Brazing filler metals

"Brazing filler metal "is a metal material that acts as an adhesive when "brazing" to join metals together. Generally, seven types of brazing filler metals that conform to JIS standards are used, but it is important to select a brazing filler metal that matches the base material to ensure reliable joining. We propose and sell the suitable brazing filler metal for our customers' welding and joining in Thailand. Custom-made products are also available.

Fluxes

Flux acts as a joint promoter during brazing and welding. It also prevents re-oxidation of joints. It is available in forms such as powder, paste, and liquid, depending on the application. It is important to choose the appropriate flux for the metal to be joined, as it will affect product performance and productivity.

Auxiliary material

While brazing can be done without damaging the base metal, it requires specialized knowledge. In addition to brazing filler metals, fluxes, heating sources, etc., various auxiliary materials are required to achieve highly accurate brazing. We sell various auxiliary materials in Thailand according to the brazing method and base material.

SAMURAI ASIA TOP

Paste flux (for silver brazing, brass brazing)

The paste type flux is sticky and can be applied precisely to the area to be brazed. The flux is selected according to the active temperature range and operating conditions. We have "for silver brazing" and "for brass brazing". Among them, the type with excellent heat resistance and the type with excellent ability to remove oxides from the base material are highly active, so they are suitable to be used for brazing stainless steel. If you are looking for various welding materials in Thailand, please contact us.

Liquid Flux

Oxidation of copper and copper alloys forms an oxide film that inhibits the brazing filler metal from wetting (spreading of the molten brazing filler metal on the surface of the base material), which adversely affects brazing. Our liquid flux controls the oxide film on copper and copper alloys and promotes joining using phosphorus copper brazing filler metal. If you are looking for various welding materials in Thailand, please contact us.

Aluminum brazing

Aluminum brazing filler metal is roughly divided into "hard brazing filler metal" and "soft brazing filler metal". "Hard brazing filler metal" generally has excellent corrosion resistance, and the joint is stronger than the base metal. We sell aluminum materials that are ideal for controlling erosion (local corrosion) and for brazing in a furnace. We also have a wide range of paste brazing filler metals. If you are looking for welding materials in Thailand, please contact us.

Phosphorus copper brazing

It is mainly used for joining copper and copper alloys. Phosphorus has a "self-fluxing action" that reduces the oxide film on the surface of the base metal during brazing, so in the case of welding and joining pure copper, the flux is not needed. Another feature is that it is relatively low in cost despite having the same effect as silver brazing. We sell various types of phosphorus copper brazing in Thailand.

Copper brazing

It is a brazing filler metal made of pure copper. Since it has excellent wettability (the way the molten brazing filler metal spreads on the surface of the base material), which allows for good brazing without affecting the base material. If you are looking for a high-quality copper brazing in Thailand, please contact us.

Brass brazing

Brazing filler metal made of an alloy of copper and zinc with additive elements, also referred to as shinchu (brass) brazing. It is mainly used for brazing of similar metals such as copper and copper alloys. It also has good joining properties with iron-based alloys. As the electrical conductivity, boiling point, thermal conductivity, corrosion resistance, processability, etc. differ depending on the ratio of zinc contained in the brazing filler metal and the additive elements, it is important to select brass brazing in accordance to the purpose. If you are interested in purchasing brass brazing filler metal in Thailand, please contact us.

Silver brazing

A brazing filler metal with high strength and excellent versatility. It can be used for most metals other than aluminum and magnesium. It is suitable for brazing dissimilar metals as well as metals with ceramics. There are many types of silver brazing, each with different properties. We will propose the most suitable silver brazing for the base material, including paste brazing filler metal, in Thailand.

Paste brazing filler metal

It is a paste-like brazing filler metal mixed with flux and other ingredients. It is also suitable for automatic brazing because a dispenser can be used to ensure uniform brazing. It also supports an atmosphere furnace that brazes with gas (hydrogen, nitrogen, argon, etc.) and in-furnace brazing using an air furnace or vacuum furnace. If you are looking for welding materials in Thailand, please contact us.

Flux cleaner

Flux is essential for reliable brazing, but its residual flux (residue) can adversely affect the base metal and must be removed after joining. Our flux cleaner can be used on various metals. It cleans and removes residual flux with a quick cleaning effect. If you are looking for various welding materials in Thailand, please contact us.

Brazing flow stopper (Anti-flow)

When brazing at high temperatures, excess brazing may flow out and eat into the base metal, which could cause alloying. It is the "Brazing flow stopper (Anti-flow)” that prevents unnecessary brazing from flowing out and achieves more precise brazing. Our products are in paste form and can be applied where needed with a brush. Also, because it is water-soluble, it can be easily removed after joining.
