Aluminum Brazing Materials

Aluminum brazing materials are used for automotive heat exchanging and household air-conditioning manufacturing process. The products include Al flux-cored wire, paste, non-corrosive brazing flux and brazing rings etc.

Brazing Wire


Aluminum Flux-cored Brazing Wire/Rod

The Al Flux-cored brazing wire is consisted of Al-Si alloy and non-corrosive flux in the form of rod and preformed ring with advantage of convenient application and fast melting. They are widely used for the brazing for radiator, condenser and other thin-wall parts. The normal diameters include 2.0, 2.2 and 2.4mm etc. which could be used both flame brazing and CAB brazing.

Brazing Paste

Aluminum Brazing Paste

The brazing paste consists of AA4047 powder, non-corrosive flux and adhesives and used for secondary brazing for radiator, condenser and evaporator and CAB brazing of condenser accessories.

A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle. In most cycles it undergoes phase transitions from a liquid to a gas and back again. Many working fluids have been used for such purposes. Fluorocarbons, especially chlorofluorocarbons, became commonplace in the 20th century. Nowadays R134a is the most common refrigerant used in auto a/c systems as well as refrigerator compressors.
Ravimex International can supply you with pure refrigerants used in HVAC and refrigeration systems such as R134A, R22, R407C, R410A, R404A, R406A, R152A, R12, R142B, R143A, R32, R125 from our world-class supplier in China.
