Description

Alloy Nmg0,05v is used: for the production of forged bars for the manufacture of thin-walled tubes and strip thickness of 0.05−2.0 mm, used in electronics and other industries; the cathodes.

Note

Alloy vacuum smelting.
The alloy Nmg0,05v according to ST SEV 1257−78 match the alloy NiMg0,05. The alloy Nmg0,05v increased Nickel content, increased content of silicon, the standard oxygen content.
