BLUEBRAZE

BlueBrazes are silver alloys with excellent flow properties and a low melting point.
They are suitable for joining any type of steel, copper and copper alloys, or nickel and nickel alloys,
and can be applied using any brazing and heating method.

ADVANTAGES

Silver content by 10% to 21% lower than standard alloys;

Same brazing temperature as standard alloys;
Lower density means, for the same kg, you get more metres of brazing alloy
than you would with standard alloys

APPLICATIONS:

Air conditioning
Refrigeration
Heating
Tools

BLUEBRAZE ALLOYS AIR-CONDITIONING AND REFRIGERATION MARKET

BlueBrazes 3510, 3010, 2410 and 2010 are an alternative to standard BrazeTec silver alloys 4576, 4076, 3476 and 3076
with the same brazing temperature and same high-quality characteristics but with a silver content reduced by 10%.
In addition, they have a lower density, meaning that, for the same number of kg of material purchased,
you get at least 5.5% more material

BLUEBRAZE ALLOYS TOOL MARKET

BlueBraze 2810, 28/Cu and 28Cuplus alloys have been developed specially for applications in the industrial tool market. Silver content has been reduced by 21% compared to the most widely used alloy in the market (ISO 17672: Ag 449),
without the need to change parameters in the existing brazing process.
The new BlueBraze alloys have a working temperature of 710 °C, which ensures that brazing features excellent capillary action without damaging the microstructure of the base materials (e.g. steel and hard metal).
The cut resistance of the tool brazed with the new alloys is equal to or greater than resistance values encountered
using the market’s main standard alloys.
