Ultra-high temperature materials

What are ultra-high temperature materials   Ultra-high-temperature materials refer to the most heat-resistant high-grade materials that can be used as usual under severe environments such as stress and oxidation, and at an ultra-high temperature of about 2000°C. Research and application of ultra-high temperature materials    1. Refractory metal Refractory metals (W, Mo, Ta, Nb, Zr, etc.) […]

Titanium but not just titanium

Titanium and its alloys have many advantages as surgical implant materials, such as low density, high strength, good toughness, good biocompatibility, non-toxicity, low elastic modulus, good corrosion resistance, and low X-ray absorption rate Etc., thus occupying an increasingly important position in medical metal materials. Titanium and its alloys can be used for the repair and […]

Overview of rare earth metals and intermediate alloys

The vast majority of single rare earth metals and their intermediate alloys are used to produce new rare earth metal materials such as neodymium iron boron, samarium cobalt permanent magnet and super magnetostriction and non-ferrous metal alloys such as AI-RE, Mg-RE, Cu-RE, Zn- RE, W-RE, Mo-RE, etc. In addition, there are a few rare earth […]

Process of high-density tungsten alloy

High-density tungsten alloy, also known as tungsten-based heavy alloy, is a type of alloy made of tungsten as the matrix element (85% ~ 99% mass fraction) with the addition of Ni, Cu, Fe and other alloy elements by liquid phase sintering. The density is up to 16.5 ~ 19.0g / cc. The most commonly used are […]

History of Neodymium magnet

A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed independently in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available History General Motors (GM) and Sumitomo Special Metals independently discovered the Nd2Fe14B compound almost simultaneously in 1984. The research was […]
