About Vibha International

Vibha International has been established with the primary aim of delivering industrial brazing equipment sourced from top market leaders who believe in delivering top-class quality products at the best price.

Copper Brazing

Greater Joint Strength For High-Temperature Systems

The use of copper brazing is for when greater joint strength is needed or for systems that operate at 350 degrees or higher. Typical uses include: fire protection, air-conditioning and refrigeration.

  • 🔥 350 ℃+ Systems
  • ❄️ AC & Refrigeration
  • 🚒 Fire Protection
  • ⚡ Good Electrical Conductivity

Copper Brazing Rods are of 2 types:

BCup Copper–Phosphorus BAG Silver Brazing Alloys
Type 1 · BCup

BCup Copper Brazing Rods

Copper–Phosphorus alloys — the most commonly used brazing filler metals for copper tube & fittings.

About the BCuP Alloy Family

The most commonly used brazing filler metal types used to join copper tube and fittings fall into two distinct categories: BCuP Alloy (pronounced b-cup) — where the B stands for Brazing, Cu is the chemical symbol for Copper, and P is the chemical symbol for Phosphorous.

BCuP series brazing filler metal has good electrical conductivity at the joined points, good mechanical properties, and good anti-corrosion properties against acid — it has weakness for iron.

  • Self-fluxing on copper-to-copper applications
  • Good electrical conductivity at joints
  • Acid & corrosion resistant
  • Note: Flux should be used when brazing brass or bronze

Solbraze-BCup-2 · Copper Phosphorus Brazing Rod

BCuP-2 Phos-Copper low-cost alloy is suitable for most copper-to-copper or brass joints where good fit-up exists, and the assemblies are not subject to vibration or movement. Developed primarily for use on copper, this alloy may also be used on other nonferrous copper base alloys. By virtue of its phosphorus content, this product is self-fluxing on copper-only applications.

Typical Applications: refrigeration units, electrical conductors, copper and brass fittings, air conditioning apparatus, copper and brass equipment.
⚠️ *Flux should be used when brazing brass or bronze with this product.

Solbraze-BCup-6 · Copper Phosphorus Brazing Rod

BCuP-6 is a low-cost brazing filler metal suitable for joining copper to copper and copper to copper alloys where critical impact or vibration stresses are not encountered in service. It should be used on assemblies where good fit-up can be maintained.

Typical Applications: refrigeration units, electrical conductors, copper and brass fittings, air conditioning apparatus, copper and brass equipment.
Cu-Zn · Phosphorus

Solbraze-BCup-6 · Copper-Zinc Phosphorus Brazing Rod

Copper-zinc brazing filler metals are mainly used in fast-heating brazing processes such as flame brazing, high-frequency induction brazing and resistance brazing.

It is used to braze copper, copper alloys, steels, cast iron and cemented carbide.

⚠️ Contaminants on the surface, such as grease and oxides, must be removed thoroughly before brazing. Addition of flux is necessary during brazing in order to obtain optimal brazed joints.
Type 2 · BAG

Copper Brazing (BAG) — Silver Alloys

Cadmium & cadmium-free brazing alloys with an excellent combination of melting range, capillary flow and mechanical properties.

Cadmium & Cadmium-Free Range

We offer a wide range of cadmium / cadmium-free brazing alloys which have an excellent combination of melting range, capillary flow and mechanical properties. These alloys are recommended as economical alloys where the presence of cadmium is acceptable.

We are also offering a range of cadmium-free alloys, keeping in view the requirements of our end users — which mainly consist of the food and beverage industry. These alloys are suitable for use on most ferrous and non-ferrous materials. We offer numerous material compositions for general purpose and specialty applications, available in strip, wire, rod or ring form.

  • Economical cadmium alloys where acceptable
  • Cadmium-free alloys for food & beverage industry
  • Suitable for ferrous & non-ferrous materials
