Molybdenum Strips
Molybdenum Strip Appearance
The surface is silver-gray metallic luster, the surface of the straightened molybdenum strip has a dark gray oxide layer, and the surface of the product has no water absorption and oil immersion.
Grades
According to the chemical composition and use of different are divided into GMPM-1, GMDM-4 two grades

Molybdenum Strip Uses
(1) GMPM-1 is mainly used as a raw material for wire EDM and electric light source material molybdenum wire.
(2) GMDM-4 is mainly used as a raw material for alloy additives and molybdenum-based alloys.
Packaging GMPM-1 product is packed in wooden boxes or cartons, with slotted foam sheets, GMDM-4 is packed in 100kg or 250kg anti-rust iron drums, and the special requirements are determined by consultation between the two sides.
When storing and transporting molybdenum alloy strips, they should be moisture-proof and collision-proof. Store in a ventilated, dry and acid-free atmosphere, strictly prevent oxidation, and the storage period should not exceed six months.
