Molybdenum Seamless Tube

Product Introduction

The Molybdenum Seamless Tube supplied by Shaanxi Chuanghui Daye Metal Material Co., Ltd. is a high-performance product designed for extreme environments that demand exceptional thermal stability and corrosion resistance. Made from high-purity molybdenum, this seamless tubing demonstrates superior mechanical strength, dimensional precision, and chemical inertness. It is ideal for use in high-temperature furnaces, electronic components, vacuum systems, and aerospace applications.

With over 30 years of expertise in the rare metal industry, Chuanghui Daye manufactures every Molybdenum Seamless Tube using advanced melting, rolling, and machining techniques under strict ISO 9001:2015 quality control standards. The material’s purity and microstructure ensure consistent performance, minimal contamination, and long service life even in highly corrosive or high-vacuum environments.

The product is available in a variety of diameters, wall thicknesses, and lengths, with both standard and custom specifications according to ASTM, GB, and ISO standards. This makes it a preferred choice for industrial users seeking reliable and precision-engineered molybdenum tubing solutions.

Molybdenum seamless tube shall be made by any seamless method that will yield a product meeting the requirements of this specification.

Specification: Outer diameter Φ(1.0~50)mm× wall thickness (0.5~5)mm×Length (50~1000)mm

Main characteristics

1. Easy to process.

2. High intensity. Molybdenum and molybdenum alloys have high strength.

3. Good electrical and thermal conductivity. Molybdenum is second only to silver, copper and gold in conducting electricity and heat.

4. Good corrosion resistance. The surface of molybdenum is easy to naturally produce a layer of dense and firm protective film, which can well protect the matrix from corrosion.

Packaging & Shipping

Packing: Inner packing is moisture proof paper and thicker foam

Outer packing is exporting wooden box

Our Shipment Methods:

By express EMS,TNT,DHL,UPS,FedEx
