What limitations restrict the wide popularization of Monel Alloy in general manufacturing?

First, its high nickel and copper content pushes raw material costs far higher than ordinary stainless steel, raising overall component investment. Second, Monel Alloy cannot resist oxidizing acids like nitric acid, limiting its use in mixed acid chemical production lines. Third, aged Monel K-500 brings higher machining costs due to severe work hardening. These defects make Monel Alloy only chosen for special fluoride and marine anti-corrosion equipment, rather than ordinary structural parts without strict fluoride corrosion resistance requirements.
