2024-01-05 18:00:06

   Molybdenum bar appearance

   The surface is silver-gray metallic luster. The surface of straightened molybdenum strip has dark gray oxide layer. There is no water absorption and oil immersion on the surface of the product.

  Molybdenum strip grade

  According to chemical composition and usage, it can be divided into two grades, GMPM-1 and GMDM-4.

   Molybdenum bar - application

  (1) GMPM-1 is mainly used for electrical discharge wire cutting and raw materials of molybdenum wire for electric light source materials.

   (2) GMDM-4 is mainly used for alloy additives and molybdenum based alloys.

   Packaging

  GMPM-1 products are packed in wooden or cartons with grooved foam plastic boards, GMDM-4 is packed in 100 kg or 250 kg rust-proof iron drums, and the special requirements are determined through consultation between the two parties.

   Molybdenum alloy strips for storage and transportation should be moisture-proof and anti-collision. Store in a ventilated, dry and acid free atmosphere, strictly prevent oxidation, storage period should not exceed six months.
