There are many benefits of non-ferrous metals for electrical wiring and electronics. These metals are magnetic-free, making them suitable for a variety of applications. Because of this, they are often more expensive and in greater demand than ferrous metals. Furthermore, their chemical properties do not change during the recycling process. On the other hand, ferrous […]

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 […]

The alloying principle of molybdenum is similar to that of tungsten. All the strengthening methods used to improve the heat resistance of tungsten are basically applicable to molybdenum. There are mainly the following types: solid solution strengthening, precipitation strengthening, dispersion strengthening and composite strengthening. Solution strengthening Solid solution strengthening includes the addition of trace elements […]

The most common definition of refractory metals includes five elements: niobium, molybdenum, tantalum, tungsten, and rhenium. They share some properties, including a melting point above 2000 °C and high hardness at room temperature. Their machineabilities are quite different, we will introduce the processed & applications for these metal in solid bar form here. Most common processing […]

Refractory materials are those substances with high temperature and pressure resistance. Some of the most common types are bricks, which are rectangular in shape. They are available in standard and special dimensions. They are also used for nuclear power plants and other applications requiring high temperatures. The properties of refractory materials vary according to the […]

In refractory metals, the ductile-brittle transition temperature of tantalum is lower than -196℃, which has the best low-temperature plasticity. While maintaining this characteristic, it should be alloyed to increase its high-temperature strength. Tantalum alloys can be strengthened by solid solution strengthening, precipitation strengthening and a combination of both. The best solid solution strengthening elements are […]

Although many nitinol applications are not well-known to the public, some applications are quite routine and familiar. The spectacle frame made of Nitinol severely deformed and then returned to normal. Similarly, a few years ago, when mobile phone antennas were made of Nitinol, they could bend without breaking or permanently bending. Another superelastic application of […]

The production efficiency of boron nitride produced by chemical vapor deposition is high, but this method is easy to introduce pores and impurities into the sintered body and anisotropy caused by hot pressing. This makes its application very limited, especially in high temperature and oxidizing environments. Pyrolytic boron nitride materials have excellent physical and chemical […]

YTTRIUM, ZIRCONIUM, NIOBIUM, MOLYBDENUM, RUTHENIUM, RHODIUM YTTRIUM Atomic symbol: Y Atomic weight: 88.90585 Atomic number: 39 Electron configuration: 2-8-18-9-2 Oxidation states: +3 State of matter: solid Heavy metal, brittle Discovered in 1794 by Johan Gadolin Boils at 3337°C, melts at 1529°C Notes: Yttrium is an iron gray, lustrous, and darkens when exposed to light. It is […]

Rare-earth intermetallic compounds are metal compound phases formed between rare-earth metals and other metals or similar metals. They mainly use the special physical and chemical properties of rare-earth intermetallic compounds to prepare new rare earths for various purposes using various processing and manufacturing techniques. Functional Materials. At present, there are the following rare earth metal […]
