatures.
What is the mechanical properties of copper?
Copper is ductile, malleable, and a good conductor of heat. It also has good brazing and soldering properties.
How do you extract copper by smelting?
copper is extracted by smelting by taking the copper out and melting it down.
Is 1240 degrees Celsius a high temperature?
Compared to common air temperatures, yes. It is equal to 2264 °F, which is higher than the melting points of the metals copper and gold, and only slightly lower than the melting point of cast iron (about 1260 °C).
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.
Is spelter magnetic?
No, spelter is not magnetic. Spelter is simply a synonym for zinc and is similar to copper or brass as well.
What two metals make up Spelter?
Composition of Spelter is - Copper- 90%, Zinc- 10%
Which brazing rod do you use when brazing copper to brass?
You should use solder, not brazing. Brazing is used to join iron or steel products together.
A flux is applied during a brazing operation primarily to?
When Brazing copper to copper flux is normally not needed When brazing steel or copper based alloys then the flux is used to help the wetting action (Better flow of the brazing alloy) and to prevent oxidation A typical rod would be Union Carbide 25 M or check out the AWS booklet
Is copper hard to weld?
You braze copper with a copper brazing rod. It does require a certain amount of skill and practice.
Is there any difference in sweating or braising cooper pipe?
yes there is brazing is done w silver alloy Brazing has a tensile strenght of 87,000 PSI and soldering around 16,000 Brazing filler metals require a melting point of 1,100 DEG Fsoldering around 600 Def F Using the correct type of brazing rod they are self fluxing on copper alloys and thus great for Oxygen and other medical gases and HVAC work

What are the main uses of brazing?
Brazing is the leading method of metal joining in many HVAC (Heating, Ventilation, Air Conditioning) appliances and equipment. It is also commonly used in joining or repairing copper pipes. As a general rule, brazing is used when solid, leak proof joints must be made without melting the base metals (which rules welding and soldering out.)Where a filler metal is heated above and spread between two or more close-fitting parts by capillary action. The filler metal is brought a little above its melting temperature while protected by a good enough atmosphere.Then it flows over the base metal (known as wetting) and then is cooled to join the workpieces together.The temperatures used to melt the filler metal is above 842 °F.
How do you braze brass tubing closed?
with a copper self fluxing brazing rod type suggested by AWS
