Product Overview
Ferromolybdenum (FeMo) is the primary alloying additive for molybdenum in steelmaking and foundry applications. JF Metals supplies 9 standard grades covering Mo 55–75%, meeting GB/T, ASTM, and customer-specific requirements.
Pricing basis: Mo 60%. Shipments with higher Mo content are priced at a premium; lower Mo at a discount — calculated against the base Mo 60% quotation. Each lot is sampled, sealed, and tested, with full Mill Test Certificate (MTC) provided.
Available in lump (10–100mm) and crushed granular sizes, packed in 100kg steel drums or 1MT jumbo bags, with neutral / buyer-branded packaging on request.
