Aluminium to Copper brazing

[MovingUpp]

will joints like these last a decade or more if submerged in boiling water? I'm looking to build a solar hot water heater...

[1crazyfocker]

thats not brazing..its just soldering..yes both are close to the same thing, but if you use solder then its soldering..lol still a good video but a little missleading. the two main differances between the twoo are 1. temp, (solder melts at a really low temp, almost like lead, in fact you can solder with lead as well) 2. when soldering all you have to do is touch one place on the pipe and it will flow all the way around the pipe "soldering it" with brazing you have to slowly work it around.

How much pressure can the joint handle?

Will it hold up to the new 410 pressures for air conditioners?

I want to ask compounds with aluminum brazing ???????

[2112lakshman]

what is the material used for flux 040

[raskinozturk]

merhaba aluminyum kaynağı ile ilgili fikir alışverişinde bulunmak isterim

[z044017]

what kind of flux are you using?

[441rider]

Flows very well,

[viktorhugo13]

Can you tell me the tubes composition., Do the flux and the filler metal work the same way for other aluminium and cooper compositions?

[billiejinman]

are you turkish?

[TheNumber1draftpick]

where's the marshmellows?

[danger52100]

What temperature you braze with, type of gas. type of flux I should have asked. would that hold up in refrigeration

[danger52100]

tell me the flux mixture you used

[cagrigurbuz]

flux is 040 mixed with water

[error204]

@cagrigurbuz tap water?

[cagrigurbuz]

@error204 pure, distilled or demineralized water

[DiabolicTut0r]

flux actually is not need when brazing but it can't hurt either

[TheDand2009]

you should try with oweld gas generators

[cagrigurbuz]

Oweld machines generates Hydrogen and Oxygen with electrolysis of water. Can be used, but due to Hydrogen flame has very high temperatures, there is a possibility to melt aluminium. Use of wide and soft flame is advised in this application, like propane.

[azzaza12345]

The Oweld flame's temperature is about 3600 degrees. You don't melt the alluminum because you go more fast. Thanks to this temperature the alloy goes deeper and the joints are more stronger. Moreover with Oweld gas generators you don't spend costs of gas any more and you will have a safe workplace (without risks of explosion, monoxide of carbon...).

[OTOPUN]

¿Como se llama el fundente?

[cagrigurbuz]

¿english?

[OTOPUN]

Si en ingles.

[error204]

@OTOPUN ahi dice 040 mezclado con agua. supongo qe sera agua destilada.

[appapo3]

The copper is in the aluminium swedge is that better than alumimium in a copper swedge.

[appapo3]

I would be interested to see this work on an old system where oil penetrated the pores of the copper and aluminium

[cagrigurbuz]

oil should be cleaned before brazing.

[RestauranteChines]

What is that white glue for?

[soundspark]

The "glue" is actually flux, to help the brazing metal stick good.

[CoolasIce2]

It looks like you are SOLDERING using the brazing flux.

huh?

[BogdanCatalinAlex]

that is iraqy :)) not turks. but iven iraqy's not iraq'i :D

[demircivaz]

Hocam eğitici bir video elinze sağlık

[kimlai62]

Ca you please reveal the name and manufacturer of the FLUX use. And the filler material, is this Aluminium filler matrial use or 60/40 Soldering wire used?? Thanks

[cagrigurbuz]

Manufacturer is ForteBraze and the flux name is 040.

Alloy composition used is ZnAl4 (Al: 4%, Zn: rest) wire.

For contact details please refer to the explenation on the right of the video.

Beyler bari aliminyumun daha profesyonelce yapılan bir lehimini gosterseydiniz. Sizce aliminyumu lehim etmede en uygun yontem Torch brazing mi? Bence aliminyumun ic yapısı falan bayagı bozuluyor.

[cagrigurbuz]

Bu kalınlıktaki Aluminyum boruları birbirine veya Alumninyum - Bakır birleştirilmesinde, özellikle buzdolabı üretiminde bir sorun yaşanmadan rahatlıkla kullanılıyor. Başka Aluminyum birleştirmelerinde diğer sert-lehim metodları kullanılabilir.

Burada kullanılan ZnAl4 alaşımı ile 450 °C'de işlem gerçekleşiyor, daha sık kullanılan AlSi12 alaşımıyla yapılan sert-lehim işlemi isie 560 °C'de.

[kingofadana]

Peki genel olarak soyle bir soru sorsam aliminyum parcaları birbirine lehim etmede en uygun yontem hangisi. Torch brazing mi yoksa baska bir metod mu? neden veya neden degil? tesekkurler. bu arada ben de cukurova makina muh. ogrencisi ya sen.

[PeugeotCommuter]

Further into my brazing research tonight I realized the compound is flux. I really wish I could find some fucking INSTRUCTIONAL videos on YouTube for brazing...

[PeugeotCommuter]

What is the mixture they made in the beginning? Is it some type of temperature gauge?

[cagrigurbuz]

Forteflux 040 brazing flux is mixed with pure water. 20-25% pure water is added on a balance.
