ZlSr750-250 (SLCP 75-25)

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. Test 750, color green. Melting point 1040 — 1045 ° C

For making jewelry, souvenirs; alloy soldered well and is used for the manufacture of coated enamel
