Copper metals melt at 1981°F and to avoid melting of the base material, the required temperature for the brazing torch flame should be between 1100 and 1500°F. Is A Propane Torch Hot Enough To Braze?
Can you use a propane torch to braze metal?
A propane flame, mixed with air, burns at just 3,630 degrees Fahrenheit (1,999 degrees Celsius), making it a better choice for this application. Luckily, torch brazing isn't the only option. Induction brazing, which generates heat by passing electricity through a coil, is another way to join metal reliably.
What is the difference between torch brazing and welding?
Brazing can occur at lower temperatures than welding, though that doesn't eliminate the gas torch as an option. In fact, torch brazing is still common in certain applications, such as joining a tube into a fitting using copper or silver brazing filler metals.
Can You braze weld with a blowtorch?
Oxyacetylene blowtorches provide a more substantial source of heat and energy than propane or butane and can weld metals such as steel or braze aluminum. You might not be able to weld with just any blowtorch, but it is possible to weld with the right kind of blowtorch. Keep reading to learn more about braze welding.
How hot does brazing get?
Most brazing processes run at temperatures between 800°F and 2,000°F. For a strongest braze joint, the metals that are being joined together need to be at close to the same temperature.
Can I braze with a propane torch?
Here is the answer to whether you can braze with a propane / air torch. You can but you have to control the environment so that the heat loss to the atmosphere and parts is lower than the heat being put into the braze joint.
Can you braze with MAPP gas torch?
Mapp gas (a high-temperature mixture of petroleum byproducts) comes liquefied in compact canisters, which allows torches to operate for several hours, and some of the new instant-start brazing tips are quite inexpensive and very easy to use. Also, the gas canisters can be purchased locally at almost any hardware store.

What metals Cannot be brazed?
Heating metals, like silver or gold, to such high heat requires a lot of precision. It's more common for these metals to be soldered rather than brazed. Gold and silver can handle the lower heat better, and soldering can still give a good bond, even if it's not as strong.
Is brazing as strong as welding?
Unlike welding, brazing can be used to join dissimilar metals, such as gold, silver, copper and nickel. While brazed joints are strong, they are not as strong as welded joints.
Why did they stop making MAPP gas?
It is no longer used much in any large-scale industry – for larger scale users acetylene/oxygen is more economic than MAPP/oxygen when high flame temperatures are needed, and propane/air is more economic when big overall heating is needed.
What burns hotter than MAPP gas?
Acetylene is probably the hottest burning fuel gas available to us. It's also been around longer than propylene and MAPP gas. Historically it's the gas associated with flame hardening because of its hotter temperature.
Can I braze with a Bernzomatic torch?
The Bernzomatic BZ8250HT Hose Torch for Accessibility and Mobility is ideal for large diameter soldering, brazing and heat treating in hard-to-reach spaces. A hose and slender body provide maximum accessibility, while an adjustable swirl flame provides hot, efficient heat and fast soldering times.
How hot is a MAPP gas torch?
3,730 degrees FahrenheitMAP-Pro fuel has an in-air flame temperature of 3,730 degrees Fahrenheit.
What is hotter than a propane torch?
Propylene burns substantially hotter than propane all on its own, but this inherent heat advantage is also enhanced by a unique internal feature of this torch.
What kind of torch is used for brazing?
MAPP gas torches are small brazing kits suitable for DIY kinds of works and are used for manual brazing. They are ideal for brazing at low temperatures, and thin section brazing works. Oxyacetylene torches are the most popular and versatile type used in a home garage or small workshops.
What kind of torch is used for brazing?

What gas do you use for brazing?
For brazing there are generally two equipment options to choose from: oxygen/acetylene or air/acetylene. While alternate fuel gases are available, most contractors still use acetylene.
Can you braze with oxy propane?
Oxy Propane Oxygen and Propane fuelled kits are however, ideal for Silver Solder, Brazing, Cutting and Heating. So as long as you don't want to Weld, Oxygen and Propane is a great way to go! Oxygen + Propane produces a flame temperature of around 1800⁰C.
Can I braze copper with propane?
When sweating or soldering copper pipe, we've been asked about using either propane or MAP gas. In truth, both types of fuel will get the job done.
How Hot Is a Brazing Torch?
Copper metals melt at 1981°F and to avoid melting of the base material, the required temperature for the brazing torch flame should be between 1100 and 1500°F.
What is braze welding?
Braze welding is a type of welding where, instead of the two pieces of metal being fused at the site of the weld, a filler metal alloy is used to “patch” the two metals together like a sort of glue.
How Do Blowtorches Work?
How hot does a blowtorch get? The flame temperature of a blowtorch using butane is close to 1,430 °C (2,610 °F). When using propane, the blowtorch temperature is around 2,000 °C (3,600 °F)
Can Butane Torch Melt Metal?
Can butane torch melt metal? No, a butane torch does not create enough energy or heat to melt metal, such as steel. The heat produced by a butane torch is much lower than other welding torches and can not heat metals to a melting point.
Why Does My Blow Torch Keep Going Out?
Why does my torch keep going out? If your propane torch keeps switching itself off, the vent holes could be filled and starving the flame of oxygen to mix with the propane.
What Is The Best Torch For Soldering Copper Pipe?
What is the best torch for soldering copper pipe? Although you may use a propane torch to solder copper, MAPP (methylacetylene-propadiene propane) is usually your best bet because it reaches greater heat intensity than traditional propane torches.
Are Blow Torches Safe?
Blowtorches may be potentially hazardous. Its elementary logic that compressed gas and a flame source can be potentially lethal if not handled cautiously.
How to solder with a propane torch?
Soldering is a pretty easy and convenient joining process. So, you can solder with a propane torch by yourself. Let’s see how you can do it.
What is the difference between braze and solder?
Though braze and solder are both joining processes, they have some differences. So, let’s see what the differences are between braze and solder.
Is propane good for soldering? Is a propane torch hot enough to silver solder?
Yes, propane is pretty good for soldering. Generally, soldering needs a medium heat to operate. So, you can choose propane to solder effectively. Propane will reach up to the soldering temperature. You just need to keep the environment controlled to minimize heat loss.
Can you braze with a propane torch?
You can braze with a propane torch. Generally, the brazing process joins two metals permanently. So, you will need a high temperature. You can use a propane torch to braze. But if there is heat loss, the metals will not get heat. So, you have to control the environment to prevent heat loss.
What is the best way to braze a pipe?
The 2 best ways are Air Acetylene and Oxy Acetylene. There are benefits to both. The benefits to using Oxy Acetylene are: By far it has the hottest flame (5000 degrees vs. 2700 degrees) and can get the job done the quickest, especially on piping 3” diameter and up. It is sturdier than some plastic handled torches so it holds up better to abuse (ASCO handles would be the exception because of their heavy brass construction) and the gases last longer therefore you can braze / solder more joints without having to change the tanks.
How hot does copper melt?
Finally since copper melts at around 2500 to 3000 degrees there is less room for operator error so not to melt or distort the pipe.
What makes a propane torch burn hotter?
An air-only propane torch will burn at around 1,990 °C (3,614 °F). That is plenty of degrees to melt many metals like aluminum 660.3 °C and copper 1,085 °C, right?
How to get metal to temperature?
To really get metal to the temperatures where it can be worked at an anvil or even melted you really want a burner that lets you control the flow of gas and air and get a focused blast of heat.
