Pure-molybdenum-bar

Product Introduction

Shaanxi Chuanghui Daye Metal Material Co., Ltd. proudly offers the Pure-Molybdenum-Bar, a high-performance product known for its excellent thermal conductivity, outstanding corrosion resistance, and remarkable high-temperature strength. Manufactured from ultra-high purity molybdenum, each Pure Molybdenum Rod undergoes advanced electron beam melting, forging, and precision machining to ensure uniform density and fine grain structure. Our Pure Molybdenum Rod is suitable for industries requiring extreme durability and stability under harsh conditions. We provide both standard and custom sizes to meet diverse industrial needs.

Pure molybdenum bar is a high-purity molybdenum product, mainly composed of molybdenum (Mo), with a purity usually exceeding 99.95%. Pure molybdenum rods have high melting points, good thermal conductivity, and low thermal expansion properties, exhibiting excellent oxidation resistance and strength at high temperatures.

Sizes and Standard

Our pure molybdenum bar size range in diameter from 3-150mm*L, customized

Molybdenum bar order ships with standard ASTM B387.

Features

High melting point: The melting point of pure molybdenum is 2623 ℃, which makes it perform well in high temperature environments.

Good thermal conductivity: Pure molybdenum rods have excellent thermal conductivity and are suitable for applications that require good heat dissipation.

Low thermal expansion performance: When the temperature changes, the size of pure molybdenum rods changes relatively little, making them suitable for use in precision instruments and equipment.

Antioxidant: At high temperatures, pure molybdenum rods can resist oxidation and extend their service life.

Quality Requirements:

Surface of forged Moly bar can be allowed to have oxidation film and slight traces of forging;

Surface of grinding Moly bar shows metallic luster, no significant oxidation phenomenon;

Both the surface of Moly bar without layering, crack, burr, longitudinal crack and other defects;

Application

The Pure-Molybdenum-Bar is widely used in industries that demand high performance and reliability:

• Metallurgy: Furnace components, heating elements, and high-temperature structural parts.
