Product Uses and Applications

Meta-Braze 281 is self fluxing on copper to copper joints and offers an excellent combination of ductility, flow and cost. It has medium flow characteristics making it suitable for refrigeration installations and for the wider gaps found in HVACR pipework. It is a comparatively ductile alloy meaning that joints can be maniulated post brazing and can withstand a degree of vibration in service. With 5% silver content Meta-Braze 281 provides an affordable solution for manufacturers of heat exchangers and installers of larger refrigerated pipework systems. Meta-Braze 281 can be used in service conditions down to -50°C.
