Legor® SF928CH - Casting Alloy 925 Silver

Legor's SF928CH is a master alloy for 925‰ silver jewelry, designed for lost-wax casting in closed and open systems. This formulation can be alloyed from title 925‰ to title 935‰. It is particularly suitable for stone-in-place casting. The hardness of 925‰ silver alloyed with SF928CH can be moderately increased by means of a heat treatment. Please refer to the technical chart for information on the correct age-hardening procedure. SF928CH has a medium level of deoxidizers; this makes it suitable for casting in open systems, although the alloy can be used with success also in closed systems. SF928CH offers excellent fluidity in casting; the as-cast tree is clean from oxide scales; it has extremely high shininess and lustrous color after finishing. MSDS.
