⚡ ARMACK Borax powder for brazing and welding

ARMACK AMASAN Borax is a professional flux in the form of a white powder intended for brazing and welding. It is used primarily when making joints from steel, cast iron, copper and brass, as well as for welding brass.

The flux supports the proper brazing process by preparing the metal surfaces for joining and making it easier for the filler metal to flow. It is a practical addition to brazing fillers used in workshops, production facilities, service centres and during installation work.

✅ Key benefits of ARMACK Borax

• Designed for brazing – suitable for professional brazing work.
• Can be used when welding brass.
• Wide range of materials – suitable for steel, cast iron, copper and brass.
• Fine powder form – allows convenient dosing of the flux at the joint.
• Supports filler-metal flow and proper wetting of surfaces during brazing.
• 500 g pack – suitable for regular workshop and service applications.
• Intended for use with popular brass-based brazing fillers.

✅ What is borax used for during brazing?

During brazing, proper surface preparation is crucial to the quality of the joint. Borax acts as a flux, supporting the brazing process and making it easier to distribute the molten filler metal correctly between the components being joined.

It is particularly useful when working with materials that require an additional flux, where the filler metal alone does not provide suitable conditions for making a proper joint.

✅ Applications

ARMACK AMASAN Borax can be used, among other applications, for:

• brazing steel components,
• brazing cast iron,
• brazing copper components,
• brazing brass,
• welding brass,
• workshop and repair work,
• construction work,
• professional installation and service applications.

✅ Use with ARMACK brazing fillers

The manufacturer recommends using borax, among others, with the following fillers:

• ARMACK CuZn40Si,
• ARMACK CuZn39Sn.

This combination of flux and suitable filler metal allows the brazing process to be carried out correctly on components made, among other materials, from steel, cast iron, copper and brass.

✅ Important information on use

The flux should be selected according to the type of filler metal and the material of the components being joined. Before brazing, the surfaces should be properly cleaned of dirt, grease and layers that could hinder proper wetting by the filler metal.

Suitable personal protective equipment must be used during work, and the information in the product documentation and safety data sheet must be followed.
