ZlSrM 750-125 (ZlSrM 75-12,5)
The alloy is suitable for all types of cold working; For machining, it is preferable to use a welded or hardened state; during investment casting, the alloy should be melted in vacuum and poured under a protective atmosphere. Sample 750, the color is bright yellow. Melting point 885−900 ° C.
For making jewelry, souvenirs; alloy soldered well and is used for the manufacture of coated enamel
