stainless steel powder

Submitted by admin on Mon, 06/24/2019 - 01:24

Metallic stainless steel powder made of stainless steel alloy. The particles were regular spheres with a density of 7.9g/cm3 and average particle size <33 m. With good corrosion resistance and durability, the ball particles can be positioned on the surface of the film in parallel and distributed throughout the film, forming a shielding layer with excellent hiding power to block the moisture. Can also be used for sandblasting machine to process some of the higher accuracy of the workpiece.

Platinum carbon catalyst belongs to noble metal catalyst with black powder appearance and molecular weight of 195.08. Platinum carbon catalyst is a kind of carrier catalyst which supports platinum onto activated carbon. Can be used in pharmaceutical, electronic and other fields, the application is more extensive.

what is titanium

Submitted by admin on Thu, 06/20/2019 - 01:11

Titanium is best known for its corrosion resistance, which is almost as good as platinum. Titanium is not corroded by dilute sulfuric acid, dilute hydrochloric acid, chlorine gas, chlorine solution and most organic acids, but it can still be dissolved by concentrated acid.

Inconel 718 is a precipitation hardening nickel-chromium-iron alloy containing niobium and molybdenum. It has high strength, good toughness and corrosion resistance in high and low temperature environment at 700 ~C. The state of supply may be solid solution treatment or precipitation hardening. Inconel 718 Alloy,Inconel 718,nickel-chromium-iron alloy

what is Osmium powder

Submitted by admin on Wed, 06/19/2019 - 01:48

Osmium, 6 cycles Ⅷ group element periodic table, a member of platinum group metals. Element symbol Os, atomic number 76, relative atomic mass 190.2, belongs to heavy platinum group metal, which is the densest metal known at present.

Uses of iridium

Submitted by admin on Tue, 06/18/2019 - 01:36

Iridium: belongs to the periodic table Ⅷ transition element, atomic number 77, atomic number 192. 2, face-centered cubic lattice, is a rare precious metal material. Two new elements, osmium and iridium, were found in the black powder left at the bottom of the vessel when the crude platinum was dissolved in royal water. Iridium content in the earth's crust is one part in ten million and is often dispersed in alluvial and sandy deposits with platinum series elements.

Introduction to Titanium Carbide (TiC) Applications

Submitted by admin on Tue, 06/18/2019 - 01:27

Titanium carbide chemical formula TiC. Steel gray crystal with metallic luster. It has thermal conductivity and electrical conductivity, and its electrical conductivity decreases with increasing temperature, so it exhibits metallic properties. It is a very hard, high melting point compound with hardness second only to diamond and a microhardness of 2850 kg/mm. It belongs to NaCl type tetragonal system, lattice constant a=4.173×10cm, melting point 3150°C, boiling point 4820°C, relative density 4.9.
