Powder

Metal alloys are atomized using inert gas to produce clean, homogenous, high-quality alloy powders.

 
 

Paste

Paste products combine alloy powders with suitable fluxes and binders for consistent application and ease of use.

 
 

Wire

Most Okai alloys are available in wire form and can be drawn to a variety of sizes. Available in coils and on spools.

 
 

Cut Pieces

Filler metals are available in strip, precut panels, chopped, or spherical form in a variety of sizes.

 
   

Flux and Chemicals

Okai manufactures a range of fluxes for any application; including liquid, cream and powdered flux.

 
 

HydroFlux Welder

Safe and clean, the HydroFlux welder generates it's own oxy-hydrogen gas from water brazing and soldering.
