What A-3 aluminium-zinc
cold spray powder is used for
A‑3 is an aluminium-zinc powder for low-pressure cold spray (LPCS, Cold Gas Spray). It is used to seal holes and cracks locally and to fill corrosion pits in aluminium, steel and cast iron parts.
Sealing radiators and heat exchangers
A material for locally filling holes and cracks in metal radiators, condensers and heat exchangers. The right choice depends on the substrate, the size of the damage and the operating conditions.
Corrosion pits and surface damage
A‑3 is used to fill local pits, chips and other surface defects in aluminium, steel and cast iron. Prepare the surface properly for the process before spraying.
Local cold spray repairs
For workshops and service teams that repair metal parts. The powder is a material for gas-dynamic spraying; it is not an adhesive, a filler or an aerosol zinc spray.
Repaired pressure components need an approved procedure and leak and strength testing. We do not define a universal hole size or working pressure based on the powder name alone.
