Chemical Etching with Molybdenum

Molybdenum is ideal for parts used in the defense, aerospace, and energy industries because of its high temperature tolerance, corrosion resistance, thermal conductivity, and high melting point (2,623° C).

Molybdenum—often called Moly or Mo—comes in various alloys or mixtures, such as molybdenum-lanthanum and molybdenum-copper. It’s a silver-gray refractory metal, present in many oxidation states (such as molybdenum(VI) oxide (MoO3) and Molybdenum dioxide (MOO2),

We welcome your questions about how to use molybdenum for your parts.

Types of Molybdenum used at E-Fab

Molybdenum and its alloys are known for their high melting point and strength at elevated temperatures. Alloys with steel, nickel, or tungsten increase specific metal properties, including hardness, corrosion resistance, or creep resistance.
