Copper Tungsten Rods combine copper's high conductivity with tungsten's durability. This unique material rod is ideal for demanding applications because of its exceptional thermal and electrical conductivity. Astech Tubes is a leading manufacturer & supplier of Tungsten Copper Rods to industries worldwide. These rods contain 50% of the copper and 50% of tungsten and are used in many critical applications for efficiency in high performance environments.
The Tungsten Round Bar range is crafted with precision, available in diameters from 0.75mm to 127mm and lengths ranging between 3.81mm to 1000mm, conforming to the ASTM B702 standard. The ASTM B777 Flat Bar is used extensively in the automotive, aerospace and nuclear industries because of its excellent thermal and electrical conductivity. These properties make rods vital for applications involving extreme conditions, high temperatures and electrical discharges.
Our tungsten copper rod's custom designs meet diverse industrial needs. The copper tungsten R07004 hollow bar is engineered to reduce weight without compromising strength, making it perfect for extended applications. Tungsten Square Bars and Alloy Hex Bars also enhance strength and geometric adaptability for critical structural uses. In addition, we provide Tungsten Carbide Round Bars and ASTM B777 Tungsten Bright Bars and various other rods that are safe to use.
We prioritise quality and adhere to stringent industry standards for all tungsten copper rods. Each batch undergoes rigorous testing to ensure compliance with ASTM standards, such as ASTM B702 and ASTM B777, guaranteeing consistent performance and reliability. Our high-quality control tests involve thermal conductivity tests, electrical conductivity checks and dimensional accuracy assessments. As one of the trusted tungsten copper bar manufacturers, we are committed to meet the demands of diverse industries with highest quality products.
