CUPRAL 103 N – Special Flux for Bronzes

Cupral 103 N is a special flux recommended to reduce oxides formation in aluminium bronzes, manganese bronzes, silicon bronzes and brasses con­taining aluminium.
The product also redu­ces the build-up of heavy drosses on crucibles and furnaces walls and creates a protective cover on metal bath, reducing gas pick-up.

Cupral 103 N is ideal to prevent the formation of aluminium, manganese and silicon oxides that give problems of metal fluidity reduction.

Cupral 103 N produces dry powdery dross; it is ideal for bale-out furnaces used in diecasting foundries.
