CuMn13Al7

INTRODUCTION 

CuMn13Al7 is used in applications that require resistance to cavitations, erosion, and corrosion.This alloy is also used to join or repair high-strength bronzes of similar chemical composition and for high-strength repairs of cast iron. Best used for the overlay welding of iron-casting and low-alloy steel. Also suited for welding marine propellers.

Spray process

Arc Spray

Arc spraying is the use of electric arc burning in two consecutive fed between the wires to melt the metal, with a high velocity gas stream molten metal atomization, and the atomization of the sprayed metal particles so that they accelerate the work to form a coating technology .

Flame Spray

The use of a flame as the heat source, the metal and non-heated to a molten state, forming a mist flow in the state of high-speed air jet to the substrate, the injection of the molten minute particles impact upon the substrate above, plastic deformation, into a sheet shape superimposed sedimentary layers.
