The primary member of the refractory metals are Nb, Ta, Mo, W, and Re. As one of the most dominate industrial refractory alloy, Nb C103 (89Nb10Hf1Ti), this precipitation strengthened niobium alloy is used in aerospace appliions in sustained high temperature operating environments, particularly in the propulsion systems where regenerative cooling is not available.

· These alloys use 9 refractory metals (Cr, Hf, Mo, Nb, Re, Ta, V, W, and Zr) and can also contain other elements, such as Al, Ti, Si, Co, Ni, C, and N. These additional elements can decrease alloy density (RCCA densities range from to g/cm 3 ), may form compounds that may strengthen the alloy, and may influence other properties such as hardness and environmental resistance.
Metals With High Melting Points
Refractory Metals. There are two accepted definitions for refractory metals. One states a metal must have a melting point above 2200 °C, whilst the other states all metals with a melting point above 1850 °C are considered refractory metals. Using the broader definition, the following 14 metals are classified as refractory metals.
Refractory metals – GOON
· Refractory metals are a class of metals that are extraordinarily resistant to heat and expression is mostly used in the context of materials science, metallurgy and definition of which elements belong to this group differs. The most common definition includes five elements: two of the fifth period (niobium and molybdenum) and three of the sixth period (tantalum ...
Refractory Metals, What exactly are they
· Refractory metals are a group of special elements or alloys that happen to have very high melting points and are also resistant to the damages of corrosion, wear and deformation. They have several uses, suitable for different industries, including heat exchangers, charge carriers, capacitors, jet engines and much more.

Acidic RefractoryAcidic Refractory Materials Company RS
Acidic Refractory Uses. Because the properties of acidic refractory are quite different from basic refractory, the acidic refractory uses are also different from that of basic anti slag corrosion performance, refractoriness under load, the volume change at high temperature burning and thermal shock resistant ability determines the using temperature of acidic refractory.
